摘　　要：该文提出了一种新的移动Ad hoc 网络QoS 路由算法:模糊逻辑QoS 动态源路由算法。算法从模糊理论的思想出发,将业务的多个QoS 参数进行综合评判产生一类以语言变量描述的请求,在修改动态源路由协议为多径路由算法的基础之上,对比各条路径综合模糊路由状态,选择出最适合业务请求的路径。仿真显示算法在支持QoS 的同时对移动Ad hoc 网络因拓扑动态变化而引起的信息不精确性有很好的适应度。A new QoS routing algorithm for mobile Ad hoc networks, Fuzzy Logic QoS Dynamic Source Routing （FLQDSR）, is proposed in this paper. The idea of FLQDSR starts from the fuzzy theory. It integrates the multiple QoS parameters of traffic into one request that is represented by Language variable through integrated fuzzy judgment. Based on the multiple paths routing algorithm which is modified the Dynamic Source Routing （DSR）, FLQDSR compares the integrated QoS fuzzy value of each path and selects the most appropriate one according to the fuzzy rules. Simulation results show that FLQDSR can tolerate the imprecise information which is caused by the dynamic network topology well while supporting QoS function.
