摘　　要："热区"问题是影响WSN网络性能的关键问题。为了解决此类问题,提出了一种基于能耗优化的WSN非均匀分簇路由算法。在簇头竞争阶段,构造不均匀的竞选半径,每个节点根据邻居节点表中的信息,依据自身能量、距离平均值等,计算其簇首等待时间,最终选举出簇首。在簇间多跳路由选择阶段,利用簇头剩余能量、距离、簇内剩余能量均值等影响因子选择中继节点,构建数据传输路由树,进而进行数据转发。计算机仿真结果表明,该算法能有效节省网络能量和平衡能耗,延长生命周期。＂Hot Zone＂ is one of the key problems in wireless sensor networks（WSN）. In order to solve this problem a modified algorithm based on energy optimization for uneven clustering routing is proposed. During the stage of clustering completion, the uneven competition radius of nodes is formed, and each node, in accordance with the information in adjacent nodes table, its own energy and the average distance, calculates the waiting time of cluster-head, and ultimately elects the cluster head. By using residual energy, average distance of the cluster head, and intra-cluster residual energy to select a relay node, the data-transfer routing tree is constructed. The computer simulation indicates that the routing protocol can efficiently reduce and balance the energy consumption, prolong the life-cycle of wireless sensor network, and improve the link quality.
