摘　　要：为了降低无线传感器网络(WSN)路由节点的能量损耗,提高网络的寿命周期,需要进行路由节点的优化分布设计。传统方法采用CSMA/CA有限竞争的信道分配模型进行WSN的路由探测算法设计,实现能量均衡,在节点规模较大和干扰较强时,节能的能耗开销较大。提出一种基于能耗量化传导的WSN路由探测算法,首先建立WSN的分簇能耗调度模型,以能量控制开销、丢包率、传输时延等为约束参量指标进行路由探测的控制目标函数的构建,然后采用路由冲突协调机制进行能耗量化分配,结合WSN传输信道的能量传导均衡模型实现WSN路由的优化探测和WSN节点的优化部署。仿真结果表明,采用该方法进行WSN路由探测设计时网络的能效较高,传输时延和误码率等参量指标的表现优于传统方法。In order to reduce the energy loss of routing nodes in wireless sensor networks（WSN）and improve the lifetime of the network,it is necessary to design the optimal distribution of routing nodes.Traditional methods use channel allocation model based on CSMA/CA limited competition for WSN routing detection to achieve energy balance,but with the expansion of the network nodes and interference enhancement,saving energy consumption costs more.A WSN routing detection algorithm based on energy quantitative conduction was proposed in this paper.Firstly,the cluster energy consumption scheduling model of WSN is established and the routing detection control objective function is constructed when taking the energy control overhead,packet loss rate and transmission delay as the constraint parameters.Then the coordination mechanism of routing conflict is used to realize the quantitative distribution of energy consumption,and the optimization of WSN routing detection and WSN node deployment is achieved by the energy equilibrium model of WSN transmission channel.Simulation results show that the proposed method is superior to the traditional methods in WSN routing detection design due to its higher energy efficiency of network,lower transmission delay and bit error rate.
