摘　　要：移动Ad Hoc网络是由若干个移动节点构成的无线网络。节点移动和无线传输环境给移动Ad Hoc网络的数据传输提出了挑战。为此,提出基于链路连通时间的移动Ad Hoc网络路由(Link Expiration Time-based routing protocol in Mobile Ad Hoc Networks,LET-RP)。先利用节点移动信息和信道衰减信息计算链路连通时间,然后再构建链路稳定函数,随后通过稳定函数设置定时器,从而选择最优的节点作为下一跳转发节点。实验数据仿真表明,提出的LET-RP路由有效地提高了吞吐量,降低了端到端传输时延。Mobile Ad Hoc Networks is the wireless networks consisted of a couple of mobile nodes.Mobility of nodes and Wireless transmission environment are a challenge for transmitting data.Therefore,Link Expiration Time-based routing protocol in Mobile Ad Hoc Networks(LET-RP)is proposed in this paper.In LET-RP,the Link Expiration time is estimated by mobile information and path fading statistis,and the link stable function is constructed.Finally,we use a timer function,and select the best relay.Simulation results show that the proposed LET-RP improve throughput,and reduce delay.
