This book was released on 2018 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-orthogonal multiple access (NOMA) has been considered as an essential enabling technology for fifth generation (5G) and beyond 5G (B5G) cellular networks to meet the increasing demands on low latency, high reliability, massive connectivity, improved fairness, and high throughput. Cooperative relay networks, on the other hand, have been shown to significantly improve the throughput, coverage, and achievable rates of wireless networks, in which, the relay nodes assist the communication between the source node and the destination node when the direct channel is poor. There has been extensive research on the subject of NOMA and cooperative relay networks. However, most of the existing research relies on two main assumptions: flat fading channels and perfect channel state information (CSI) at the transmitting nodes. Instead of those idealistic assumptions, we study NOMA in cooperative relay networks under practical assumptions: frequency selective multipath fading channels and statistical CSI at the transmitting nodes. This dissertation begins with an overview of the basic concept of NOMA. Then, it focuses on downlink NOMA transmissions in a cooperative relay network. Specifically, a base station communicates with two paired mobile users simultaneously via superposition coded orthogonal frequency division multiplexing (OFDM) transmissions with the help of a half-duplex relay under either the decode-and-forward (DF) or amplify-and-forward (AF) scheme, where the power splitting between two mobile users depends on the statistical CSI. We derive the ergodic rates under Rayleigh fading channels and present an ad-hoc approach to determine the power splitting parameters when the target data rates are given. After that, this dissertation presents uplink NOMA transmissions in a cooperative relay network. Specifically, two users, a near user and a far user, communicate with a base station at the same time with existence of a half-duplex relay employing the DF scheme to assist the far user. At the transmitting nodes, the power allocation factors are decided based on the statistical CSI while, at the receiving nodes, the effect of imperfect successive interference cancellation (SIC) implementation is taken into account. Under Rayleigh fading channels, we derive the exact ergodic rate for the near user and the upper bound of the ergodic rate for the far user, then present an ad-hoc approach to determine the power allocation factors when the target data rates are given, and we study the outage probability of the two users at the base station. The last part of this dissertation extends the study into an energy harvesting cooperative wireless sensor network. We consider a two-hop network consisting of a source, two parallel half-duplex relay nodes, and two destinations. While the destinations have adequate power supply, the source and relay nodes rely on harvested energy for data transmission. Different from all existing works, the two relay nodes can also transfer their harvested energy to each other via energy conferencing channels. For such a system, an optimization problem is formulated with the objective of maximizing the total data rate and conserving the source and relay transmission energy.

Download or read book Cooperative Protocols in Dense Wireless Networks for Broadcast and Consensus written by Shrut Kirti and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Network congestion is a communication bottleneck in large wireless networks which use packet-switched communications, impeding their performance in critical applications like network broadcast and in-network data processing. This forms the motivation for this thesis. We propose low complexity physical layer communication protocols that use cooperative transmission to ameliorate this problem. We show that cooperation at the physical layer can significantly improve performance with relatively small coordination overheads by exploiting the broadcast nature of the wireless channel. In the first part of the thesis, we address congestion in broadcast and propose decode and forward protocols that can accommodate multiple users broadcasting their content simultaneously. These protocols incorporate state of the art techniques like power control, successive interference cancellation, use of sideinformation for decoding, and interference alignment. By considering the two user linear network in depth we obtain the necessary conditions for the successful broadcast of the content of multiple users. It is shown that these physical layer cooperative protocols achieve lower broadcast latency than packet-switched flooding protocols and are suitable for broadcast in environments with fading. Additionally, we examine the performance of single user broadcast in the presence of decoding errors and show that the errors in its information flow need not be catastrophic. Supporting numerical results are included. In the second part of the thesis, we employ a similar approach and propose an efficient physical layer architecture for average consensus gossiping algorithms which perform in-network computation. This architecture relies on structured codes which combine channel and source coding. These codes result in consensus updates that are data driven, where transmissions are scheduled based on the states of the nodes rather than their index. Through this simple strategy we show that in spite of bandwidth and power limitations, nodes in an increasingly dense network can converge to the average with bounded delay and precision. Simulations show that this strategy outperforms packet-switched protocols even for moderately sized networks.

This book was released on 2012-12-14 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades, we have witnessed unprecedented innovations in the development of miniaturized electromechanical devices and low-power wireless communication making practical the embedding of networked computational devices into a rapidly widening range of material entities. This trend has enabled the coupling of physical objects and digital information into cyber-physical systems and it is widely expected to revolutionize the way resource computational consumption and provision will occur. Specifically, one of the core ingredients of this vision, the so-called Internet of Things (IoT), demands the provision of networked services to support interaction between conventional IT systems with both physical and artificial objects. In this way, IoT is seen as a combination of several emerging technologies, which enables the transformation of everyday objects into smart objects. It is also perceived as a paradigm that connects real world with digital world. The focus of this book is exactly on the novel collective and computational intelligence technologies that will be required to achieve this goal. While, one of the aims of this book is to discuss the progress made, it also prompts future directions on the utilization of inter-operable and cooperative next generation computational technologies, which supports the IoT approach, that being an advanced functioning towards an integrated collective intelligence approach for the benefit of various organizational settings.
