Abstract

In order to jointly optimize the performance of symbol error rate (SER) and network lifetime (NL) in cooperative communications, an efficient multi-relay selection algorithm (JOMRS) based on statistics channel gain (SCG) and node residual energy (NRE) is put forward. Firstly, this algorithm obtains the pre-selection set of relay nodes from the candidate relay nodes based on SCG. Secondly, it rearranges the relay nodes in the pre-selection set in ascending order according to the values of the weighting function constructed by SCG and NRE to get the optimization set. Finally, for minimizing the average symbol error rate of signal relay, it selects the suitable number of relay nodes L. Thus the selected multiple relays are the first L relays in the optimization set. Simulation results show JOMRS algorithm can achieve better SER performance as well as NL performance than BSRS algorithm, and obtain longer NL than BMRS algorithm.
