摘　　要：针对目前无线传感器网络节点覆盖优化方案中,无线传感器网络节点位置移动会破坏节点间的共享密钥的问题,采用了一种基于泰森多边形形心引力和存在共享密钥节点间的安全连接虚拟力的无线传感器网络部署方案。该方案以提高节点覆盖率为优化目标,引入安全连接虚拟力,以保证节点的安全连接;采用改进泰森多边形形心引力的虚拟力方案,能够有效指导节点散布过程和实现全局优化。通过仿真实验表明,本文方案能够提高节点的覆盖率,并且能够的减小存在共享密钥的安全连接的破坏。An uneven clustering routing protocol named UCRP of wireless sensor networks is proposed according to the long-narrow geographical characteristics of deep roadway. Long-narrow WSNs is treated as linear network which is well planned. If the area is closer to Sink node,the smaller its campaign radius making is,which can preserve some energy for inter-cluster data forwarding. An new weight formula is constructed to elect the candidate cluster heads which determine cluster heads by certain campaign radius. Data forwarding is accomplished by single-hop within the cluster and multi-hop between the cluster heads. Simulation results show that UCRP can solve the hot-spot problem caused by uneven load energy in linear network,and prolong the entire network life.
