摘要 该文提出了一种新的中继选择的协作路由算法,该算法利用网络的路由包获得信道的信息,通过分布式计算从候选中继集合中选择出一个最佳中继转发数据。在分层的无线网络中,中继选择的实现包括了时间同步和跨层优化等。仿真结果表明,相对于DSDV协议,该文所提出的算法有效地提高了数据包的递交率并有效地降低了网络的时延。 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 ＇%est＂ 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.
