WEP: An Energy Efficient Protocol for Cluster Based Heterogeneous Wireless Sensor Network

TL;DR

This paper introduces WEP, an energy-efficient routing protocol for heterogeneous wireless sensor networks that improves stability period and network lifetime by combining clustering and chain routing strategies.

Contribution

The paper proposes a novel weighted election protocol (WEP) that enhances energy efficiency and stability in heterogeneous WSNs through a combined clustering and chain routing approach.

Findings

WEP outperforms LEACH, SEP, and HEARP in stability period and network lifetime.

Higher extra energy in heterogeneous settings extends stability period.

Simulation results validate the effectiveness of WEP.

Abstract

We develop an energy-efficient routing protocol in order to enhance the stability period of wireless sensor networks. This protocol is called weighted election protocol (WEP). It introduces a scheme to combine clustering strategy with chain routing algorithm for satisfy both energy and stable period constrains under heterogeneous environment in WSNs. Simulation results show that new one performs better than LEACH, SEP and HEARP in terms of stability period and network lifetime. It is also found that longer stability period strongly depend on higher values of extra energy during its heterogeneous settings.
