Abstract

Background/Objectives: Wireless Sensor Networks (WSNs) are proving themselves as vital part of technology advancements. A WSN comprises of multiple sensor nodes and a base station as a sink node (i.e., for data communication). We propose a modified algorithm to improve the performance and life time. Methods/Statistical Analysis: Sensor nodes are battery powered and placed over remote locations to analyze data. Therefore, the usage of battery affects the whole network lifetime. Communication methods between nodes and base station are based on various protocols. Among all protocols, clustering protocols are considered the best protocol so far (lifetime and throughput performance). Lifetime and throughput are crucial parameters of a network. Findings: In this paper, the critical parameters of a WSN protocol Low Energy Adaptive Clustering Hierarchal (LEACH) are improved using the proposed algorithm. Simulation results of the proposed scheme for the network lifetime and throughput are compared with original LEACH protocol. We achieve better performance as compared to the conventional technique with less computational complexity and better lifetime. Application/Improvements: Further improvement can be achieved if use some hybrid algorithm.
