摘要
针对LEACH协议在民航桥载设备无线传感器监控网络应用中暴露出数据吞吐量小、节点能耗高及网络生命周期短的问题,提出对无线监控网络所采用LEACH协议的簇头选举和成簇机制进行改进,改进算法主要把节点当前能量和节点到基站的距离作为簇头选举阈值公式的参考因子,以及在成簇阶段引进基于路径权重值的成簇机制,使形成的簇更有利于整个监控网络性能的提升。最后利用Matlab软件对桥载设备监控网络建模仿真,结果表明,改进算法在桥载设备监控网络的数据吞吐量、生命周期以及能耗方面较原系统路由协议均具有优越性。
For the problem of low data throughput,high energy consumption of nodes and short network life cycle,ex- posing during the applications of civil aviation bridge load equipment monitoring wireless sensor network（BLEMwsn） for LEACH ,proposed for the improvement of cluster head election mechanism and clustering mechanism.Improved al- gorithms which are more conducive to enhance the overall monitoring network performance mainly attach importance to the reference factor including current energy of nodes and distance from current node to the base station and also introduce the clustering mechanism based on angle and the energy consumption of distance. Finally,by Matlab simu- lation modeling software,the simulation results show that improved algorithms have advantages in aspects of data throughput,life cycle and energy consumption against the original routing protocol of BLEMwsn.
