基于LEACH协议节能路由算法的研究与优化

RESEARCH AND OPTIMISATION OF ENERGY-SAVING ROUTING ALGORITHM BASED ON LEACH

针对LEACH(Low-Energy Adaptive Clustering Hierarchy)协议在分簇算法中存在的未考虑节点的剩余能量,簇头节点分布位置不合理等缺陷,提出基于LEACH协议的节能路由改进算法。在原有协议的基础上,优化了成簇的条件,充分考虑了剩余能量与相对位置,使得无线传感器网络的寿命得到进一步延长。仿真实验结果表明改进后的算法有效降低了网络能耗,提高了无线传感器网络的性能。

LEACH protocol has many drawbacks in clustering algorithm, such as the remaining energy of the cluster is not considered and the location of the cluster head is unreasonably distributed. In light of this, we propose a LEACH-based improved energy-saving clustering routing algorithm. On the basis of previous protocol, it optimises the condition of clustering, and fully considers the residual energy and the relative location of cluster nodes, enables the network life of WSN to be further extended. Results of the simulation experiment also show that the improved algorithm effectively reduces the energy consumption, and improves the performance of the WSN as well.
