Maximizing Network Coverage and Energy Efficiency in Wireless Sensor Networks Using Optimization Algorithms and Uniform Node Deployment.

Problem Definition

The existing literature on Wireless Sensor Networks (WSNs) has highlighted several key limitations and problems that affect the lifespan and efficiency of these networks. While previous research has focused on efficient Cluster Head (CH) selection and communication techniques, there is a noticeable gap in addressing the issue of uniform node deployment in WSNs. The current models tend to deploy nodes randomly, leading to uneven distribution across the sensing region. As a result, CHs are forced to travel longer distances to collect data from nodes, leading to increased energy consumption and reduced network lifespan. This communication lag ultimately hinders the overall performance of the network.

To address these shortcomings and improve the functionality of WSNs, a new approach must be developed that focuses on optimizing node deployment to enhance the lifespan of the wireless network.

Objective

The objective of this study is to address the issue of uneven distribution of nodes in Wireless Sensor Networks (WSNs) by proposing a novel approach that focuses on optimizing node deployment to enhance the network's lifespan and efficiency. By utilizing Delaunay for holes detection and optimization algorithms such as Particle Swarm Optimization (PSO), Whale Optimization Algorithm (WOA), and Teaching Learning based Optimization (TLBO), the goal is to reduce communication gaps, improve network energy efficiency, and enhance network coverage. By selecting cluster heads (CH) based on the LEACH algorithm and deploying nodes uniformly in the sensing region, the proposed approach aims to overcome the limitations of traditional WSN models and improve the overall performance of WSNs.

Proposed Work

After analyzing the literature on wireless sensor networks (WSNs), it is evident that the uneven distribution of nodes in the sensing region leads to communication holes, resulting in high energy consumption and decreased network lifespan. To address this issue, the proposed work aims to design a novel WSN model with uniformly deployed nodes. By using Delaunay for holes detection and optimization algorithms such as Particle Swarm Optimization (PSO), Whale Optimization Algorithm (WOA), and Teaching Learning based Optimization (TLBO), the goal is to reduce communication gaps and improve network energy efficiency. The proposed approach focuses on selecting cluster heads (CH) based on the basic LEACH algorithm and deploying nodes uniformly in the sensing region to enhance network coverage and lifespan. By utilizing optimization algorithms individually, the effectiveness of each algorithm in reducing communication holes will be analyzed, with the ultimate objective of enhancing the overall performance of the wireless network.

The rationale behind choosing the Delaunay algorithm for holes detection and optimization algorithms for uniform node deployment lies in their ability to address the specific challenges faced by traditional WSN models. By employing Delaunay triangulation in MATLAB, the proposed work seeks to accurately identify communication gaps in the network, which facilitates the deployment of nodes in a uniform manner. The use of PSO, WOA, and TLBO optimization algorithms further enhances the network coverage by optimizing the node placement to reduce energy consumption and increase the network lifespan. By leveraging these advanced techniques, the proposed wireless network model aims to overcome the limitations of traditional models and improve the overall efficiency and performance of WSNs.
