Abstract

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. In wireless networks where transmitter transmits data over multiple hops and relays can communicate with each other, the relationship between cooperation and channel-adaptive routing is provided in this paper. The cooperation is only helpful if designed combine with a routing technique. However, the routing scheme used for combining with cooperation is very complex and involves large computation overhead. To overcome these problems, optimized link state routing is implemented in this paper. The simulation result shows that the proposed node selection scheme will results in better selection of nodes for cooperative wireless networks.
