For optimizing the performance of cooperative communication system, it presents a multi-relay amplify forwarding (AF) and decoded forwarding (DF) cooperation node selection algorithm based on the residual energy, considering jointly the residual energy information of nodes and channel state information(CSI) to optimize network lifetime, using the weighting function to select the relay set. Simulation results show that, for dynamic relay power distribution, performance has reached the best while selecting 4 relays. Under the same number of relay, comparing with only considering the channel state information relay selection algorithm, our algorithm extends network lifetime up to 82% for AF protocol, and up to 34% for DF protocol, it all effectively improve the system channel capacity.
