摘要
Cooperative communication can provide spatial diversity against fading in wireless networks by sending a message to a destination by a source to a relay node. A centralized relay selection scheme with decode-and-forward protocol is proposed based on the wireless network containing multiple source nodes and relay nodes. The relay node that can minimize the total transmission power under the outage constraint of the system is selected by selecting rows and columns of the matrix which is applicable to multiple source nodes networks. The results show that this scheme can reduce the total transmission power effectively, especially when the network contains not so many source nodes and a strict system outage probability is demanded.
