Sectored LEACH (S-LEACH): An enhanced LEACH for wireless sensor network

Abstract

Due to the importance and the need of wireless sensor networks in several applications, lots of research has been carried out. The utmost challenging issue is regarding the energy depletion of the network such that reducing the consumed energy leads to extending the network lifetime. The most popular routing algorithm for that purpose is LEACH. Regrettably, it has some limitations, and this work produces Sectored-LEACH, which proposes solutions for these limitations. The main idea is about splitting the communication area into sectors to decrease the transmission distance, hence reducing the overall consumed energy. Results show a decrease in the total consumed energy, an increment in the network lifetime compared with the original LEACH and other four algorithms Q-LEACH, I-LEACH, RCH-LEACH and ME-LEACH. S-LEACH has the best results regarding the comparison of performance metrics parameters.
