摘　　要：针对无线传感器网络存在能耗和投递率等约束问题,提出了一种利用能效优化的自组织位置感知协议(EESLP)。首先,根据主干锚节点的位置感知将网络构建成树结构;然后,利用拓扑控制优化网络的拓扑结构来维持网络的连通性和覆盖范围;接着,在路径选择过程中加入节能机制,均衡网络负载;最后,利用自组织方式最小化消息传输和接收次数,降低消息复杂度,减少协议开销。仿真实验结果表明,该协议具有良好的能量效率,相比其他几种能量感知协议,该协议具有更高的包投递率和更低的能耗,有效延长了网络寿命。In order to solve the energy consumption and delivery ratio constraint problem in wireless sensor network, an energy efficient self-organized location aware protocol is proposed. Firstly, according to the location aware of backbone anchor nodes con- struction network into a tree structure; secondly, using topology control optimize the network topology to maintain network connectivi- ty and coverage; then, adding energy saving mechanism in the path selection process, balance the network load; using self-orga- nizing minimize the number of message transmit and receive to reduce the message complexity and protocol overhead. Simulation re- suits show that, the protocol has good energy efficiency, and it has higher packet delivery ratio and lower energy consumption, which indicates that it has effectively prolonged the network lifetime.
