摘　　要：针对无线传感器网络特点和节点的剩余能量、延时、延时抖动、带宽等QoS约束问题,提出一种基于抉择因子的QoS多播路由算法—QCFRA_W(QCFRA_W,A QoS Multicast Routing Algorithm Based Choice Factor in WSN).算法。QCFRA_W算法使用抉择因子合理利用邻居节点资源,能够以较小的路由消息开销取得较高的路由成功率,依据链路质量参数的不同比重进行调节链路权重,并依据从其链路的动态信息中得到各条链路的权重选择建立路由选择机制.并对算法进行了复杂性分析。仿真实验表明:QCFRA_W算法在路由成功率、多播树费用、能量消耗方面均具有较好特性。In allusion to the network characteristics of wireless sensor network and the strict energy limitationin wireless sensor network,discussing the QoS constrained multicast route problem in the wireless sensor network., mainly including QoS constraints, such as, remainingenergy of nodes, time lapse , time lapse wobble ,bandwidth and so on.this paper designs a multicast routing network model applied to wireless sensor network with QoS constraints, and presents a QoS multicast routing algorithm based on Choice Factor by inducting the choice factor mechanism and the choice competition mechanism (QCFRA, A QoS Multicast Routing Algorithm Based Choice Foctor in WSN).the algorithmic realization process and the step is given, and carry through the certification of algorithmic validity and the analysis of complexity.The experiment indicated that the algorithm has fairly good characteristic in terms of the route success rate,the cost of multicast tree.and Energy consumption
