Improvement of LEACH Based on Wireless Communication Model and Ant Colony Algorithm

Abstract:

Cluster structure is irrational and communication between cluster-head and sink node is single-hop in LEACH (Low-Energy Adaptive Clustering Hierarchy) for wireless sensor network. An improved algorithm based on wireless communication model and ant colony algorithm is proposed to solve these problems. In this paper a formula of clustering cost is proposed on the basis of wireless communication. At the same time, the ant colony algorithm and LEACH are combined to build pheromone in the entire network according to the distance between the neighboring cluster heads and their remaining energy in order to form multi-hop routing between them. Finally, the results of simulation show that the improved algorithm can balance energy consumption of nodes and prolong the lifetime of the whole network.
