摘　　要：针对三维空间下无线传感器网络路由节能问题,该文对低功耗自适应分簇(LEACH)路由算法的簇首选择机制进行优化。将传感器节点的剩余能量、网络的平均能量以及节点距离基站的位置作为阈值公式的参考因子,在协议簇建立阶段给出簇首个数最优值计算公式和簇首选举阈值公式。仿真结果表明,该算法在相同运行条件下节能效果良好,具有更多的剩余总能量及较长的生存时间,能够有效均衡网络的能量,延长网络生命周期。Aiming at the energy-saving problem of the wireless sensor networks routing protocol in three-dimensional space, the selection mechanism of cluster heads of the low-energy adaptive clustering hierarchy （LEACH）routing is optimized, and a energy-efficient routing protocols based on the remaining energy of sensor nodes, the average energy of networks and the distance from sink to node is designed. A new cluster selection mechanism based on the optimal cluster heads and the energy adapt threshold are presented, and their cluster head selection mechanism design is optimized. The simulation results show that the algorithm has more rest total energy and longer survival time in the same condition, and can make the network achieve the better energy-saving effect and prolong the life cycle of the network.
