Selfishness-aware energy-efficient cooperative networks

In wireless communication, signal fading caused by multi-path propagation is a particularly serious channel detriment. In order to address this issue, cooperative communication mechanisms [1, 73, 74] have been proposed as an effective way of exploiting spatial diversity to improve the quality of wireless links. By encouraging single-antenna devices to share their antennas cooperatively, a number of potential benefits can be achieved, including improved reception reliability [75], reduced power consumption [76], and increased spectrum efficiency [77].
