Simulation Analysis and Improvement of LEACH Protocl

Based on in-depth analysis of the design goal of routing protocol for the wireless sensor network,and for the cluster head of low Energy Adaptive Clustering Hierarchy protocol would both fuse the data sent by cluster nodes and transfer the processed data to the base-station,thus the energy consumption becomes fairly large.Therefore the idea of load balance and formed chain of cluster nodes is introduced to improve LEACH,while the greedy algorithm is used to make the data transmission in chains,and the work time of the cluster head is extended as much as as possible.This could improve the stable phase of the cluster and realize load balance of the whole network nodes.The simulation with NS2 network simulation tool shows that the network life-time with this modified LEACH protocol could be greatly extended.
