Available in PDF, EPUB and Kindle. Book excerpt: The design of efficient algorithms using cooperation has gained much attention as an emerging technique for the next-generation wireless system. Such a cooperative system allows wireless devices to communicate with each other over relaying. With astute cooperative algorithms, wireless systems are expected to increase sum-rate performance and to support reliable communication. In general, wireless systems can be classified into centralized cellular infrastructures and decentralized ad-hoc multi-hop networks. Cellular networks require high quality channel information to increase sum-rate performance. However, due to finite-rate feedback channels, the base station cannot obtain uncorrupted channel information from mobile stations (MSs), thereby preventing the improvement in the sum-rate performance. On the other hand, multi-hop networks also require high level credit information about neighbor nodes to support reliable communication. Otherwise, traffic is likely to stop at some selfish nodes while being relayed to the destination. The first part of this thesis is motivated with the challenging issue: saving the number of feedback bits while maintaining sum-rate performance. To achieve the objective, this work exploits the cooperation between MSs, known as conferencing, in addition to feedback channels. It has been theoretically shown that cooperating encoders increase the capacity region in multiple-access channels. Similarly, the increase of achievable rate region in broadcast channels with cooperating decoders has been also revealed. In practical systems, the feedback rate is finite as well as cooperation is imperfect. Therefore, it is essential to exploit both cooperation and feedback effectively. Moreover, when multiple MSs are considered, multi-user diversity can be also exploited as yet another independent resource. Using these resources, i.e., feedback, cooperation and user-selection, available in broadcast channels, this thesis introduces the enhancement of the sum-rate performance through rigorous investigation of the relation among the resources. Moreover, this work derives the requirement for the number of feedback bits that achieve the multiplexing gain. Simulation results are presented to evaluate the sum-rate and to verify the derivation. The second part of this thesis focuses on multi-hop networks where each node operates independently without any centralized base stations. This multi-hop network can use cooperation among nodes to increase the total throughput with respect to a single-hop network. However, each node is autonomous and selfish in nature, and thus spontaneous cooperation among nodes is challenged. To accommodate this otherwise selfish nature of multi-hop networks, this thesis proposes a cooperative relay strategy under an energy-limited condition with a game-theoretic perspective. The main focuses are 1) to motivate each node to be cooperative, 2) to decide optimally the amount of cooperation, 3) to analyze equilibrium for the proposed scheme, and thus 4) to maximize the overall throughput. The proposed scheme formulates a Stackelberg game where two nodes sequentially bid their willingness weights to cooperate for their own benefit. Accordingly, all the nodes are encouraged to be cooperative only if a sender is cooperative and alternatively to be non-cooperative only if a sender is non-cooperative. This selective strategy changes the reputations of nodes depending on the amount of their bidding at each game and motivates them to maintain a good reputation so that all their respective packets can be treated well by other relays. Thus, every node forwards other packets with higher probability, thereby achieving a higher overall payoff.

Available in PDF, EPUB and Kindle. Book excerpt: We study secret communication over the discrete memoryless multiple-access channel with the following cooperation strategies: (i) degraded message sets, (ii) a common message, (iii) conferencing, (iv) cribbing, (v) feedback, and (vi) generalized feedback. For developing strong secrecy results, we utilize the methods and techniques of channel resolvability, which involves the characterization of the amount of randomness required at the inputs of the channel to approximately produce a chosen i.i.d. output distribution. For the multiple-access with degraded message sets, a common message, conferencing and feedback, we exactly characterize the channel resolvability region. For the multiple access channel with cribbing, we exactly characterize the channel resolvability region for the causal cribbing and non-causal cribbing scenarios. For the strictly-causal cribbing scenario, inner and outer bounds are provided. For the multiple-access channel with generalized feedback, we provide two inner bounds representing the role of decoding and randomness extraction, which can also be combined. Finally, leveraging the resolvability results, we derive achievable strong secrecy rate regions for each of the cooperation scenarios.

This book was released on 2010-07-28 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cooperative and relay communications have recently become the most widely explored topics in communications, whereby users cooperate in transmitting their messages to the destination, instead of conventional networks which operate independently and compete among each other for channel resources. As the field has progressed, cooperative communications have become a design concept rather than a specific transmission technology. This concept has revolutionized the design of wireless networks, allowing increased coverage, throughput, and transmission reliability even as conventional transmission techniques gradually reach their limits. Cooperative and relay technologies have also made their way toward next generation wireless standards, such as IEEE802.16 (WiMAX) or LTE, and have been incorporated into many modern wireless applications, such as cognitive radio and secret communications. Cooperative Communications and Networking: Technologies and System Design provides a systematic introduction to the fundamental concepts of cooperative communications and relays technology to enable engineers, researchers or graduate students to conduct advanced research and development in this area. Cooperative Communications and Networking: Technologies and System Design provides researchers, graduate students, and practical engineers with sufficient knowledge of both the background of cooperative communications and networking, and potential research directions.
