摘要
传统的LEACH协议采用分布式算法,未考虑节点能量,改进的LEACH-C采用集中式的选簇算法,对于大规模的网络不适合。针对这些问题,提出一种基于位置和剩余能量的局部集中式分簇算法LEACH-LC。由簇头对簇成员的能量、位置进行评估,采用模拟退火算法确定局部较优的分簇。OMNet++仿真结果表明,改进算法在网络生存期和节点能耗上优于LEACH算法。
The traditional LEACH routing protocol adopts a distributed algorithm,and does not take node energy into consideration.The improved LEACH-C algorithm is a centralized algorithm which does not meet for large networks.To solve these problems,a local centralized cluster head selection algorithm LEACH-LC is proposed.Cluster head evaluates the energy,location of the members,and then determines the local optimum clusters.The OMNet ＋ ＋simulation results show that improved algorithm extends network lifetime and reduces energy consumption of nodes in comparison with LEACH.
