Abstract In this paper, a novel cooperative routing algorithm is proposed based on a relay selection strategy, where the routing packets on potential relays are exploited to collect the channel state information. Then a distributed algorithm is taken to select the “best” relay from potential relay set with which a cooperative routing protocol is presented for Ad hoc networks. In layered wireless networks, the implementation of relay selection involves time synchronization and crosslayer optimization. The simulative results show that the proposed algorithm outgoes non-cooperative DSDV routing protocol with considerable gain of deliver ratio and latency.
