改进的基于NS2仿真的无线传感网LEACH协议

摘要

This paper proposes an improved LEACH protocol method based on analysing the LEACH protocol of WSN in operating mechanism, adapting to the scene and exiting defects. At last, the emphases is proving the improved LEACH protocal method’s practical operating performance by simulating with NS2 environment. The simulation results show that the improved LEACH protocol method can extend the operating life of WSN, save the limited energy of nodes, reduce the mass extinction of nodes and keep an adequate quantity nodes to operate compared to the routine LEACH protocol.%分析了WSN中LEACH协议的运行机制、适应场景以及存在缺陷的基础上，提出了调整改进LEACH协议的方法，最后，基于NS2环境对改进后的协议进行仿真验证，并重点验证改进后协议的实际运作性能。通过仿真验证可知，和常规LEACH协议相比，改进后的LEACH协议可以延长WSN的运行寿命、节约节点中有限的能量、阻止节点大量消亡、保持运行节点的数量。
