基于多尺寸网格的LEACH协议改进
Improvement of LEACH Protocol Based on Grids with Multiple Dimensions
摘要
Abstract
A new energy efficient routing protocol of MDG-LEACH is proposed in the paper,which is based on the question of numerous redundancies with data collecting in nodes and imbalance of energy consumption in Low Energy Adaptive Clustering Hierarchy ( LEACH ) protocol. It selects active nodes based on virtual grids and multiple dimensions grids. Further, it adopts cluster head choice mechanism in overall consideration of residual energy and spatial distribution of nodes and establishes the shortest transmission route tree between cluster heads and base station by the dynamic programming method for date transmission. Simulation results show that MDG-LEACH protocol improves LEACH protocol and the improved LEACH protocol ( Computer Technology and Development, 2013, No. 2 ) in balancing energy consumption of nodes and prolonging the life time of wireless sensor network effectively.关键词
