Cooperative devices are receiving greater focus in wireless communication as they substantially enhance system performance by decreasing power consumption and packet loss rate, while also increasing system capacity and network resilience. Providing the vital background information needed for those involved with the development and implementation of cooperative mechanisms, this volume introduces key cooperative strategies for infrastructure-based systems, as well as for self-organizing, multi-hop networks. Providing a key reference for researchers and product developers, the text details those recent improvements in a variety of cooperative mechanisms and frameworks that are applicable in diverse scenarios.
