| 摘 要： | 提出多跳无线网络中反馈式机会路由(FOR).给出基于EPDTX指标的转发候选集产生策略,有效地做到了减少网络重发包数和传输时间消耗的平衡.根据候选集中节点ACK返回情况,分析网络局部拥塞状况,动态调整转发候选集和转发优先级,并给出基于ACK反馈的启发式候选集产生算法.仿真试验表明,FOR比传统路由算法(AODV)和极端机会路由算法(ExOR)多跳传输性能上有明显提升,并具有较强的抗网络拥塞能力.

| Abstract: | This paper describes Feedback Opportunistic Routing (FOR) in multihop wireless networks. Firstly,a strategy for selecting Forwarding Candidates Set based on metric named Expect Per-Decrease Transmission Count (EPDTX) is proposed. It can balance the decrease transmission count and time cost. Secondly,on the condition of ACK returned by Candidates,this paper analyses local network congestion,dynamic updates Forwarding Candidates Set and Relay Priorities,and also provides the Heuristic candidate selection algo... |
