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。
A QoS multicast routing algorithm based on decision factor (QCFRA_W, A QoS Multicast Routing Algorithm Based Choice Factor in (QCFRA_W)) is proposed to solve the QoS constraints of wireless sensor networks, such as remaining energy, delay, delay jittering and bandwidth. WSN) algorithm. The QCFRA_W algorithm makes use of decision factors to make reasonable use of the resources of neighbor nodes, which can achieve higher success rate of routing with smaller routing message overhead, adjust link weight according to different proportion of link quality parameters, and according to the dynamic information We get the weight of each link and select the routing mechanism, and analyze the complexity of the algorithm. Simulation results show that the QCFRA_W algorithm has better characteristics in routing success rate, multicast tree cost and energy consumption.
