摘　　要：针对移动自组网中节点高速运动、网络拓扑变化剧烈导致的网络性能下降问题,在无线自组网按需平面距离向量(Ad hoc On-demand Distance Vector,AODV)协议基础上,提出一种基于模糊逻辑具有链路稳定感知意识的移动自组网路由协议(Fuzzy Stable AODV,FS-AODV)。选择链路维持时间和邻居节点变化度作为链路稳定程度的考量指标,从模糊逻辑的理论出发,将两个链路稳定指标融合为评价该链路稳定性的综合稳定值,并作为最终的稳定路径决策依据。仿真结果表明,该方法在动态环境中的网络性能优于AODV,对节点高速运动引起的拓扑变化有很好的适应性,也验证了基于经验设计的用于融合链路稳定指标的模糊规则的合理性。Aiming at the problem of network performance degradation caused by the high-speed movement of nodes and the drastic changes in network topology in Mobile Ad hoc Network,a fuzzy logic-based linkstability-aware routing algorithm,Fuzzy Stable AODV(FS-AODV)is proposed on the basis of the Ad hoc On-demand Distance Vector(AODV)protocol.The life of link and the change degree of neighbour nodes are selected as the consideration indexes for link stability,from the fuzzy theory,two indexes above are fused into a comprehensive stability metrics for evaluating the stability of link and used as the final basis for stable path decision.Simulation results show that the algorithm outperforms AODV in dynamic environments,is well adapted to topological changes caused by high speed movements of nodes.The rationality of fuzzy rules based on experience designed for fusing link stability metrics is also verified.
