摘　　要：提出一种安全高效的路由协议,包括路由表创建、信任度计算和看门狗监测3个模块。各节点的看门狗监测组件定时监测其下一跳节点的数据包转发行为,结合链路送达概率估算下一跳节点的期望转发频率下限;在此基础上,信任度计算模块结合Beta分布估算邻居节点转发行为正常比例的期望值,作为邻居节点的信任度;路由表创建模块结合信任度和链路送达概率制定可靠性度量准则,融合距离进展度量选择最优的下一跳候选节点。仿真结果表明,与EN-AODV和ARAN路由协议相比,该路由协议的报文送达率高、端到端平均延时低。A safe and efficient routing protocol was proposed, including three modules named as routing table creation, credibili-ty calculation and watchdog monitoring. The watchdog monitoring components of all nodes regularly monitored the packet for-warding behavior of its next-hop node, and estimated the low bound of expected forwarding frequency of the next-hop node by combining the link delivery probability. On this basis, credibility calculation module estimated the proportion of the normal for-warding behavior of the neighbor nodes using Beta distribution. The routing table creation module designed the reliability metric by combining credibility and link delivery probability, and selected the optimal next-hop candidate nodes by fusing reliability metric and progress metric. The simulation results show that, compared with the EN-AODV and ARAN routing protocol, the proposed routing protocol has higher packet delivery rate and lower average end-to-end delay.
