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.
Book Synopsis Protocol Design and Analysis for Cooperative Wireless Networks by : Wei Song
Download or read book Protocol Design and Analysis for Cooperative Wireless Networks written by Wei Song and published by Springer. This book was released on 2016-11-03 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the design and analysis of protocols for cooperative wireless networks, especially at the medium access control (MAC) layer and for crosslayer design between the MAC layer and the physical layer. It highlights two main points that are often neglected in other books: energy-efficiency and spatial random distribution of wireless devices. Effective methods in stochastic geometry for the design and analysis of wireless networks are also explored. After providing a comprehensive review of existing studies in the literature, the authors point out the challenges that are worth further investigation. Then, they introduce several novel solutions for cooperative wireless network protocols that reduce energy consumption and address spatial random distribution of wireless nodes. For each solution, the book offers a clear system model and problem formulation, details of the proposed cooperative schemes, comprehensive performance analysis, and extensive numerical and simulation results that validate the analysis and examine the performance under various conditions. The last section of this book reveals several potential directions for the research on cooperative wireless networks that deserve future exploration. Researchers, professionals, engineers, and consultants in wireless communication and mobile networks will find this book valuable. It is also helpful for technical staff in mobile network operations, wireless equipment manufacturers, wireless communication standardization bodies, and governmental regulation agencies.

Book Synopsis A Cooperative Communication Protocol for Wireless Ad-hoc Networks by : Jeremy Isaac Silber
Download or read book A Cooperative Communication Protocol for Wireless Ad-hoc Networks written by Jeremy Isaac Silber and published by . This book was released on 2002 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design and implementation of a communication protocol that utilizes local cooperation among nodes to efficiently transfer data. Multi-hop routing in ad-hoc wireless networks realizes some scalability benefits over direct transmission by utilizing cooperation in the network layer, where all nodes act as routers to relay messages. Cooperative transmission takes this idea a step further, moving cooperation to the link layer, where nodes actually broadcast signals simultaneously to increase signal strength. Using network topology information derived from propagation delay measurement, nodes dynamically establish and update membership in rebroadcasting cells. Rebroadcast cells use constructively interfering modulation schemes to broadcast radio signals together, directing an amplified signal toward the intended recipient. This results in a link-layer routing system well suited to real-time data streaming in mobile, ad-hoc, wireless networks.
