摘　　要：针对无线传感器网络中的"热区"问题,提出了一种新的低能耗的非均匀分簇路由协议——LEUC。该协议中,采用分布式与集中式相结合的方式依据节点的剩余能量与相对圆环中心线的位置选择簇首,成簇时综合考虑簇首能量与信号强度,簇内根据簇的大小采用单跳或者多跳传输数据,簇间构建多跳动态路由。仿真结果表明:LEUC协议可以较好地解决"热区"问题,均衡减少节点能耗,延长网络的生存周期。Aiming at the ＂hot spot＂ problem in wireless sensor networks,the paper proposes a new low energy and uneven cluster-based routing protocol.In the protocol,it combines distributed and centralized method according to the last energy of node and the relative to circle centerline to select cluster head,in accordance with the last energy of cluster head and the signal power to form cluster;and according to the size of cluster to use one-hop or multi-hop to transmit data,form the multi-hop dynamic routing among cluster heads.Simulation results show that： LEUC protocol can solve the ＂hot spot＂ problem,balance and reduce the energy consumption of nodes and prolong network lifetime.
