A Modified Node Selection Scheme for Cooperative Wireless Networks

Cooperative relaying is an emerging technology that can compensate for the effects of multipath fading and shadowing by employing multiple relay nodes between sources and destinations. It has the potential to provide reliable transmission, high throughput, and broad coverage, thus drawing great attention in recent years. This paper proposes a node selection scheme in cooperative wireless networks. In a single-hop network with multiple relays, selecting a single node to aid in the transmission between a source and a destination outperforms both traditional orthogonal transmissions and distributed space-time codes. The usage of multiple hops will further improve the wireless communication.
