Abstract

This paper explores the interaction between cooperative diversity techniques in the physical layer and routing in the network layer. Three approaches have been proposed: relay-by-flooding, relay-assisted routing, and relay-enhanced routing. In relay-by-flooding, the tradeoff between achieved rate and required power is studied for three selective decode-and-forward schemes: simple relay, space-time-coded relay, and best-select relay. In relay-enhanced routing, cooperation is applied to each link of an existing route. Two relay selection approaches are proposed: best-select in the neighbor set and best-select in the decoded set. Best-select in the decoded set is shown to improve the performance significantly. © 2004 IEEE.
