Jun Tao · Computer Technology and Development · 2009
Reducing node energy consumption to extend network lifetime is a vital requirement in wireless sensor network.In this paper,an improved GAF algorithm with hexagon-based virtual infrastructure is proposed.The goal of this algorithm is to lengthen the side of the grid,to enlarge the area of grid and to use the nodes in the overlap areas as transfer nodes among the cluster heads.This algorithm is analyzed and validated for performance through computation and simulation,the result of which suggests it can reduce the average power consumption and lengthen the network lifetime efficiently.
