Cooperative communication allows several nodes to cooperatively
transmit signals to a particular destination. Using cooperative
communication, wireless networks could mitigate severe channel
impairments arising from multipath propagation. In this case, the
greater benefits are gained by exploiting spatial diversity in the
channel. In this book, an overview on cooperative communication in
wireless networks is presented. Practical issues and challenges in
cooperative communication are identified. Cooperative routing
strategies in different networks (wireless mesh networks, ad hoc
networks and wireless sensor networks) are discussed. However,
cooperative routing strategy in a network with multiple flows may
cause collision among helping nodes and thus, reduce the overall
system performance. In this book, a new routing protocol based on
new routing metric called Contention Sensitive Cooperative Metric
(CSCM) is discussed, which takes contention relationship into
consideration. Finally, the performance of the routing protocol has
been evaluated using simulation. The results demonstrate
significant performance improvement of cooperative communication
while using CSCM.
