摘　　要：针对能量不足可能引起的组播路由不稳定问题,提出了一种基于模糊逻辑的组播路由协议。该协议首先建立组播网格,然后采用模糊逻辑选择组播路由。在组播路由选择阶段,将节点的能量和距离两个参量作为路由评估的依据,借助模糊逻辑建立节点能量和距离与路由质量之间的模糊联系,采用高斯隶属度函数实现输入参量的模糊化处理,采用质心法进行输出参量的去模糊化处理,依据输出参量选择最优组播路由。仿真结果表明,与现有组播路由协议相比,该协议的报文送达率更高,端到端平均延时更小。In order to solve the unstable routing problem of multicast routing caused by insufficient energy,a multicast routing protocol based on fuzzy logic is proposed.This protocol firstly establishes a multicast mesh and then uses fuzzy logic to select the multicast routes.In the multicast routing selection stage,two parameters of energy and distance of the nodes are used as the basis for route evaluation.Fuzzy logic is used to establish the fuzzy relation between energy and distance of nodes and route quality.The Gaussian membership function is used to execute fuzzification of input parameters.The centroid method is used to execute defuzzification of output parameter,which is used for select best multicast routes.The simulation results show that,compared with the existing multicast routing protocols,this protocol has higher packet delivery rate and lower end-to-end average delay.
