摘　　要：在Ad Hoc网络中,利用位置信息可以提高路由协议的性能,但目前的基于位置的路由协议主要是在单信道模型下设计的。为了利用多信道的优势,给出了一个综合利用位置信息和多信道模型的路由协议。该路由协议主要思想是用一个信道接收数据,另外一个信道发送数据,减少包传递时延迟。仿真结果表明,给出的路由协议在平均传包率、平均端到端时延以及汇聚吞吐量方面均优于基于单信道和位置信息的路由协议。In Ad Hoc network,geographic position information can improve the performance of routing protocol,but at present the position-based routing protocols are mainly designed based on single channel model.In order to utilise the advantage of the multi-channel,a routing protocol which comprehensively uses the geographic position information and multi-channel model is brought out in the paper.The main idea of the routing protocol is that to use one channel to receive data packet whilst to use another channel to send data packets simultaneously to reduce the delay of packet transmission.Simulation results reveal that the new routing protocol proposed in the paper performs better than the routing protocols based on single channel model and geographic position information in terms of average successful delivery ratio,average end-to-end delay and aggregate throughput.
