The Algorithm of Threshold Model Based on LEACH
-
Abstract
An improved scheme is proposed under the consideration of the defect of LEACH in this paper.This proposal determines whether the cluster head has been changed by means multiple conditions instead of the original LEANCH protocol which takes the unit of 'round' as the cluster head.In that way, the energy could use for data transmission that is can increase the total amount data which sink node receives.Simulation results show that this algorithm possesses higher energy usage and longer survival time than those of LEACH.
