A Sector-Based Energy-Efficient Lightweight Clustering Algorithm

Abstract

Wireless sensor networks consist of a large number of nodes with constrained energy supply. Energy efficiency is hot and challenging issue in wireless sensor networks. Existing studies have shown that clustering is one of the efficient techniques to improve energy efficiency. An easy-to-implement and flexible method for even clustering and cluster head selection is beneficial to optimize network stability and energy efficiency. In this study, a sector-based lightweight and flexible clustering algorithm is developed to reduce node energy dissipation and optimize energy efficiency. Our proposal divides the area into virtual sectors. In the meanwhile, an even sector cluster is created using the sector decomposition approach. Based on the total communication distance, residual energy, and local node density, each node in the cluster calculates its own priority. The node with the highest priority is selected as the cluster head. Our proposal is compared with TSC,MH-TSC,SEECP,DREEP and LEACH. Experimental results show that the proposed algorithm outperforms these algorithms in terms of network stability and network lifetime.INDEX TERMS wireless sensor networks, sectors, energy efficiency, clustering.

“…The outcomes demonstrate how well this strategy may cut down on the network's energy usage. Additionally, Zheng, Zhao, Zhang, Sun, and Gao (2022) built an ellipse monitoring area where the moving target caused real-time changes to the area's size, shape, number of nodes, and working nodes. The size and form of an elliptical monitoring area were predicted using the extended kalman filter (EKF), two-step linearization, and the linearized nonlinear dynamic state.…”

“…Network nodes are commonly placed in challenging and hazardous environments, require frequent maintenance, and have a finite amount of energy they can transport. When nodes run out of energy, they die, making it impossible for them to reliably detect and track targets which makes the network's monitoring performance declines (Zheng, Zhao, Zhang, Sun, & Gao, 2022). In spite of the challenges of low power resources associated with sensor nodes, the lifetime of WSNs is always a crucial concern (Khan, Shiraz, Shaheen, Butt, Akhtar, Khan, & Changda, 2021).…”
