B-LEACH: A Clustering Protocol for Wireless Sensor Networks based on Bacterial Foraging Algorithm

Abstract

Wireless sensor networks [WSN] are popular as they are potentially low cost solution to various real world challenges. Environment is monitored by the autonomous nodes of the WSNs. Recent research in WSN has led to various new routing protocols. Routing protocols have proven to increase the network throughput, reduced delay in packet transfer and save energy. Hence in this work we propose a novel clustering protocol that uses bacterial foraging algorithm [BFOA] inspired approach towards improving the existing basic LEACH protocol for reduction in energy consumption with respect to communication, aiming to enhance the network lifetime. Simulated results prove that implementing this kind of computational intelligence in the pre-existing protocol considerably improves its performance. Keywords:
