▼ This enquiry addresses a gap in the literature in relation to the conceptual development of Recognition of Prior Learning. Generally, research in RPL comprises large inventories and audits of practice as this enquiry shows. Few qualitative studies are available and there is a dearth of theoretical development in the field. This thesis explores perspectives of claimants and university managers/practitioners to explicate the issues at stake and explore the value of RPL in education. Using the practical philosophy of Gilles Deleuze and Felix Guattari (DG), the conceptualization of RPL is explored in policy and practice and their concepts are employed to reimagine RPL for learning, and as pedagogy, in adult university education. A hybrid method of grounded and rhizomatic theory informs the research approach. This involves searching the complex and diffuse territory of RPL to seek affirmative options for RPL theory and practice. Three case studies illustrate how different approaches to RPL offer different outcomes and were built on vague conceptualizations. In one setting, fifteen years of RPL claimant records is collated and analysed. Findings show that up to 70% of adult students in the case study had prior learning and gained exemptions. The data further indicates that RPL did not increase a student’s chances of completing a degree. This contradicts findings from international research. The research also challenges fears expressed by university managers that RPL poses a risk to academic standards, as claimants may not have foundational knowledge to succeed in university. The data indicates, however, that on the contrary, claimants have extensive prior learning; much of it accredited at levels 6 and 7 and are thus college ready. A model of learner directed RPL, used in another setting, is explored and theorized. This creative approach seamlessly integrates prior learning with new learning and thereby advances knowledge for the learner. The impact of the approach on the learner and learning is significant and offers new possibilities for RPL in education. It moves it on from the narrow purpose of reducing time in education and enhancing skills for employment. Accounts from participants in this enquiry show that they go to college to learn and they prize RPL most when it extends their knowledge – a dimension of RPL neglected in the literature. The thesis concludes with some affirmative options for re-cognising RPL in adult education.

▼ Owing to past injustices, the South African higher education sector is characterised by inequalities of resource allocation and of learning opportunities. Through the National Qualification Framework (NQF), recognition of prior learning (RPL) was established to address the previous inequalities in higher education and training. RPL can be used as a mechanism to offer non-traditional learners such as workers, adult learners, and community workers access to learning programmes in Library and Information Science (LIS) schools. It can also be used for up-skilling within LIS sector, to enable staff to migrate from paraprofessional to professional roles. LIS schools could possibly use this approach to offer experienced but unqualified library workers opportunities for progressive professional development and career growth. Despite it being a national policy and its obvious benefits, very little is known about RPL implementation in LIS schools in South Africa. This study was conducted to investigate the nature of RPL implementation in LIS schools in South Africa and make recommendations for effective and efficient RPL practice in these schools. The study used the questionnaire as the main data collection tool. In addition, document analysis was used to validate the collected data. The results of the study indicated that there were islands of good RPL practice in LIS schools in South Africa specifically with regard to the aspect of RPL assessment process. However, certain weaknesses were identified in other aspects of RPL implementation in LIS schools including the policy environment, training of personnel conducting RPL assessment and the quality management systems. Among other things, the study recommends that RPL quality management system (QMS) should ideally be driven by the head/chair of the school/department. Furthermore, an integrated student management system should be used to monitor the progression of RPL candidates through the formal academic system post RPL.

La mobilité devienne un partie intégrante de l’Internet des Object d’aujourd’hui, comme beaucoup d’applications (monitorage des animaux sauvage, suivi des cible dans le champs de bataille) sont impossible de mettre en œuvre juste avec des nœuds statiques. L’objective de cette thèse est de définir une nouvelle architecture de communication articule autour de la mobilité dans les réseaux avec pertes et à bas puissance (Low Power and Lossy Networks - LLNs) (réseaux des capteurs sans fils). Tout d’abord, nous avons analysé théoriquement l’auto configuration des adresses IPv6, fait avec toutes les optimisations disponibles dans Neighbor Discovery Optimization for IPv6 over 6LoWPAN. Cette étape est cruciale pour des protocoles qui donnent de support pour la mobilité dans des réseaux IP, comme MIPv6. Les résultats obtenues – taille des paquets trop grande et consumations énergétique importante pour les routeurs qui tournent Neighbor Discovery – n’ont amener a utiliser le IPv6 Routing Protocol for Low Power and Lossy Networks (RPL). RPL est développe d’el debout pour les LLN. Notre deuxième contribution sont améliorer les opérations du RPL pour mieux supporter les nœuds mobiles. Enfin, nous avons développe une mécanisme inter-couche – Mobility Triggered-RPL – qui profite des actions dans le protocole avec préambule X-Machiavel à la couche accès au medium dans le protocole RPL à la couche routage.

Mobility is becoming an integrating part of todays Internet of Things, as many applications such as wildlife monitoring or target tracking in the battlefield cannot be done only with the help of static nodes. The goal of this thesis is to provide new communication architecture articulated around providing mobility support in Low Power and Lossy Networks (LLNs). First we analyzed from a theoretical point of view the IPv6 address auto-configuration with all optimizations made in Neighbor Discovery Optimization for IPv6 over 6LoWPAN. This step is of crucial importance for protocols that offer mobility support in IP networks, such as MIPv6. Our findings, increased message size that leads to fragmentation and high energy consumption for routers that are involved in Neighbor Discovery message exchange, have lead us to use the IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) in order to provide mobility support. RPL is build from ground up with respect to LLN requirements. Our second contribution enhanced RPL operations to support mobility management. Finally, we proposed a cross-layer protocol – Mobility Triggered-RPL – that leverages actions from the X-Machiavel preamble sampling MAC protocol into RPL.

L'intérêt grandissant pour l'Internet des Objets (IdO) s'est traduit par le déploiement à grande échelle de réseaux dits LLN. Ceux-ci sont fortement contraints en matière de ressources et communiquent via des liens instables. Les protocoles de routages existants pour les réseaux traditionnels ne sont pas adaptés à ces caractéristiques. L'IETF a proposé un nouveau protocole de routage appelé RPL fondé sur IPv6 et spécifiquement conçu pour ces environnements. Cependant, il est exposé à de nombreuses attaques et la mise en place de mécanismes de sécurité représente un coût considérable. Les réseaux LLN introduisent donc de nouveaux enjeux quant à leur supervision et leur sécurité. Dans le cadre de cette thèse, nous étudions une approche de supervision pour la sécurité de l'IdO tout en limitant son coût. Nous évaluons tout d'abord les menaces auxquelles sont soumis les réseaux RPL en les classifiant au travers d'une taxonomie. Nous quantifions également les conséquences de deux attaques appelées l'attaque d'incohérence DAG et l'attaque du numéro de version. Nous nous concentrons ensuite sur les solutions pour la sécurité dans les réseaux RPL. Nous proposons une stratégie locale qui limite les attaques d'incohérences DAG et nous présentons une architecture de supervision distribuée orientée sécurité pour détecter des attaques complexes comme les attaques sur le numéro de version et compléter notre approche locale. Celle-ci nous permet de préserver l'énergie des nœuds en effectuant les activités de surveillance et de détection sur des nœuds dédiés. Nous quantifions ensuite les performances de cette architecture ainsi que la stratégie de détection proposée.

The growing interest for the Internet of Things (IoT) has resulted in the large scale deployment of Low power and Lossy Networks (LLN). These networks are strongly constrained in terms of resources and communicate using unstable links. In this context, existing routing protocols for traditional networks do not cope with all these constraints. The IETF has proposed a new routing protocol called RPL based on IPv6 and specifically designed for these environments. The RPL protocol is however exposed to a large variety of attacks. The deployment of security mechanisms may also be quite expensive for the nodes. Therefore, LLN networks present new challenges in terms of monitoring and security. In this thesis we propose to investigate a security-oriented monitoring approach for addressing the trade-off between security and cost in the IoT. In a first stage, we assess security threats faced by these networks by identifying and classifying attacks through a dedicated taxonomy. We also quantify the consequences of two major attacks called DAG inconsistency attacks and version number attacks causing over-consumption of node resources. We then focus our work on security solutions for RPL-based IoT. We propose a local strategy for addressing DAG inconsistency attacks. In order to detect complex attacks such as version number attacks and to complement our node-level approach, we…

Le réseau électrique a subi d’importantes évolutions ces dernières décennies, pour devenir ce qu’on appelle le Smart Grid. Le réseau électrique évolue actuellement d’une architecture centralisée vers une architecture décentralisée, tenant compte des consommations et sources d’énergies à caractère imprédictible et irrégulier. L’Advanced Metering Infrastructure est une architecture clé du Smart Grid qui permet des communications bidirectionnelles entre le consommateur et le fournisseur d’énergie. Les réseaux de compteurs intelligents qui constituent notamment cette architecture reposent communément sur des communications à courant porteur, une technologie qui est hautement sensible aux interférences. Malgré l’utilisation de protocoles de niveau 2 spécifiques, les technologies employées ne permettent pas de respecter les exigences de toutes les applications Smart grid. La plupart des technologies considérées pour les réseaux de compteurs intelligents sont de courte portée, chaque compteur ne peut communiquer directement avec le concentrateur. Les noeuds doivent collaborer entre eux, utilisant un protocole de routage tel que RPL pour atteindre la destination. Le but de cette thèse est d’adapter RPL à un environnement multi interfaces, et étudier comment l’hétérogénéité des interfaces peut améliorer la fiabilité et les performances d’un réseau de compteurs intelligents.

Since decades, the power grid is Under going a tremendous evolution, toward what is called the Smart Grid. The grid is actually evolving from a centralized architecture to a decentralized one, taking into account all the unpredictable sources and consumption. The Advanced Metering Infrastructure is the network dedicated to the Smart Grid that allows two-ways communications between the consumers and the energy providers. Smart Meters networks, that are part of this architecture, rely on powerline communications, a technology that is highly sensitive to interference. Despite dedicated layer 2 protocols, the employed technologies cannot fulfill most of smart grid applications requirements. The majority of smart meter network technology candidates are short range, each meter cannot reach the concentrator in one hop. Nodes need to collaborate, using a routing protocol like RPL to reach the destination. The goal of this thesis is to modify RPL to a multi interfaces environment, and study how interface heterogeneity could increase the reliability and the performance of a smart meter network.

Les Low Power and Lossy Network (LLN) sont des technologies Internet of Things (IoT) sans fil qui fonctionnent avec une puissance de traitement, une mémoire ou une puissance limitées. En outre, ils ont des liens caractérisés par des taux de perte élevés. Toutefois, en raison de leur faible coût et de leur facilité de manipulation, elles sont devenues populaires dans l'industrie 4.0. Par conséquent, pour que ces technologies puissent être intégrées dans l’industrie, elles doivent assurer une transmission fiable, rapide et stable. Le IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) est un protocole de routage vectoriel à distance spécialisé dans ces applications IoT. Son adaptabilité en a fait l’un des protocoles les plus populaires pour les LLNs. Cependant, sa transmission unidirectionnelle en amont n’est pas suffisante pour garantir la fiabilité de la transmission. Il en résulte un défi pour l’industrie et différentes fonctions et stratégies ont été proposées pour résoudre ce problème. Malheureusement, nombre de ces stratégies ne peuvent être reproduites pour différents environnements et nécessitent des compromis dans d’autres domaines. Dans cette thèse, notre objectif est de fournir une RPL personnalisée afin qu’elle puisse assurer la fiabilité de la transmission tout en maintenant un faible retard et une faible fluctuation. À cette fin, nous proposons différentes fonctions et algorithmes qui permettent l’extension des multitrajets en RPL.

The Low Power and Lossy Network (LLN) are wireless Internet of Things (IoT) technologies that operate with limited processing power, memory, or power. Furthermore, they have links characterized by high loss rates. However, due to their low cost and easy handling, they have become popular in the industry 4.0. Therefore, for these technologies to be incorporated into the industry, they need to ensure reliable, fast, and stable transmission. The IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) is a distance vector routing protocol specialized in these IoT applications. Its adaptability has made it one of the most popular protocols for LLNs. However,its one-way upstream transmission is not sufficient to guarantee transmission reliability. This has resulted in a challenge to the industry and different functions and strategies have been proposed to address this problem. Unfortunately, many of these strategies cannot be replicated for different environments and require trade-offs in other areas. In this thesis,our goal is to provide a customized RPL so that it can ensure transmission reliability while maintaining a low delay and fluctuation. For this purpose, we propose different functions and algorithms that allow the extension of multi-path in RPL.

Les Réseaux de Capteurs Sans Fil (RCSF ou Wireless Sensor Network - WSN) sont l'une des technologies les plus importantes du 21ème siècle. La plupart des chercheurs et les analystes estiment que, dans un proche avenir, ces micro-capteurs seront intégrés partout dans l’environnement de notre vie quotidienne. Ces dernières années, l'Internet des Objets (Internet of Things - IoT) est également une des technologies émergentes qui se développe rapidement. Deux nouveaux standards permettent de déployer des réseaux sans fil de faible consommation énergétique connectés à internet : le protocole 6LowPAN (Low power Wireless Personal Area Networks) qui permet notamment d’apporter l’adressage IPv6 aux capteurs grâce à l’encapsulation et la compression des données et le protocole de routage RPL (IPv6 routing protocol for low-power and lossy network) qui permet à l’information de circuler dans les WSN de proche en proche à un faible coût énergétique. Bien que le développement de ces techniques soit extrêmement rapide, plusieurs problèmes causés principalement par le manque de ressources des micro-capteurs (puissance limitée de traitement, problèmes de bande passante et de connexion des liens avec perte de données, problème de ressource énergétique limitée) demeurent et doivent être résolus, notamment pour les applications agro-environnementales.

The wireless sensor network (WSN) is one of the most important technologies of the 21st century. Most researchers and technical analysts believe that in the near future, these micro-sensors will be integrated into the environment of our daily lives. In recent years, the IoT (Internet of Things) and WoT (Web of Things) technologies also have great forwarding. Especially, the IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) protocol has allowed the use of IPv6 protocol stack in the field of WSN, thanks to its encapsulation and compression mechanisms in IPv6 packet header. Moreover, the RPL (IPv6 Routing Protocol for Low-power and Lossy Network) provides such a powerful routing function that can be applied for a variety of application scenarios. These two key standards of IoT and WoT technologies for WSN can be used in an IPv6 stack, and they will successfully achieve the connection between Internet and micro-sensors. Thus, due to the availability of IPv6 address (128-bit), all the communicating objects, such as smart device, sensor, and actuator, can be connected to the Internet. That is the greatest advantage brought by the IoT. Although the progress of these techniques is extremely fast, several issues caused by resource constraints of micro-sensor (limited processing power, bandwidth and lossy connection link, and energy), such as QoS, energy efficient, robustness and lifetime of WSN, and the most important, the special requirement of agricultural applications. Notice that Precision Agriculture is are still very challenging and waiting to be solved. Essentially, these open questions would dabble in the aspects like telemedicine, remote home automation, industrial control…

L’intérêt croissant de la communauté scientifique et industrielle ces dernières années pour les réseaux de capteurs sans fil (RCSF), a conduit à la définition de nouveaux protocoles normalisés prenant en compte les spécificités matérielles des nœuds utilisés. Dans la couche réseau, le protocole RPL (de l’acronyme anglais IPv6 Routing Protocol for Low-power and Lossy Network) a été proposé en 2012 par l’IETF, comme standard de routage pour les réseaux dont les nœuds sont de type "LLN" (Low-power and Lossy Network), i.e. caractérisés par une faible autonomie énergique et transmettant sur des liens radios dotés d’un taux de perte de données élevé. Dans cette thèse, nous nous intéressons à l’optimisation du routage dans ces réseaux (notamment ceux utilisant la pile protocolaire TCP/IP), ainsi qu’à leur interconnexion efficace à Internet à des coûts soutenables. Tout d’abord, nous proposons deux fonctions d’objectif organisant le routage avec RPL. La première se sert de l’unique critère énergétique, avec comme objectif principal la maximisation de la durée de vie du réseau. Pour ce faire, nous avons implémenté un modèle d’estimation d’énergie, intégré par la suite aux nœuds pour leur permettre d’estimer en temps réel leur énergie résiduelle. La deuxième fonction d’objectif proposée, vise à combiner plusieurs critères pour la prise en compte de la qualité de service durant le routage. Nous développons un modèle à base de la logique floue pour mettre en œuvre la combinaison. En effet, elle nous permet d’obtenir un bon compromis entre les différentes entrées et requiert une empreinte mémoire faible. Dans la dernière partie de cette thèse, nous concevons et implémentons une architecture d’activation de passerelles permettant d’assurer une connexion Internet efficace de divers RCSFs utilisant RPL, pour la réalisation de la vision de l’Internet des Objets

In recent years, the growing interest of scientific and industrial community has led to the standardization of new protocols that consider the unique requirements of Wireless Sensor Networks (WSN) nodes. At network layer, RPL (IPv6 Routing Protocol for Low-power and Lossy Network) has been proposed by IETF as the routing standard for network that uses LLN nodes, namely, those where both nodes and their interconnects are constrained. They operate on low-power embedded batteries and use lossy links, making communications unreliable and lead to a significant data loss rates. This thesis aims to optimize the routing in WSNs (especially those using TCP/IP protocol stack), as well as their efficient and cost-effective connection to the Internet. First, we have proposed two new RPL objective functions. The first uses as unique routing criterion, the node remaining energy with the goal of maximizing the network lifetime. An energy model that allows the nodes to dynamically estimate their remaining energy at runtime has been implemented and integrate to the protocol. The second objective function uses fuzzy logic reasoning to combine several criteria to take Quality of Service into…

De nouveaux protocoles ont été standardisés afin d'intégrer les réseaux de capteurs sans fil (WSN) dans l'Internet. Parmi eux, RPL pour la couche routage et IEEE 802.15.4 pour la couche MAC. L'objectif de cette thèse est d'améliorer ces protocoles en prenant compte des contraintes énergétiques des dispositifs du WSN. Tout d'abord, nous avons conçu une nouvelle méthode de diffusion dans la norme IEEE 802.15.4, afin d'assurer une livraison fiable des paquets de contrôle des couches supérieures. Ensuite, nous avons fourni une évaluation exhaustive de RPL, en soulignant un problème d'instabilité qui génère une surcharge d'énergie importante. Compte tenu que la durée de vie des WSN est très limitée, nous avons aussi proposé une nouvelle métrique de routage qui identifie les goulets d'étranglement énergétiques afin de maximiser la durée de vie du réseau. Enfin, en couplant cette mesure avec une version multiparent de RPL, nous avons résolu le problème d'instabilité souligné précédemment.

New protocols have been standardized in order to integrate Wireless Sensor Networks (WSN) in the Internet. Among them, the IEEE 802.15.4 MAC layer protocol, and RPL, the IPv6 Routing Protocol for Low-power and Lossy Networks. The goal of this thesis is to improve these protocols, considering the energy constraints of the devices that compose the WSN. First, we proposed a new MAC layer broadcast mechanism in IEEE 802.15.4, to ensure a reliable delivery of the control packets from the upper layers (especially from RPL). Then, we provided an exhaustive evaluation of RPL and highlighted an instability problem. This instability generates a large overhead, consuming a lot of energy. Since the lifetime of WSN is very limited, we proposed a new routing metric that identifies the energy bottlenecks and maximizes the lifetime of the network. Finally, by coupling this metric with a multipath version of RPL, we are able to solve the instability problem previously highlighted.

▼ Finding a sustainable and structural material for the civil infrastructure domain, while remaining financially feasible, is a challenge for engineers. Recycled Plastic Lumber (RPL) is identified as an excellent sustainable material used by the construction industry in non-load bearing applications. There is a demand and an opportunity to resolve the aforementioned challenge by migrating RPL into structural applications. Although RPL has significant sustainable and structural advantages, such as light weight, low cost and high resistance to environmental degradation, its usability in the civil infrastructure applications is still at its early stages due to a lack of design guidelines. Furthermore, due to the brittleness of the RPL material, joining RPL components impose another challenge for engineers. Recently, however, many structural industries have considered adhesive binding as an excellent candidate for replacing the traditional joining methods (e.g. bolting and riveting) for joining load-bearing components, especially for scenarios involving joining brittle materials such RPL. The attractiveness of adhesives stems from their unique combinations of properties, which include: high strength, light weight, dimensional stability, high resistance to environmental degradation and ease of use. Due to these unique characteristics and advantages, the use of adhesive joints is on the rise in structural applications. On the other hand, the traditional bolted joint methods have gone a long way in creating appropriate technologies and gained years of design experience, which cannot be easily replaced. Accordingly, switching from traditional joining methods to adhesive bonding in civil infrastructure applications requires a large investment to establish a level of understanding comparable to that associated with traditional joining methods. In particular, it is crucial to characterize and fully understand bonded joint behaviors, strength and failure properties, and to be able to predict them for given geometries and loads. This research addresses both challenges by providing design guidelines for utilizing RPL in load-bearing structural application and by fully characterizing the behavior of adhesively bonded RPL joints. For addressing the first challenge, this research covers structural and sustainability assessments of an RPL beam. Experimental and numerical results of the four-point bending structural assessment of RPL beams reinforced with Glass Fiber Reinforced Polymer (GFRP) indicate that as the amount of GFRP reinforcement area increases, the stiffness of the RPL increases up to four times linearly The results also indicate that optimizing the beam section by using an I-shape beam or a hollow beam can reduce the weight and increase the surface area, improving the heat treatment process while maintaining 90%-95% of the beam stiffness. Results of the three pillars of the sustainability assessment (environmental, economic and social) show that reinforced recycled plastic beams have great environmental benefits compared… Advisors/Committee Members: Issa, Mohsen (advisor), Foster, Craig (committee member), Chudnovsky, Alexander (committee member), Shabana, Ahmed (committee member), Reddy, Krishna (committee member).

Les Smart Grids visent à transformer le réseau électrique actuel en un réseau "plus intelligent" où la production énergétique est décentralisée et automatisée, facilitant l'intégration des sources d'énergie renouvelables. Cette évolution est rendue possible grâce à l'utilisation d'un réseau de communication pour les multiples échanges de données hétérogènes des Smart Grids. L'objectif de cette thèse est de proposer un paradigme de communication efficace en termes de qualité de service pour les Smart Grids basé sur les réseaux de capteurs.Dans un premier temps, on s’intéresse au protocole standard RPL. Nous proposons une évolution de celui-ci à travers une nouvelle fonction objectif. Celle-ci tire parti de l’hétérogénéité matérielle des nœuds et des liens pour introduire la qualité de service. Cela permet à RPL de satisfaire les multiples et différentes exigences en termes de fiabilité, de latence et de priorité dans l'acheminement des données. Nos résultats montrent que notre approche permet bien la différentiation du trafic tout en réduisant la latence du routage et en économisant l'énergie.Nous proposons également d'améliorer l'utilisation du réseau de capteurs en y introduisant l’auto-organisation et la réduction des données. Le but est alors de prédire la valeur des données mesurées plutôt que de les transmettre.Une autre approche explorée est d'agréger les différents messages transitant sur le réseau tout en considérant leurs différentes exigences de qualité de service. Ces deux approches permettent ainsi de réduire la consommation d'énergie tout en respectant les exigences des différentes applications des Smart Grids.

Smart Grids aim to transform the current electric grid into a "smarter" network where energy production is decentralized and automated, which facilitates the integration of renewable energy resources. This evolution is made possible thanks to the use of a communication network for the multiple heterogeneous data exchanges of the Smart Grids. Hence, the aim of this thesis is to propose an efficient communication paradigm in terms of quality of service for Smart Grids based on wireless sensor networks.First, we study data routing in Smart Grids with the RPL standard. Nevertheless, RPL is not suitable for Smart Grid applications in terms of quality of service. Therefore, we propose an objective function for RPL that takes different features of both nodes and links into consideration. Results show that our approach improves network performance compared to existing solutions in terms of packet delivery ratio, network lifetime, latency and traffic differentiation.Then, we also propose a more efficient data collection by introducing self-organization and data reduction for these wireless sensors. The goal is to predict the value of the measured data rather than transmitting them. Another explored approach is to aggregate the different messages sent across the network while considering their different requirements in terms of quality of service.These two approaches reduce the energy consumption while…

▼ The growth of wireless networks has resulted in part from requirements for connecting people and advances in radio technologies. Recently there has been an increasing trend towards enabling the Internet-of-Things (IoT). Thousands of tiny devices interacting with their environments are being inter-networked and made accessible through the Internet. For that purpose, several communications protocols have been defined making use of the IEEE 802.15.4 Physical and MAC layers. The 6LoWPAN Network Layer adaptation protocol is an example which bridges the gap between low power devices and the IP world. Since its release, the design of routing protocols became increasingly important and the IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) emerged as the IETF proposed standard protocol for IPv6-based multi-hop Wireless Sensor Networks (WSN). This thesis considers that the sensor nodes form a large IPv6 network making use of above technologies and protocols, and that the sensor nodes are enabled to run one or more applications. It is also assumed that the applications and the sensor nodes to which they are associated, are not always active, alternating between active and inactive states. The thesis aims to design a new energy efficient communications solution for WSN by exploring the hypothesis that the network is aware of the traffic generated by the applications running in the sensor nodes. Therefore, the thesis provides two major contributions: 1) a cross-layer mechanism using application layer and network layer information to constrainRPL-defined routing trees (RPL-BMARQ); 2) an Application-Driven WSN node synchronization mechanism for RPL-BMARQ. RPL-BMARQ is designed as an extension to the RPLrouting protocol using information shared by the application and routing layers to construct Directed Acyclic Graphs (DAGs), allowing the nodes to select parents with respect to the applications they run. By jointly considering the neighbors of each node, the applications each node runs, and the forwarding capabilities of a node, we provide a communications solution which enables the data of every application and sensor node to be transferred, while keeping the overall energy consumed low by reducing the time the nodes are active and reducing the total number of multicast packets exchanged. Therefore, RPL-BMARQ helps reducing the network energy consumption since it restricts radio communication activities while maintaining throughput fairness and packet reception ratio high. The mechanism was evaluated using four scenarios with different network topologies and compared against "standard RPL". The results obtained show that the mechanism enables lower energy consumption since the nodes are more often put a sleep, reducing the total number of packets exchanged, while maintaining fairness and query success rates high. The Application-Driven WSN node synchronization mechanism for RPL-BMARQ was designed to maintain the sensor nodes synchronized… Advisors/Committee Members: Ricardo, Manuel.

▼ The intelligent connectivity of smart sensor devices commonly referred to as the Internet of Things (IoT) — is swiftly progressing productivity and communication levels and providing many functionalities throughout many organizations globally. The benefits heralded by the IoT’s revolution is threatened, however, by the general lack of understanding of IoT’s specific security demands thus, limiting its swift adoption and potential growth. Two distinguishing features of IoT that makes it unique are the interconnection of billions of smart devices, and the resource-constrained nature of smart “things”. However, most IoT devices and applications operate with either no security; limited or insufficient security to protect the data they transmit during operation due to their limiting properties like CPU, memory capacity, battery life and mobility. This issue is further compounded for IoT system designers, as a global security framework has not been well defined, and most IoT system designers lack the knowledge or expertise to design or define secure IoT systems since this is a new and emerging technology. The routing of data in the IoT network is a specific security area of concern. With the massive scale of data exchange between these devices, and no adequate security to protect the communication of data, compromising data routes becomes easy for attackers. This thesis therefore, proposes a secure routing communication framework called SecTrust, which scales on IoT size and provides acceptable network performances while not depleting the resource availability of these smart “things”. The proposed SecTrust is a secure Trust-based framework for IoT that provides a platform for trust computation, trust evaluation and trust formation among nodes. This framework provides a secure communication among the connected nodes. The framework further provides a system for the identification and isolation of malicious nodes operating within the network. In this system, every node computes the trustworthiness of its direct neighbours based on the computed direct trust value and the recommended trust value. While neighbours with high trust values are chosen for secure routing, nodes with lower trust values are categorised either as malicious, compromised, or perhaps selfish nodes that seek to preserve their resources like battery power. SecTrust consists of five main processes: trust calculation process, trust monitoring process, detection and isolation of malicious nodes, trust rating process and trust backup/recuperation process. The development of this system provides insight into the use of modelling and analytical tools in building effective designs for P2P networks, through the design and development of trust computation, trust creation and trust propagation mechanisms, which are embedded, tested and validated using an IoT platform. The utility of SecTrust as a promising framework for IoT systems is demonstrated via its practical applications comprising: detection and isolation of malicious actors, management and sustenance of… Advisors/Committee Members: Gutierrez, Jairo A (advisor), Sarkar, Nurul I (advisor), Ray, Sayan Kumar (advisor).

▼ Recognition of prior learning, better known as RPL, was introduced to training institutions in South Africa after the fall of Apartheid. The objective of RPL was to redress inequalities brought about by Apartheid when disadvantaged groups had less access to training opportunities. RPL was introduced with a combination of associated training and education initiatives such as the National Qualification Framework and the South African Qualifications Authority, all directed for a similar purpose. The South African Nursing Council agreed with the principles of RPL and published a policy document aimed to guide nurse educators to enhance RPL implementation in South African nursing education institutions. Despite the support from accessible legislative and regulatory documentation, RPL is implemented insufficiently in nursing education institutions. The lack of RPL implementation was also identified by the researcher in the Limpopo College of Nursing. This College of Nursing can be described as a symbol of post-Apartheid re-integration whereby nursing colleges centralised into one administrative management office with campuses, satellite campuses and over 120 nurse educators. The research question asked was what are nurse educators’ perceptions of the implementation of RPL in nursing colleges in Limpopo Province? The aim was to support nurse educators to enhance the implementation of RPL in nursing colleges in Limpopo Province. A qualitative, phenomenological, explorative, descriptive and contextual research design was followed. Seven (n=7) individual, in-depth, unstructured interviews were conducted with nurse educators employed at the X Campus and Y Satellite Campus of the Limpopo College of Nursing. Transcribed interviews were analysed and resulted in three main themes and nine sub-themes. Firstly, the participants voiced their agreement that RPL should be implemented and identified specific benefits and challenges thereof. Secondly, there should be a RPL assessment package that should be open and transparent, be able to assess academic performance against college standards and should minimise inequalities. The third main theme was the need for enhanced awareness of RPL implementation in nursing colleges. Nurse educators lack knowledge about RPL and should therefore be more awareness thereof. In addition RPL should be promoted as a beneficial mechanism to the learning process. These results were discussed with a literature integration and in the majority of results literature confirmed these findings. Conclusion statements were formulated from the research results and served as the basis for the formulation of recommendations to support nurse educators with the implementation of RPL in nursing colleges in Limpopo Province. The recommendations were directed to firstly the policy makers in nursing education; secondly to the nursing education institutions and thirdly to the nurse educators. Areas for further research were listed. Strategies to enhance trustworthiness and the adherence of ethical considerations were…

A Wireless Sensor Network is formed of several small devices encompassing the capability of sensing a physical characteristic and sending it hop by hop to a central node via low power and short range transceivers. The Sensor network lifetime strongly depends on the routing protocol in use. Routing protocol is responsible for forwarding the traffic and making routing decisions. If the routing decisions made are not intelligent, more re-transmissions will occur across the network which consumes limited resources of the wireless sensor network like energy, bandwidth and processing. Therefore a careful and extensive performance analysis is needed for the routing protocols in use by any wireless sensor network. In this study we investigate Objective Functions and the most influential parameters on Routing Protocol for Low power and Lossy Network (RPL) performance in Contiki (WSN OS) and then evaluate RPL performance in terms of Energy, Latency, Packet Delivery Ratio, Control overhead, and Convergence Time for the network. We have carried out extensive simulations yielding a detailed analysis of different RPL parameters with respect to the five performance metrics. The study provides an insight into the different RPL settings suitable for different application areas. Experimental results show ETX is a better objective, and that ContikiRPL provides very efficient network Convergence (14s), Control traffic overhead (1300 packets), Energy consumption (1.5% radio on time), Latency (0.5s), and Packet Delivery Ratio (98%) in our sample RPL simulation of one hour with 80 nodes, after careful configuration of DIO interval minimum/doublings, Radio duty cycling, and Frequency of application messages.

En Wireless Sensor Network består av flera små enheter som omfattar de förmåga avkänning en fysisk egenskap och skicka den hoppa med hopp till en centrala noden via låg effekt och kort sändtagare räckvidd. Det sensornätverk livslängd är starkt beroende av routingprotokoll som används. Routingprotokoll är ansvarar för att vidarebefordra trafik och göra routing beslut. Om dirigeringen beslut som fattas inte är intelligenta, kommer fler återsändningar förekomma på nätverk som förbrukar begränsade resurser trådlösa sensornätverk som energi, bandbredd och bearbetning. Därför är en noggrann och omfattande prestanda analys behövs för routingprotokoll används av alla trådlösa sensornätverk.

▼ Wireless Sensor Network (WSN) devices are small, low-powered sensors that are deploy- able for long-periods of time to provide information on the local evironment to the world at large. These devices are designed to be deployed and operated for extended periods of time with a minimum amount of maintenance. These inexpensive devices open up a new eld in computing, providing the ability for small groups to gather data on their environment for use in myriad tasks. This work presents the Hierarchical network of Observable devices with Itinerant Sinks Transporting data (HOIST), a WSN architecture I designed to alleviate the e ects of the disadvantages that lie within a WSN deployment. I began this design by dividing the traditional sender-sink model into a three-tier hierarchial model. This model separates the senders and the ultimate destination sink into tiers joined together by a series of bridging sinks. These bridging devices each control a smaller fragment of the collectors, enabling downward routing to a larger degree than otherwise possible with a traditional single DAG, while also coordinating the transmission of data between the collectors and the destination sink. Furthermore, HOIST adds in mobility to the model, allowing the highest tier sink to move about the deployment area, minimizing any set of bridging sinks from being the sole route burdened with relaying the messages of all of the devices on the network to the sink. This architecture further de nes the role of the bridges to coordinate their local collectors to send data one device at a time, enabling the expansion in network tra c to increase logarithmically with respect to the increase in the number of collectors. HOIST also allows further scaling by using the rst mobile sink, designated as the messenger, to travel between geographically segregated deployment areas to enable each cluster to send their data without having to create unnecessary lines of devices to connect the elds together. Furthermore each of the collectors is designed to locally store all of their data until the messenger next arrives, when it will receive a dump of all collected data before leaving. In this manner, a central data processing facility would be able to send the messenger to each of the remote deployment areas and receive back all of the collected data for processing. Further extending this design, I have added the ability to use a second mobile sink, designated as an observer, to perform live collection on the local cluster it is in, allowing a responsible party to perform a spot-check of the environment. The architectural design required signi cant modi cations to the open-source, commonly used Contiki operating system. These modi cations fall within the guidelines of the routing protocol speci cations and represent un nished aspects of Contiki's implementation. Additional mod cations were also made beyond the protocol speci cation to further allow the operating system the capabilities to properly manage general, multiple-sink… Advisors/Committee Members: Simon, Robert (advisor).

Les réseaux de capteurs sont des réseaux particuliers composés d'objets contraints en ressources. Ils possèdent une faible puissance de calcul, une faible puissance de transmission, une faible bande passante, une mémoire de stockage limitée ainsi qu'une batterie à durée de vie limitée. Afin d'intégrer de tels réseaux dans l'internet des objects, de nouveaux protocoles ont été standardisés. Parmi ces protocoles, le protocole RPL (pour Routing Protocol for Low Power and Lossy Networks). Ce protocole est destiné a construire une topologie logique de routage appelée DODAG. Dans cette thèse, nous abordons l'aspect acheminement de données qui considère une topologie de routage arborescente. L'acheminement des données se fait donc de saut en saut d'un enfant à son parent (ou d'un parent à son enfant). Optimiser la construction du DODAG revient donc à construire un arbre couvrant selon une contrainte donnée. Un arbre couvrant est une structure communicante qui permet de maintenir un unique chemin entre toutes paires de noeuds tout en minimisant le nombre de liens de communication utilisés. De plus, nous considérons les contraintes des réseaux de capteurs telles qu'une batterie déchargée et la variabilité du lien radio comme des fautes transitoires. Ceci nous conduit par conséquent à construire une structure couvrante tolérante aux fautes transitoires. L'auto-stabilisation est une branche de l'algorithmique distribuée qui assure qu'à la suite d'une ou de plusieurs fautes transitoires, le système va retrouver de lui-même un comportement correcte au bout d'un temps fini. L'objectif de cette thèse est de proposer des algorithmes auto-stabilisants dédiés aux réseaux de capteurs.

Spanning Trees from theory to practiceSelf-Stabilizing algorithms and sensor networksAbstract : Sensor networks are composed of ressources constrained equipments. They have low computing power, low transmission power, low bandwidth, limited storage memory and limited battery life.In order to integrate such networks in the Internet of things, new protocols were standardized such as RPL protocol (for Routing Protocol for Low Power and Lossy Networks). This protocol is intended to build a logical routing topology called DODAG (for Destination Oriented Directed Acyclic Graph). In this thesis, we discuss the data routing aspect by considering a tree routing topology. Thus, the routing of data is hop by hop from a child to its parent (or from a parent to its child). Optimize the construction of the DODAG is therefore to build a spanning tree in a given constraint. A spanning tree is a connecting structure that maintains a unique path between all pairs of nodes while minimizing the number of used communication links. Furthermore, we consider the constraints of sensor networks, such as a dead battery and the variability of the radio link as transient faults. This leads us to build a covering structure tolerant to transient faults. The self-stabilization is a branch of distributed algorithms that ensures that following one or more transient faults, the system…

IPv6 Low Wireless Personal Area Networks} (6LoWPAN) é a mais promissora tecnologia para a implementação da chamada Internet das Coisas. Para que esta tecnologia torne-se uma realidade, protocolos de roteamento precisam ser resilientes a variações na qualidade da transmissão, devido a constantes mudanças nos enlaces. O mais promissor destes protocolos é o IPv6 Routing Protocol for Low-Power and Lossy Networks} (RPL). Nesta dissertação, o protocolo RPL é extendido de forma a considerar a incerteza na qualidade dos enlaces. O problema de roteamento do RPL Robusto é modelado como um problema de otimização robusta derivado do Problema da Árvore de Caminhos Mais Curtos, denominado Árvore de Caminhos Mais Curtos Robusta (RSPT). São propostas três heurísticas para o RSPT, além de duas diferentes formulações matemáticas e um algoritmo exato baseado em uma das formulações propostas. Além disso, dois algoritmos aproximativos da literatura para problemas de Otimização Robusta foram extendidos para o RSPT, e uma prova de seus fatores de aproximação foi desenvolvida. Os algoritmos propostos são comparados com os algoritmos da literatura. Experimentos computacionais demonstraram que o algoritmo exato proposto resolveu todas as instâncias propostas com 100 vértices na otimalidade. Entretanto, ele não conseguiu resolver instâncias com 200 vértices na otimalidade em um tempo de 24 horas. Uma das heurísticas propostas apresentou resultados melhores que os algoritmos aproximativos extendidos da literatura, sendo que obteve um gap relativo próximo ao gap do algoritmo exato proposto com um tempo computacional muito inferior. Duas das heurísticas propostas podem ser implementadas como protocolos de roteamento para 6LoWPANs.

IPv6 Low Wireless Personal Area Networks (6LoWPAN) is the most promising technology for implementing the so called Internet of Things. In order for this technology to become a reality, routing protocols need to be resilient to variations in the links quality, due the constantly changes in the channels. The most promising of these protocols is the IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL). In this work, the RPL routing protocol was extended to consider the uncertainty in the link quality. The RPL Robust routing problem is modeled as a Robust Shortest Path Tree problem (RSPT). Three heuristics for the RSPT are developed, besides two different mathematical formulations, and an exact algorithm based on one of the proposed formulations. The proposed algorithms are compared with two algorithms from the literature. One of the proposed heuristics has presented better results that the literature algorithms, and its can be implemented as a routing protocol for 6LoWPANs.
