Hybrid Hierarchical Clustering Protocol in Wireless Sensor Networks based on Ant Colony Algorithm and MR-LEACH

Energy consumption is one of the most important factors in wireless sensors networks (WSN). In fact, many protocols have been modified to enhance the lifetime of deployed sensors in a wireless network. In our work, we are investigating new optimization methods such as Ant Colony, where we aim to enhance the lifetime of the network based on a better network clustering. For experimental purposes, we implemented three protocols LEACH, MR-LEACH and our proposed ant colony algorithm. We have used the MATLAB environment in order to compare these protocols vis-à-vis the energy consumption and the lifetime of the network. Our proposed protocol showed better results in terms of throughput and life time compared to the original LEACH and MR-LEACH protocols.
