1. Guo, Jing. Stochastic Geometry for Modeling, Analysis and Design of Future Wireless Networks .

Degree: 2016, Australian National University

This thesis focuses on the modeling, analysis and design of future wireless networks with smart devices, i.e., devices with intelligence and ability to communicate with one another with/without the control of base stations (BSs). Using stochastic geometry, we develop realistic yet tractable frameworks to model and analyze the performance of such networks, while incorporating the intelligence features of smart devices. In the first half of the thesis, we develop stochastic geometry tools to study arbitrarily shaped network regions. Current techniques in the literature assume the network regions to be infinite, while practical network regions tend to be arbitrary. Two well-known networks are considered, where devices have the ability to: (i) communicate with others without the control of BSs (i.e., ad-hoc networks), and (ii) opportunistically access spectrum (i.e., cognitive networks). First, we propose a general algorithm to derive the distribution of the distance between the reference node and a random node inside an arbitrarily shaped ad-hoc network region, which helps to compute the outage probability. We then study the impact of boundary effects and show that the outage probability in infinite regions may not be a meaningful bound for arbitrarily shaped regions. By extending the developed techniques, we further analyze the performance of underlay cognitive networks, where different secondary users (SUs) activity protocols are employed to limit the interference at a primary user. Leveraging the information exchange among SUs, we propose a cooperation-based protocol. We show that, in the short-term sensing scenario, this protocol improves the network's performance compared to the existing threshold-based protocol. In the second half of the thesis, we study two recently emerged networks, where devices have the ability to: (i) communicate directly with nearby devices under the control of BSs (i.e., device-to-device (D2D) communication), and (ii) harvest radio frequency energy (i.e., energy harvesting networks). We first analyze the intra-cell interference in a finite cellular region underlaid with D2D communication, by incorporating a mode selection scheme to reduce the interference. We derive the outage probability at the BS and a D2D receiver, and propose a spectrum reuse ratio metric to assess the overall D2D communication performance. We demonstrate that, without impairing the performance at the BS, if the path-loss exponent on cellular link is slightly lower than that on D2D link, the spectrum reuse ratio can have negligible decrease while the average number of successful D2D transmissions increases with the increasing D2D node density. This indicates that an increasing level of D2D communication is beneficial in future networks. Then we study an ad-hoc network with simultaneous wireless…

Degree: 2019, Pontifical Catholic University of Rio de Janeiro

[pt] Neste trabalho, limites para a densidade de fluxo de potência equivalente produzida pelos lances de descida de sistemas de satélites nãogeoestacionários (não-GEO), operando na faixa de 3,7-4,2 GHz, são analisados. Estes limites visam proteger os receptores do Serviço Fixo por Satélite (FSS) das interferências produzidas por sistemas de satélites não geoestacionários, quando ambos operam na faixa de frequências considerada. A analise destes limites foi motivada pela Resolução 157 da Conferência Mundial de Radiocomunicações de 2015 (WRC-15), que ressalta a necessidade de estudos envolvendo aspectos técnicos e operacionais relativos à operação de sistemas não-GEO operando na faixa de frequências de 3,7 - 4,2 GHz de modo a permitir que esses sistemas possam operar nestas faixas de frequências assegurando, ao mesmo tempo, que os serviços primários existentes, entre eles o FSS, continuem protegidos. A importância do assunto fez com que este tópico fosse incluído na agenda da WRC-19. No trabalho, é inicialmente desenvolvida uma metodologia para a determinação de máscaras limitantes para a densidade de fluxo de potência equivalente produzida pelos lances de descida (epfd(descida)) de sistemas de satélites não-GEO. Esta metodologia foi utilizada na obtenção de duas máscaras baseadas, respectivamente, nos critérios de proteção das recomendações ITU-R S.1323 e ITU-R F.1495. Uma análise comparativa das máscaras de epfd(descida) obtidas foi feita considerando-se cinco constelações de satélites não-GEO do tipo Walker Delta, escolhidas adequadamente para cobrir um amplo conjunto de possibilidades. A análise utilizou, como base, o comportamento estatístico das margens associadas a cada uma das máscaras de epfd(descida) propostas.

[en] In this work, the limits for the equivalent power-flux density produced by the down-links of non-geostationary satellite systems (non-GSO), operating in the 3,7-4,2 GHz band are analyzed. These limits aim the protection of Fixed-Satellite Service (FSS) receivers, from the interferences produced by non-geostationary satellite systems, operating in the same frequency band. The analysis of these limits was motivated by Resolution 157 of the 2015 World Radiocommunication Conference (WRC-15), that recognized the need for studies on technical and operational aspects related to the operation of non-GSO systems operating in the 3,7-4,2 GHz frequency band, so that these systems can adequately operate in these frequency band while ensuring, at the same time, that the existing primary services, among them the FSS, remain protected. Due to its importance the topic was included in the agenda of the WRC-19. In this work, a methodology for the determination of limiting masks for the equivalent power-flux density generated by the down-links (epfd(down)) of non-GSO satellite systems is initially developed. This methodology was used to obtain two mask based, respectively, on the protection criteria of the ITU-R S.1323 and ITU-R F.1495 recommendations. A comparative analysis of the two obtained epfd(down) masks…

3. Do, Minh-Tien. Ultra-narrowband wireless sensor networks modeling and optimization : Modélisation d'un réseau sans fils en bande ultra étroite et optimisation du protocole de communication.

Degree: Docteur es, Télécommunications, 2015, INSA Lyon

Cette thèse a pour but de modéliser les réseaux de capteurs sans fil à faible débit (WSN) basés sur la technique ultra bande étroite. Ce réseau a déjà été déployée par la société SIGFOX et a déjà démontré sa très grande efficacité pour les applications pour l’Internet des objets (IoTs) grâce à sa capacité de communication point à point efficace en terme de puissance consommée, et de sa connectivité de longue portée. Cette étude donne quelques aperçus sur le passage à l’échelle de la technique de l’UNB pour un réseau multipoint à point pour une liaison montante. L’accès au canal spécifique qui est basé sur l’accès multiple par répartition aléatoire de fréquence et de temps (R-FTDMA) est introduit et analysé. En outre, l’impact de l’interférence due à l’absence de stratégie d’ordonnancement à la couche MAC est étudié et modélisé. Notre modèle simplifié nous permet non seulement de décrire la puissance d’interférence agrégée, mais aussi d’évaluer les performances du système d’un tel réseau en matière de taux d’erreur et de probabilité de coupure. De même, la géométrie stochastique est utilisée pour modéliser la distribution spatiale des noeuds afin d’étendre le modèle simplifié dans le canal réaliste où les dégradations de canal sont prises en compte. De plus, le mécanisme de retransmission est considéré pour ce réseau. Cette étude permet de d’identifier le nombre optimal de retransmissions. Le réseau peut être configuré avec un paramètre global unique. Et enfin, cette thèse met en évidence le fait que le réseau de l’UNB Random-FTDMA est très pertinent dans un réseau réaliste, en particulier pour les applications à faible débit, car il allége le coût élevé du réseau, le coût de la synchronisation globale, mais sans perte de performance.

This thesis aims at modeling the low-throughput wireless sensor networks (WSNs) based on ultra-narrow-band technology. Such wireless network is already been deployed by Sigfox company and has proved to be ultra-efficient for the Internet of things (IoTs) applications thanks to its ability of point-to-point communication in terms of power efficiency and long range connectivity. In particular, this thesis gives some insights on the scalability of UNB technology for a multi-point-to-point network in an uplink scenario. The multiple access schemes based on random time and frequency selection are introduced and analyzed. Furthermore, the interference impact due to the lack of scheduling strategy at the MAC layer is studied and modeled. Our simplified model using rectangular function allows us not only to describe the aggregate interference power but also evaluate the system performance of such network in terms of the bit-error-rate and outage probability. Besides, the geometry stochastic is used for spatial node distribution in order to extend the simplified model in the realistic channel communication where the channel impairments are taken into account. Besides, the retransmission mechanism is considered for such network. This study argues an optimal number of retransmission. The network…
