摘要 无线传感器网络(WSN)具有的能量有限。其能量利用效率的高低直接影响着网络的生命周期。为了提高无线传感器网络的能量利用效率,提出了一种能量感知非均匀成簇路由优化算法(Energy Awareness Unequal Clustering Routing Optimization Algorithm,EUCR)。该算法通过节点在网络中所处的位置确定各节点的邻居节点,并以局部能量选举簇头,各簇头根据其邻居节点构建非均匀分簇网络。同时该算法在路由阶段考虑了簇头的剩余能量和转发代价。仿真结果表明,EUCR算法能有效提高网络的能量利用效率,并延长网络的生命周期。 Wireless sensor networks （ WSN ） have limited energy, so its energy efficiency directly affects the life cycle of the net- work. In this paper, a new kind of energy awareness unequal clustering routing optimization algorithm （EUCR） is put forward. EUCR algorithm selects duster head by local energy, and it expressly makes an optimization in clustering method and route. The simulation results show that EUCR can effectively improve the network energy efficiency, and prolong the life cycle of the network.
