能量非均衡节点在无线传感网络立体空间的LEACH路由研究

摘要

For three-dimensional space where distributed nodes with uneven initial energy, whole network' s mathematic model was build based on MATLAB, radio energy dissipation model was introduced, and fittest counts of cluster for network was presented. Through analyzing characteristic of network and LEACH protocol, LEACH protocol was improved for this network. The results of simulation in MATLAB indicated that improving LEACH protocol could improve energy distribution between nodes, and the stable cycle of network was prolonged.%针对无线传感器网络中节点初始能量不均匀且工作在立体空间中的网络分布问题,建立了整个无线网络数学模型,介绍了该数学模型中节点与节点间的能量扩散模式,并针对该模型研究网络中节点数据传输的能量消耗形式,给出了基于节点能量消耗模型网络中要选举的最佳簇头个数.通过分析LEACH算法和网络特性,提出了对LEACH算法的改进算法,并利用MATLAB对改进算法进行了仿真.结果表明,改进算法使网络所消耗的能量在节点间分布更加均匀,延长了网络的稳定周期.
