Analysis of LEACH Protocol Based on Ant Algorithm

Abstract

According to high energy losing caused by directly communication between cluster heads and Sink node in LEACH algorithm, a new algorithm based on ant algorithm is formally deriver in this paper. The algorithm takes advantage of the features of ant algorithm, i.e. being easy to be realized, and supporting multi-path to build cluster routing, through the information of its distance and remaining energy of nodes. Then the distance and remaining energy of the neighborhood were integrated in the computation of pheromone concentration. The results of simulation show that compared with LEACH, the algorithm can get a better balance of the energy dissipation and prolong the network lifetime.

Optimal LEACH Protocol with Improved Bat Algorithm in Wireless Sensor Networks

“…However, the LEACH protocol does not consider current node energy, and the selection of random cluster-heads can easily result in uneven energy consumption among network nodes, which shortens the network life cycle. A monitoring blind spot can then form in the rear stage of the network and affect overall network performance [11,12].…”

A Low Energy Uneven Cluster Protocol Design for Wireless Sensor Network

“…There are also some works for the improved Leach protocols [6][7][8][9], The literature [6] proposed a steady group clustering hierarchy algorism, it firstly divide the network into groups, and then directly change the group into the cluster. But it does not consider the multi-hop between the cluster heads.…”
