摘　　要：针对无线传感器网络中能量消耗不均引起的热区问题,提出一种基于移动sink节点的WSN节能路由协议MSERP,将整个网络分成若干个虚拟网格,根据节点剩余能量和到网格重心距离选举簇头。通过PSO算法来确定sink的下一个移动位置,粒子适应值函数由簇头到sink节点的距离和sink节点周围簇头能量因素定义。仿真结果表明,该协议有效地解决了热区问题,提高了网络的生存周期。WSN energy-efficient routing protocol based on a mobile sink node of（ MSERP） was proposed in this paper. The whole network was divided into some virtual unit, which choose cluster heads according to the residual energy and the distance of a node and a virtual unit of center. The next stay the best location of the sink is determined by PSO algorithm. The definition of the fitness function of particle is based on two factors ： the distance of cluster heads to sink and the energy of cluster heads around the sink. Simulation results demonstrate that the protocol can efficiently solve the hot spot problem and prolong the network lifetime.
