Performance on Adaptive Path Selection Scheme for Cooperative Communication Networks

In future communications, cooperative communication with relay networks will be the one of the most effective scheme to enlarge coverage area and to boost data rate. In the recent research results, the path selection, power allocation and relay protocols on relay networks are the most important factors to improve the system performance. However, the channel quality of direct transmission path and the relay path will be the influential effect on the performance of relay networks. Therefore, in this paper, we proposed an adaptive path selection (APS) scheme to effectively select the optimal path for cooperative communications.
