摘　　要：针对无线传感器网络中传感器节点通信能力和能量有限的特点,提出一种新的无线传感器非均匀分簇的路由协议NUCRP(new unequal clustering routing protocol).该协议的核心是:簇头采用竞选方式,首轮所有节点参与竞选,将节点的剩余能量、相邻节点的个数以及节点到基站的距离作为评价标准,以保证簇内最优的节点成为簇头.节点路径搜索运行蚁群算法,以寻找从簇头到基站最优的多跳路由.后续轮次不再每轮重新成簇,只有当簇头剩余能量小于预测能量时才重新成簇和路由更新,从而达到自适应、动态优化地建立和维护路由.仿真结果表明,该路由协议能有效节约能量和均衡节点能耗,从而延长网络的生命周期.For wireless sensor network node communication ability, energy is limited, a new unequal clustering routing protocol （NU- CRP ） is proposed for wireless sensor network. The protocol lets all the nodes take part in cluster head competition, take residual ener- gy,the number of neighbor node and distance between node and sink as evaluation criteria to ensure the optimal node winning. The cluster head nodes run ant colony algorithm to search the optimal multi-hop routing from cluster heads to sink node. The Subsequent rounds not longer cluster each round, Only when the residual energy of cluster head is less than predicted energy to cluster and update routing, the protocol enables its routing establishment and maintenance more self-adaptive and dynamic. The simulation shows that the routing protocol can efficiently reduce and balance the energy consumption, and prolong the wireless sensor network survival period.
