Abstract :
Next generation wireless networks are expected to provide services which require high performance and reliability. However, channel conditions in wireless networks can affect both throughput and reliability. Cooperative communication has the advantage of offering throughput enhancement and reliability in wireless networks by using several single-antenna nodes to form a virtual antenna array. The performance in cooperative communication depends on the relay selection scheme. Therefore, in this paper, we propose and evaluate a distributed relay-selection scheme based on the channel conditions of candidate relay nodes. Results show that our proposed-relay selection scheme increases the system throughput.
