Abstract
Energy efficient routing protocols are an active research area in Wireless Sensor Networks (WSNs). Like prior research works in efficient-efficient routing protocols, we enhance the LEACH cluster-head (CH) threshold mechanism. Our approach mainly focuses on the idea of maximizing the network lifetime on the basis of CH nodes remaining energy levels. In LEACH, CH changes occur during every round of the network irrespective of their energy levels. In this scenario, we propose an energy threshold function as well as an optimal CH threshold function to specify the dynamicity of the CH, whether to change the cluster-topology often or not with the consideration of its current energy levels. In this regard, simulation results show that the proposed mechanism can maximize the network lifetime effectively and delivers three times more data messages while comparing with the other known energy-efficient protocols from the literature.
Highlights
The advantages of Wireless Sensor Networks (WSNs) bring many potential applications, such as industrial control systems, vehicle tracking, home and office automation, water supplies, surveillance, wildfire monitoring, pollution monitoring, weather forecasting and enumeration are considered in the environmental monitoring applications [1,2,3].In sensor networks, clustering protocols have the higher network performances in terms of network lifetime, less transmissions and low latencies than the traditional communication methods
This paper presents a Single-hop Cluster-Based and Energy Efficient Protocol (SCEEP) Wireless Sensor Networks for prolonging the network lifetime based on Cluster-Heads remaining energy and optimal CH range levels
For avoiding the communication overheads and maximizing the network lifetime, we propose the second principle of clustering threshold function, which has been designed based on CHs remaining energy and fixed optimal cluster-head ranges at every round
