摘　　要：无线传感器网络中,簇头选举不合理将导致节点能量消耗过快,使其过早失效,网络过早结束生命周期。对此提出一种节点信息感知的非均匀分簇路由算法:充分考虑节点邻域基数、位置感知、剩余能量,通过非均匀分簇确定最优簇头;簇的形成阶段,节点加入距自己最近的簇,通信上采用簇内单跳、簇间单跳、多跳相结合的方式。仿真实验表明,该算法与LEACH,CEBRCA相比,在网络生命周期、能量利用率和数据发送方面都具有较好的性能。In Wireless Sensor Networks（WSN）, cluster head election unreasonable will lead nodes consuming their energy quickly, the network end their life early. In this paper a sensor information aware uneven clustering routing algorithm （SIAUCR） is proposed where cluster heads are selected based on node＇s neighborhood cardinality, the distance from node to base station and the node＇s residual energy. In cluster formation stage~ the node join the nearest cluster, trans- mission through single hop in the cluster single hop and multi-hop between cluster heads. Simulation results show that the SIAUCR algorithm is more effective in extending the network life, energy savings and transmission than LEACH, CEBRCA.
