M.Comm.

Most modern and even not so modern businesses are currently investing in the hire or purchase of private access branch exchange (PABX) equipment. Usually the main concern is one of reduced costs to the company, since the internal calls between users on the same PABX are not routed via the public telecommunications operator (Telkom) and therefore free of charge [ James, 1997: 17 ]. Larger companies are experiencing the problem that their offices are distributed countrywide. They can install PABX equipment at each regional office, but this will only allow the employees within the regional office to communicate via internal calls. These organisationssoon realise the need for a voice network that provide them with the capability to communicate internally on a country-wide and in some cases, even a worldwide scale. A private voice network can be established by following two routes. If the company is relatively small and cannot afford its own transmission infrastructure in the form of openwire routes. coaxial cables. microwave routes, satellite routes and the associated multiplexers and flexible multiplexers. then they can lease transmission infrastructure from the public telecommunications operator (Telkom) and pay rental and other associated charges for usage thereof If the company can afford the capital investment in its own transmission infrastructure, it will be capable of communicating on a countrywide basis without relying on the service provided by the public telecommunications operator. In most cases, however, the latter option is illegal, due to regulatory protection of the national telecommunications operator. as stipulated by the telecommunications act (103/1996). In some cases, like the Transnet group, legislation requires the use of a private telecommunications network. The reason for this was that a major catastrophe in the transport industry might result due to problems with the telecommunications facilities. In that case, the public telecommunications operator would not accept any responsibility for the consequences of the break in communications. Transtel is the business unit that acts as a "private telecommunications operator" for the Transnet group . Transtel provides both voice and data communications to its clients within the Transnet group . In this case the main concern is not one of reduced costs, and therefore Transtel is implementing a tariff structure similar to that of the public telecommunications operator. The problem of providing voice communications between geographically distributed offices must be solved reliably and efficiently by the private voice network implemented by Transtel to serve the Transnet group. This implies that Transtel have the challenging responsibility to implement a managed voice network, in order to ensure better service levels than can be obtained from Telkom. The next problem that faces the private telecommunications operators for organisations with several business units and a plethora of departments, is that the costs for telecommunications facilities…

▼ The mass-market adoption of high-end mobile devices and increasing amount of video traffic has led the mobile operators to adopt various solutions to help them cope with the explosion of mobile broadband data traffic, while ensuring high Quality of Service (QoS) levels to their services. Deploying small-cell base stations within the existing macro-cellular networks and offloading traffic from the large macro-cells to the small cells is seen as a promising solution to increase capacity and improve network performance at low cost. Parallel use of diverse technologies is also employed. The result is a heterogeneous network environment (HetNets), part of the next generation network deployments. In this context, this thesis makes a step forward towards the “Always Best Experience” paradigm, which considers mobile users seamlessly roaming in the HetNets environment. Supporting ubiquitous connectivity and enabling very good quality of rich mobile services anywhere and anytime is highly challenging, mostly due to the heterogeneity of the selection criteria, such as: application requirements (e.g., voice, video, data, etc.); different device types and with various capabilities (e.g., smartphones, netbooks, laptops, etc.); multiple overlapping networks using diverse technologies (e.g., Wireless Local Area Networks (IEEE 802.11), Cellular Networks Long Term Evolution (LTE), etc.) and different user preferences. In fact, the mobile users are facing a complex decision when they need to dynamically select the best value network to connect to in order to get the “Always Best Experience”. This thesis presents three major contributions to solve the problem described above: 1) The Location-based Network Prediction mechanism in heterogeneous wireless networks (LNP) provides a shortlist of best available networks to the mobile user based on his location, history record and routing plan; 2) Reputation-oriented Access Network Selection mechanism (RANS) selects the best reputation network from the available networks for the mobile user based on the best trade-off between QoS, energy consumptions and monetary cost. The network reputation is defined based on previous user-network interaction, and consequent user experience with the network. 3) Network Reputation-based Quality Optimization of Video Delivery in heterogeneous networks (NRQOVD) makes use of a reputation mechanism to enhance the video content quality via multipath delivery or delivery adaptation.

▼ The proliferation of high-end mobile computing devices (e.g., smartphones, tablets, notebooks and more) equipped with high-speed network access, enables the mobile users to watch multimedia content from any source on any screen, at any time, while on the move or stationary. Moreover, nowadays people tend to spend much of their time consuming multimedia content from various devices with heterogeneous characteristics (e.g., TV screen, laptop, tablet, smartphone, etc.). In order to support uninterrupted, continuous, and smooth video streaming with reduced delay, jitter, and packet loss to their customers, network operators must be able to differentiate between their offerings according to device characteristics, including screen resolution. With the mobile networks migrating towards Long Term Evolution (LTE)-Advanced and all-IP networks, people expect to connect to the Internet anytime, anywhere and from any IP-connected device. Therefore, fast surfing speed on Internet, high resolution display screen, advanced multi-core processor and lasting battery support are becoming significant features in the current mobile devices. In this context, this thesis describes research solutions which help establish an Always Best Experienced heterogeneous environment. The proposed solutions include: (1) a novel Utility-based Priority Scheduling (UPS) algorithm for resource allocation over LTE that considers the mobile device differentiation when providing high quality delivery of multimedia services. The priority scheduling decision is based on the device classification, mobile device energy consumption and multimedia streaming tolerance to packet loss ratio; (2) a Device-Oriented Adaptive Multimedia Scheme (DOAS) for multimedia delivery over LTE networks. DOAS is a cross-layer solution built on top of the downlink scheduler in LTE/LTE-A systems. The adaptation decision in DOAS is based on the end-user device display resolution information and Quality of Service (QoS); (3) an enhanced energy-aware DOAS (eDOAS) to provide an energy efficient interworking solution for LTE -WLAN heterogeneous environments and to prolong the battery lifetime of the mobile devices; and (4) an Evolved Energy-saving QoEaware Device-Oriented Adaptive Scheme (e3DOAS) for balancing energy-consumption of mobile devices and perceptual quality of mobile users and fairly adapting trade-off quality level to users by using coalition game theory based mechanism. A real experimental test-bed for mobile device power measurement was setup to measure the energy consumption of different mobile devices classes while performing Video on Demand (VoD). The impact of the device performance, quality levels of the multimedia stream and the transport protocols on energy consumption is analysed. The performance of the proposed solutions is evaluated using network simulators NS-3, LTE-Sim and Matlab. Advisors/Committee Members: Gabriel-Miro, Muntean, Ramona, Trestian.

Power line communication systems for automatic electricity meter reading which use signals capable of passing through the distribution transformer are attractive because the whole communication channel is utility owned and pre-exists. The performance of current commercial systems is limited to data rates of a few hundred bits per second (bps) which is insufficient for reading interval meters. This thesis addresses the question of whether or not this channel could be used for interval meters. Channel sounding equipment was developed to measure the upstream current transfer ratio and the design of this reliable and portable equipment is presented. It was used to sound six very different channels within La Trobe University's distribution system. The measurements are presented along with the derivation of parametric models of the channels. It is shown that all of the cannels can be represented by one generic type model which is a non-minimum phase system with six zeros and five poles, one of the zeros and one of the poles being fixed and the others varying over limited frequency and damping factor ranges according to the particular channel characteristics. Noise measurements on the medium voltage supply were conducted. These measurements were made in narrow bands across the spectrum of interest. It was shown that, irrespective of the nature of the probability distribution of the wideband noise, measurements within narrow enough bands have close to Gaussian distribution. A method for generating current signals within a meter was demonstrated and an achievable current signal level estimated. This, in combination with the channel models and the noise measurements enabled determination of the Shannon capacity limits for each of the channels. All channels exhibited Shannon limits above 10,000 bps with three of the six channels above 30,000 bps. The implication of this finding is that the channel is suitable for remotely reading interval meters. The thesis is a case study with the assumption is that the la Trobe distribution system is a good representation of utility owned systems but tests to confirm this assumption have not yet been performed. Design of a complete communication system to use the channel for automatic meter reading was not attempted; however, a resonant circuit switched across the mains for meter endpoint signal generation was suggested. Operation of such a transmitter was studied in some detail and the new understanding, missing from existing literature, is presented.

M.Tech. (Computer Science)

The Signal Distribution department of the SABC does planning regarding the signal distribution or broadcasting network of the SABC. In order to do effective planning a tool had to be developed to assist in the planning of the broadcasting network. The Rand Afrikaans University was asked to supply a student to analyze the problems surrounding the development of such a tool and supply the SABC with a solution to the problems. The problems surrounding the development of a broadcast network planning model were the availability and accuracy of the information needed for planning. The data needed was spread throughout the country with only manual means to transport the data. The solution to the problem would be to develop a system to cope with the decentralized database and to gather the data in order to supply valuable planning information. To provide a framework for the solution of the planning problem, a broadcasting network was compared with a computer network. The comparison revealed a number of parallels between a broadcasting and a computer network. As a result of the resemblance between the two types of networks, a foundation for the development of a planning model for a broadcasting network could be identified. The ISO IS OSI approach was used as a foundation for the development of the model. The principles of the seven layers along with the three network management models The broadcasting network model was developed using the principles of the OSI approach, object orientation, geographical information systems and graphical user interfaces. A "package" was defined to assist in the logical data flow of the model. The package contains the specific data used in a calculation. A package containing information can be split or combined according to strict rules. The effective management of the package is a central issue in the development of the planning model. A prototype system was developed on PC-Arc/Info, a PC based GIS. The prototype's aim was to prove that the principles used in the model could be implemented successfully. As the developed system was intended to serve as a prototype, it did not implement the full functionality of the model, but only the functions necessary to prove the viability of the model.

▼ Wireless vehicular communications is a cutting edge set of technologies driven by the vision of providing a suite of original applications, and supported by emerging standards such as IEEE 802.11p. In turn the popularity of these applications is one of the key factors, which will drive the uptake of these vehicular communications technologies and ultimately determine their market success. Applications for vehicular communications can be placed in three main categories - Traffic Safety, Traffic Efficiency and Value-added Services (e.g. Infotainment/Business). Our work focuses on the provision of traffic efficiency services as we believe they offer an immediate benefit and can be adopted quickly by a large number of potential users. Satellite navigation systems provide a ready made deployment platform for these types of services and have already proven popular (14.4 million portable satellite navigation systems sold in Western Europe in 2007). There is also an existing trend toward complementing satellite navigation-related technology with local area wireless communications (by 2013 34% of all portable navigation devices will feature wireless cards 2). Our emphasis is on an infrastructure-based approach as this allows early adopters of wireless enabled satellite navigation devices to receive useful services from day one, regardless of the penetration level of the technology. This thesis describes Smart City, a novel framework, which purposes the use of wireless communication to make city life greener and more efficient. A major contribution to this framework is the proposed intelligent traffic management module. A route management service, which is powered by a best route selection algorithm, is put forward as a prototypical traffic efficiency service for this module. The novel aspect is that the algorithm minimizes journey times and traffic congestion as well as fuel consumption and emissions. Testing has shown how the algorithm provides-shorter journey times, a reduction in fuel consumption and harmful emissions and also results in financial savings. We have proposed and implemented an infrastructure-based communication scheme that enables prioritization of services provided to vehicles. Advisors/Committee Members: Muntean, Gabriel-Miro, IRCSET.

▼ The use of electrical networks for telecommunications has a long history. It has been known since the beginning of the twentieth century [Ahola03]. The idea of using electrical networks for broadband communications arose in the 1990s [Hrasnica et al 04]. Recent and growing research interest has indicated that PowerLine Communications (PLC) is the threshold for achieving broadband delivery particularly in very dispersed and low teledensity areas. Currently, there are numerous PLC trials and commercial deployments underway inside and outside South Africa. Nevertheless, these PLC deployments are very isolated, done without clear methodology and performance remains bound to the physical layout of the electrical network. Because of that high bandwidth broadband PLC systems are prone to poor performance and this in turn limits the acceptance and deployment of this emerging alternative broadband technology. Though, PLC technical challenges are being addressed, there has been little analysis and research work that is focused on the “Development of Methodologies for Deploying and Implementing Local & Medium Area Broadband Power Line in Residential and Office Electric Grids” that would lead to broadband PLC being adopted and be of greater use to non-broadband communities of South Africa. PLC is a term describing several different systems using electrical grid distribution wires for simultaneous distribution of data by superimposing an analog signal [Hrasnica et al 04]. The research proposed and presented broadband PLC methodologies for typical medium voltage and local voltage PLC networks. These methodologieswere implemented and experimented with in configurations which closely mirrored residential and office settings through laboratory and multibuilding experiments using commercial 2nd Generation Mitsubishi Electric PLC technology. Research results presented not only serve to provide insight into broadband PLC but also how it handled broadband applications (communications), competed and compared with other technologies such as Ethernet LAN. In combination with networking communication theories, the research explored and analyzed the extent of PLC in providing broadband communication to residential and office electric grids at the University Fort Hare, Computer Science Department.

In a wireless network, owing to the time-varying nature of wireless channels, different mobile users typically experience peaks and troughs in channel quality at different times. This diversity in channel quality is known as multiuser diversity. With the aid of rate adaptation, multiuser diversity can be exploited by allowing the mobile user with the best channel to use the channel resource. However, in order to achieve this in most practical systems, the mobile users in the network must feed back their channel state information (CSI) to the transmitting user. In large networks, this feedback overhead can outweigh the multiuser diversity gain. In this thesis dissertation, a centralised wireless medium access control (MAC) scheme, namely Multiuser Diversity with Capture (MDC), is discussed as a solution to obviate the overhead problem. MDC explicitly employs the capture effect in radio receivers to reduce network overhead by allowing multiple mobile stations (MSs) with channels better than a nominal response threshold to simultaneously compete for the wireless channel. Owing to the capture effect, the base station (BS) can determine which MS has the best channel. In comparison with the Medium Access Diversity (MAD) scheme in the literature, the proposed MDC possesses the strong merit that the feedback overhead is independent of the number of MSs in the network. Several aspects of the MDC scheme are investigated in detail. An application of the MDC scheme based on the physical layer and parts of the MAC layer of the IEEE 802.11a standard is considered. A general analytical framework for the goodput performance of MDC is derived. Using this framework, the exact closed form solution for the expected goodput of MDC with rate adaptation over Rayleigh fading channels is calculated. The fairness performance of MDC in networks where some MSs experience better average channel conditions than others is also addressed. MSs with low average channel states tend to use the channel less often in MDC than MSs with high average channel states. This issue is tackled with Fairer Multiuser Diversity with Capture (FMDC), a variant of the MDC scheme designed to share the channel resource more equitably across all of the MSs in the network. In FMDC, instead of using the network-wide response threshold to decide whether to compete for the channel, each MS only competes for the channel when their channel state is greater than a threshold factor multiplied by their average channel state. Finally, the problem of adaptive optimisation of the response threshold for MDC and the threshold factor for FMDC is also considered. In the proposed solution, the response threshold and the threshold factor are adapted heuristically according to the estimated goodput performance of the system. The adaptive heuristic has importance in practical systems because the BS usually does not know the characteristics of the time varying channels of the MSs in the network.

In a wireless network, owing to the time-varying nature of wireless channels, different…

▼ This dissertation is focused on multi-service and direct sequence code division multiple access (DS/CDMA) wireless cellular systems. The reverse link performance of a slotted DS/CDMA cellular system with multi-service traffic is analyzed. Services with/without packet retransmission to meet their Quality of Service, share the entire bandwidth. Packet failure probabilities and packet delay are obtained based on analyzing the mutual interaction among services. The impacts of power level allocation and power control error of services on capacity, throughput and delay are analyzed under given Quality of Service. The system capacity is maximized by appropriate power allocation. The impact of power control error on capacity is dependent on whether packet retransmission is allowed or not. Admission control policies for multi-service systems are proposed and analyzed. Both nonprioritized and prioritized admission control are studied. Services difference in terms of resource requirement and degree of importance are considered. Analytical models are developed. Blocking probability of each type of calls are found under given amount of traffic. Fair access by soft capacity is addressed. The cost of protecting certain type(s) of calls on the rest of calls is investigated. The impact of traffic distribution on the performance of the policies is also examined. In a hierarchical cellular system, user mobility estimation helps channel assignment so as to reduce the handoff rate and avoid high mobility users travel among small cells. Two different strategies are compared. It is found that when high mobility users are served by overlay macrocells, call drop rate is reduced. Speed estimation error only has limited impact on the system performance. User membership in a cellular CDMA network is simulated based on the estimation of the local mean value of the pilot signal from surrounding base stations. The base station providing strongest pilot local mean controls the mobile station. Simulation is conducted under different fading environments. Two performance measurements are simulated: the number of membership switchings per second and the probability of wrong base station selection. An optimum window length for filtering out Rayleigh fading is found. Simulation results are in good fit with those of analysis. Advisors/Committee Members: Bhargava, Vijay K. (supervisor).

▼ This thesis provides in-depth information on the high speed optical transport requirements for the Square Kilometre Array. The stringent data rates as well as timing and synchronization requirements are dealt with respect to the optical fibre technology. Regarding the data transport, we draw a clear comparison between a typical telecommunication access network and a telescope network. Invoking simulations and experiments on the field and laboratory test bed, we successfully implement a suitable telescope network using vertical cavity surface emitting laser (VCSEL) technology. Polarization effects on the KAT-7 telescope network, an operational prototype for the SKA is studied so as to estimate the expected effect in the MeerKAT telescope with transmission distances _ 12 km. The study further relates the obtained values to the expected impact on the distribution of the time and frequency reference in the MeerKAT array. Clock stability depends on the differential group delay (DGD) and polarization stability. On a 10:25 km link that includes the riser cable a DGD of 62:1 fs was attained. This corresponds to a polarization mode dispersion (PMD) coefficient of 19:4 fs=km1=2. This is a low PMD value considering telecommunication network. The PMD value is within the allowed budget in the telescope network. However, this may not be the case at longer baselines extending to over 1000 km as expected in SKA 2. The fibre's deployment contribution to the DGD is measured by comparing the deployed fibre to the undeployed of equal lengths. On the 10:25 km deployed single mode fibre, the maximum and mean DGDs measured were 217:7 fs and 84:8 fs respectively. The undeployed fibre of similar type and equal length, gave a maximum and minimum DGDs of 58:6 fs and 36:3 fs respectively. The deployment is seen to increase the maximum and minimum DGDs by factors of 3.7 and 2.3 respectively. This implies that fibre deployment is very critical in ensuring the birefringence is minimized. Polarization fluctuation recorded a maximum of 180o during the 15 hour real time astronomer use of the antenna. To ascertain the contribution of the riser cable, state of polarization (SOP) of the buried section of the single mode fibre in the link was established. A maximum SOP change of 14o over 15 hour monitoring was measured. From the stability realized on the buried section of the fibre, the change in polarization is contributed by the riser cable. The fluctuation in polarization can cause the phase of a clock signal to drift between the birefringent axes by an equal amount corresponding to DGD. We experimentally demonstrate how polarization stabilization can be attained using the polarization maintaining fibre. We also demonstrate the applicability of VCSEL technology in the SKA unidirectional data flow especially for shorter baselines < 100 km. The VCSEL is a low cost light source with attractive advantages such as low power consumption, high speed capabilities and wavelength tuneability. This work entails the use of traditional amplitude modulation…

M.Ing. (Electrical Engineering Science)

In today's rapidly changing technological environment, more and more importance is being attached to producing products as small as possible to save space as well as materials. Systems today use a wide range of signals, from those used to transmit energy, to small signal electronic signals used for control purposes. As these signals are not very compatible, they must each have their own cable harness to prevent unwanted interference between the signals. As a first step to reducing system size, the control signals (or any signal containing information) may be transmitted on the power transmission line, using techniques investigated in this dissertation. Systems using the same conductors for simultaneous energy and data transmission have many applications ranging from high tech systems to low cost rural communication. Examples of systems where this technology can be applied include: (a) distributed high frequency power systems, where switching of remote equipment can be done from a central point; (b) communication and control in harsh environments such as mining complexes, where switching of fans and motors for example can be done from a central point, while a communication network can be established by placing the information signals on the power cables; and (c) flexible manufacturing cells, where robots can be controlled via the power transmission harness. On the other hand, rural communication systems can be realised over the 50 Hz utility transmission network in remote areas. Such a system has the advantage of offering a low cost solution to providing access to communication to a large number of people spread over a large area. The work described In this dissertation covers two systems, firstly information transmission over the 50 Hz utility network and secondly, the design of a high frequency distributed power system utilising simultaneous information transmission on the transmission line.The first three chapters give an introduction to the technology and discuss the theory which must be applied to make simultaneous energy and information transmission over one conductor viable. Chapter 4 discusses the 50 Hz utility network as an information distribution network. The advantages and disadvantages are discussed, while some solutions are proposed how the disadvantages can be overcome. Chapter 5 discusses a high frequency distributed power system using simultaneous information transmission. The converter design is discussed, while some special design considerations are given which are essential to successful simultaneous information transmission in such a distributed system. To help with the design of the converter used, a simulation was carried out to predict the voltage and current waveforms in such a converter, the results of which can be seen in Appendix B.. The aim of simultaneously transmitting energy and information on the same transmission line was realised in both cases. In the 50 Hz system it was shown that adding external networks to guide the information carrier…

▼ Ces dernières années, la popularité croissante de terminaux mobiles de plus en plus intelligents a provoqué une hausse considérable du trafic supporté par les réseaux de télécommunications cellulaires. Dans ce contexte, le déploiement de réseaux dits de quatrième génération basés sur le standard LTE (Long Term Evolution) et offrant des capacités significativement plus élevées que les réseaux de générations précédentes peut sembler être une solution idéale. Cependant, dans le cas d’un service à délivrer à un très grand nombre d’utilisateurs, ce standard, malgré la disponibilité de la technologie eMBMS (Evolved Multimedia Broadcast Multicast Services), n’est pas forcément le plus adapté. Dans le même temps, la télévision a achevé dans de nombreux pays sa transition vers le numérique. L’abandon de la transmission analogique a permis non seulement d’améliorer la qualité du service mais aussi d’occuper moins de spectre. En France, une partie du spectre libéré a déjà été attribué au déploiement de réseaux LTE. Une autre méthode permettant d’exploiter ce spectre au profit des réseaux de communications mobiles est proposée dans cette thèse : le réseau hybride. Le réseau hybride est constitué d’un réseau cellulaire au standard LTE accompagné d’un émetteur DVB-T2 (Digital Video Broadcasting – Second Generation Terrestrial). Les aires de couverture de ces deux composantes se superposent et un service peut être transmis aux utilisateurs présents dans ces aires indifféremment par l’une ou l’autre des composantes. Ce concept permet de pallier un point faible du standard LTE, c’està- dire la capacité à délivrer efficacement un même service à un grand nombre d’utilisateurs simultanément. Après une étude approfondie des deux standards utilisés, un modèle mathématique du réseau hybride est proposé. Ce modèle se base sur les propriétés géométriques du réseau hybride, les performances des deux types de signaux utilisés, et sur plusieurs types de répartition des utilisateurs pour évaluer les performances du réseau hybride selon différents critères. Le premier critère étudié est un critère énergétique. Le modèle proposé permet de comparer les efficacités énergétiques des deux composantes pour transmettre un service en fonction de son nombre d’utilisateurs. L’efficacité de la composante DVBT2 dépasse celle de la composante LTE à partir d’un seuil dont la valeur varie avec les propriétés géométriques du réseau et le type d’affaiblissement de propagation auquel sont soumis les signaux. Il est de plus possible, dans certaines circonstances, d’améliorer encore l’efficacité énergétique du système en utilisant conjointement les deux composantes. Le second critère étudié est celui de l’encombrement du réseau cellulaire. En effet, un service consommé par un grand nombre d’utilisateurs peut avoir un impact conséquent sur le trafic à transmettre par un réseau LTE. Utiliser la composante DVB-T2 pour distribuer un tel service permet de réduire la charge du réseau cellulaire, et ceci même dans le cas où la composante DVB-T2 ne couvre pas l’ensemble de… Advisors/Committee Members: Hélard, Jean-François (thesis director).

▼ Constrained remote state estimation and quickest change detection in the context of Cyber-physical systems are studied in this thesis. The remote state estimation is studied from the perspective of both an estimator and an attacker. Three different problems are formulated, and the common theme is twofold: (i): The resources for the estimator/attacker/decision maker are limited, and efficient resources utilization policies are thus necessary. (ii): In each proposed (optimal) policy, decisions are made sequentially with real-time information. In the remote estimation from the estimator's perspective problem, a sensor observes a dynamic process and sends its observations to a remote estimator over a wireless fading channel characterized by a time-homogeneous Markov chain. The successful transmission probability depends on both the channel gains and the transmission power used by the sensor. Jointly optimal transmission power controller and remote estimator, which minimize an infinite-horizon cost consisting of the power usage and the remote estimation error, are presented by formulating the problem as a partially observable Markov decision process (POMDP). Structural results are provided using the majorization theory when the monitored dynamic system is scalar. The remote estimation from the attacker's perspective is studied in multi-systems scenarios. Suppose there are M independent systems, each of which has a remote sensor monitoring the system and sending its local estimates to a fusion center over a packet-dropping channel. An attacker may generate noises to exacerbate the communication channels between sensors and the fusion center. Due to capacity limitation, at each time the attacker can exacerbate at most N of the M channels. The optimal attack policy, which maximizes the estimation error at the fusion center, is solved as a solution to a Markov decision process (MDP), of which a threshold structure is proved. To overcome the curse of dimensionality of MDP algorithms, we further provide an asymptotically optimal (as M and N go to infinity) policy, which is easy to compute and implement. The quickest change detection problem is to detect an abrupt change event as quickly as possible subject to constraints on false detection. Unlike the classical problem, where the decision maker can access only one sequence of observations, in this thesis work, the decision maker chooses one of two different sequences of observations at each time instant. The information quality and sampling cost of the two sequences of observations are different. We present an asymptotically optimal joint design of observation scheduling policy and stopping time such that the detection delay is minimized subject to constraints on both average run length to false alarm and average cost per sample. The decentralized case in a multi-channel setting is also studied.

▼ The goal of routing in a telecommunications network is to distribute user traffic from in a network of sources and destinations in accordance with the traffic's service requirements and subject to the network's resource restriction. Objectives of routing scheme include maximizing the network performance, such as larger carried load, fewer blockings and fewer crankbacks, while minimizing the cost, such as fewer trunk groups and fewer intermediate tandems. Constraints are imposed by the limitations of trunk resources, user traffic, and the network services provided and user services requested. Mean field and Monte Carlo computer simlutaions programmes are built according to the queueing theory and telecommunication engineering theory. Several traffic processes, such as blockings, crankback and overflow, and a variety of traffic profiles, topologies and structures are under investigation. We also develop a new software package TNSP (Telecom Network Simulation Package) to simulate various traffic conditions of East Kowloon telephone network of Hong Kong. As the network technologies evolve, enhanced routing methods are required to meet the dramatic demand of the growth of telecommunications services. We in-vent a new adaptive and efficient routing technique called Neural Routing to tackle this stochastic and nonlinear optimization problem. We use a simplex-based central-ized algorithm to dynamically distribute telephonic traffic among alternate routes in circuit-switched networks according to the fluctuating number of free circuits and the evolving call attempts. It gives an excellent network performance especially in asymmetric traffic conditions and uneven network configurations. We apply it to gen-erate examples for training localized Neural controllers. Simulations show that the decentralized Neural approach has a significant improvement in blocking probability with Maximum Free Circuit (MFC) which forms the basis of AT&T's Real-Time Net-work Routing (RTNR) and gives a surpassing performance in crankback percentage especially for an unbalanced configuration network with uneven traffic profile.
