Available in PDF, EPUB and Kindle. Book excerpt: Cooperative diversity has emerged as a promising technique to combat fading and improve reliability in a wireless environment. In cooperative diversity protocols, neighboring nodes act as virtual multiple-input-multiple-output (VMIMO) systems, where they cooperate with the transmitter-receiver pair to deliver multiple copies of a packet to the receiver via spatially independent fading channels. These multiple copies of the same packet can be combined at the receiver to recover the original packet. Medium Access Control (MAC) protocols play an important part in realizing this concept by effectively coordinating handshake and transmissions between source, partner and destination nodes. In this thesis, we investigate opportunities for improving reliability in Wireless Sensor Networks using cooperative MAC protocols. First, a Medium Access Control protocol, called CPS-MAC, is proposed. Design challenges such as efficiently waking up neighborhood nodes, minimizing energy overhead, and partner selection are also addressed. Then, Reliable Cooperative Transmission-MAC (RCT-MAC) is proposed which extends the functionality of Cooperative Preamble Sampling-MAC (CPS-MAC) by implementing the Cooperation on Demand concept: nodes cooperate only when needed. Furthermore, RCT-MAC is one of the first attempts to compare the performance of a cooperative Wireless Sensor Network (WSN) MAC protocol against conventional protocols for WSNs namely B-MAC, L-MAC, and IEEE 802.15.4. The reliability vs energy efficiency tradeoff is analyzed for both CPS-MAC and RCT-MAC. Lastly, we evaluate a Packet Error Prediction scheme particularly envisioned for preamble sampling cooperative protocols and meant to supplement traditional partner selection schemes. The correlation between the handshake packets and data packets is analyzed using empirical data. ; eng

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.

Available in PDF, EPUB and Kindle. Book excerpt: Today, many wireless networks are single-channel systems. However, as the interest in wireless services increases, the contention by nodes to occupy the medium is more intense and interference worsens. One direction with the potential to increase system throughput is multi-channel systems. Multi-channel systems have been shown to reduce collisions and increase concurrency thus producing better bandwidth usage. However, the well-known hidden- and exposed-terminal problems inherited from single-channel systems remain, and a new channel selection problem is introduced. In this dissertation, Multi-channel medium access control (MAC) protocols are proposed for mobile ad hoc networks (MANETs) for nodes equipped with a single half-duplex transceiver, using more sophisticated physical layer technologies. These include code division multiple access (CDMA), orthogonal frequency division multiple access (OFDMA), and diversity. CDMA increases channel reuse, while OFDMA enables communication by multiple users in parallel. There is a challenge to using each technology in MANETs, where there is no fixed infrastructure or centralized control. CDMA suffers from the near-far problem, while OFDMA requires channel synchronization to decode the signal. As a result CDMA and OFDMA are not yet widely used. Cooperative (diversity) mechanisms provide vital information to facilitate communication set-up between source-destination node pairs and help overcome limitations of physical layer technologies in MANETs. In this dissertation, the Cooperative CDMA-based Multi-channel MAC (CCM-MAC) protocol uses CDMA to enable concurrent transmissions on each channel. The Power-controlled CDMA-based Multi-channel MAC (PCC-MAC) protocol uses transmission power control at each node and mitigates collisions of control packets on the control channel by using different sizes of the spreading factor to have different processing gains for the control signals. The Cooperative Dual-access Multi-channel MAC (CDM-MAC) protocol combines the use of OFDMA and CDMA and minimizes channel interference by a resolvable balanced incomplete block design (BIBD). In each protocol, cooperating nodes help reduce the incidence of the multi-channel hidden- and exposed-terminal and help address the near-far problem of CDMA by supplying information. Simulation results show that each of the proposed protocols achieve significantly better system performance when compared to IEEE 802.11, other multi-channel protocols, and another protocol CDMA-based.

This book was released on 2013 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a new cooperative transmission scheme based on the data exchange between relays (fDSTC) is proposed. Thorough comparisons of this fDSTC protocol and more classical distributed space-time codes (cDSTC) protocols in case of non-regenerative relays (NR-relays) and regenerative relays (R-relays) are considered in terms of error performance, outage probability, diversity order and energy consumption via both numerical simulations and mathematical analysis. In addition, the fDSTC protocol is applied to multi-antenna systems and shown to be more energy-efficient than the cDSTC protocol using either a typical energy model widely-used in the literature or a realistic energy model based on the PowWow platform. Besides, a mathematical analysis in terms of energy consumption is complementarily given to show how to choose the best cooperative models to prolong the lifetime of WSNs. As MAC protocols have a great influence on the total energy consumption of the networks, that leads to a big motivation to design a cooperative MAC protocol, RIC-MAC, by combining preamble sampling and cooperative relay techniques. The analytic results still confirm the interest of using cooperative relay techniques, but their energy efficiency may be affected by the MAC protocol design, the traffic loads of the networks and the desired latency.

Available in PDF, EPUB and Kindle. Book excerpt: Adaptive techniques play a key role in modern wireless communication systems. The concept of adaptation is emphasized in the Adaptation in Wireless Communications Series through a unified framework across all layers of the wireless protocol stack ranging from the physical layer to the application layer, and from cellular systems to next-generation wireless networks. Adaptation and Cross Layer Design in Wireless Networks is devoted to adaptation in the data link layer, network layer, and application layer. The book presents state-of-the-art adaptation techniques and methodologies, including cross-layer adaptation, joint signal processing, coding and networking, selfishness in mobile ad hoc networks, cooperative and opportunistic protocols, adaptation techniques for multimedia support, self –organizing routing, and tunable security services. It presents several new theoretical paradigms and analytical findings which are supported with various simulation and experimental results. Adaptation in wireless communications is needed in order to achieve high capacity and ubiquitous communications. The current trend in wireless communication systems is to make adaptation dependent upon the state of the relevant parameters in all layers of the system. Focusing on simplified cross layer design approaches, this volume describes advanced techniques such as adaptive resource management, adaptive modulation and coding, 4G communications, QoS, diversity combining, and energy and mobility aware MAC protocols. The first volume in the series, Adaptive Signal Processing in Wireless Communications (cat no.46012) covers adaptive signal processing at the physical layer.

This book was released on 2005 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: For WSNs, a theoretical framework is proposed that quantifies the significant gains in network performance due to cooperative diversity. Specifically, theory is presented to model routing behavior and cooperative relay selection, using this information to predict the energy consumption and lifetime of the network. This thesis considers the issue of cooperative diversity in two types of wireless networks, wireless sensor networks (WSNs) and wireless ad hoc networks (WAHNs). Analysis in previous works have shown that cooperative diversity increases energy efficiency in 3- and 4-node networks. The contribution of this thesis is extending the analysis to more realistic network settings. For WAHNs, since forwarding packets for others is not voluntary, a pricing system is proposed to stimulate the use of cooperative diversity in such networks. The goal of the pricing system is to induce forwarding in which all members of the network benefit and in situations where it is intuitively reasonable.
