摘　　要：提出一种面向移动自组织网络应用的中继节点选择策略。依据生存时间、有效带宽和队列容量3个度量自适应计算每一个节点的转发意愿度量;依据节点之间的链路传递概率、转发频率和握手损耗3个度量计算节点的转发能力度量;将节点的转发意愿度量和转发能力度量进行加权融合,用于度量无向图模型中节点之间的边的长度属性;依据边长最大准则,选择最优的中继节点进行数据转发。仿真结果表明,与EM-AODV和TARF两种常用的路由协议相比,采用该策略建立的路由具有更高的报文送达率和更低的端到端传输延时。A relay node selection strategy for mobile ad hoc networks application was presented.Forward willing metric of each node was calculated according to its three metrics including lift time,available bandwidth and queue capacity.Forward ability metric between two nodes was calculated according to three metrics including link delivery probability,forward frequency and hand loss.Forward willing metric and forward ability metric of each node were fused,to describe the length property of the edges between two nodes in the undirected graphical model.The optimal relay nodes for data forwarding were selected based on the criterion of maximum edge length.Simulation results show that,compared with two common routing protocols including EM-AODV and TARF,the route built using the proposed strategy has higher packet delivery rate and lower end-to-end transmission delay.
