Power Efficient Decode-and-Forward Cooperative Relaying
Zhengguo Sheng, Bong Jun Ko, Kin Kwong Leung · IEEE Wireless Communications Letters · 2012
Cooperative communications have been proven to be effective in enhancing performance of wireless networks. In this letter, we introduce and propose adaptive relay-selection rules to offer a tradeoff between fairness and energy consumption at each node for a network with multiple, mutually cooperative nodes. Our performance analysis is supplemented by simulation results to illustrate the significant energy savings of the proposed optimal power allocation and the relay-selection rules.
