摘　　要：分析了无线传感器网络在核电站突发核事故时核辐射监测中的路由需求,针对经典的分簇路由协议LEACH选举簇头仅单一考虑节点位置或能量分布而产生冗余节点的问题,提出了模糊分簇路由协议,对簇头广播信号与数据传输的过程进行优化,降低了传感节点的冗余度。运用Matlab平台对改进前后的协议进行仿真,对节点的存活率与整个网络的总能耗进行分析对比,仿真结果表明,改进后的协议能有效减少网络的总能耗,延长了网络的生命周期。The routing demanding of wireless sensor network in nuclear radiation monitoring is analyzed when nuclear power station accident happens. Aiming at the problem that the classical LEACH cluster heads election only consider senor＇s location and energy to produce a lot of redundancy nodes. We puts forward the fuzzy cluste-ring routing protocol and optimizes the cluster broadcasting signals and transmitting data and reduce the redundancy of the sensor nodes. The simulation experiment is carried out in matlab platform . The survival rate and the total energy consumption of the network are analyzed. The simulation results show that the improved protocol can effectively reduce the network of total energy consumption and prolong the network life cycle.
