Abstract
The paper explores the interaction between cooperative diversity techniques, in the physical layer, and routing, in the network layer. Three approaches are proposed: relay-by-flooding; relay-assisted routing; 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; 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; best-select in the decoded set. Best-select in the decoded set is shown to improve the performance significantly.Keywords
