摘要 为保证认知无线网络路由的稳定性,减少信道切换次数,降低端到端时延,提出基于信道选择的路由协议。以信道可用概率和信道切换时延为信道选择标准,在确保信道可用的前提下,选择端到端时延最短的路由进行数据传输,提高路由的时延性能和数据投递率。仿真结果表明,与TDRP、PUC-JRCA协议相比,该协议在数据包传输时延、数据投递率方面有明显改善。 In order to ensure the stability of cognitive radio network routing,reduce the number of channel switching and decrease end-to-end delay,a routing protocol based on joint channel selection is proposed.The protocol takes channel availability and switching delay as channel selection criteria.On the premise of ensuring channel availability,it chooses the shortest end-to-end delay route for data transmission to improve the delay performance and data delivery rate of routing.Simulation results show that the proposed protocol has a better performance in terms of packet switching delay and data delivery rate compared with TDRP and PUC-JRCA protocol.
