Abstract :
In order to optimize the performance of cooperative communication system, it presents a dynamic multi-relay amplify forwarding (AF) cooperation node selection algorithm, considering jointly the residual energy information of nodes and channel state information(CSI) to optimize network lifetime. Theoretical analysis and 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%, and it will effectively improve the system channel capacity.
