Beyond the Grid: Optimization of Sensor Networks through Hybrid PSO-GA Cluster Head Selection

Problem Definition

The current state of wireless sensor networks presents several key limitations and problems that hinder their effectiveness and lifespan. Researchers have introduced various approaches to address these issues, yet there are significant pain points that remain unaddressed. One major limitation is the random deployment of nodes, leading to uneven energy consumption as some nodes are forced to travel longer distances for data transmission. This results in premature energy depletion and node death, impacting the overall network performance. Furthermore, the selection of Cluster Heads (CH) in the network is typically based solely on physical factors, neglecting the crucial aspect of node trust.

This oversight may compromise the security and reliability of data transmission within the network. Another critical drawback is the lack of holistic evaluation in current models, as they struggle with the complexity of assessing multiple parameters simultaneously. As a result, existing systems have failed to demonstrate significant improvements in network lifespan. These challenges underscore the urgent need for a more comprehensive and efficient approach to managing wireless sensor networks. The deficiencies in current systems call for a novel solution that addresses the limitations identified through a thorough literature review and analysis of the existing research.

Objective

The objective of this project is to develop a hybrid optimization-based clustering approach for wireless sensor networks to address limitations in existing research. This approach aims to achieve uniform deployment of nodes, minimize energy consumption during data transmission, incorporate multiple Quality of Service parameters, and consider node trust in selecting cluster heads. By utilizing a hybrid Particle Swarm Optimization and Genetic Algorithm approach, the system will optimize parameter evaluation and selection to improve network efficiency and performance. Through thorough analysis and evaluation, the system aims to demonstrate effectiveness in optimizing resource utilization and prolonging the lifespan of grid-based sensor networks.

Proposed Work

To address the limitations identified in existing research on improving the lifespan of wireless sensor networks, this project aims to propose a hybrid optimization-based clustering approach. The focus will be on achieving uniform deployment of nodes in the sensing region to minimize energy consumption during data transmission. Additionally, the project will incorporate multiple Quality of Service (QoS) parameters in the clustering process to further enhance network performance. By considering factors such as hop count, initial energy, communication power, number of delayed packets, packets received, and node trust in the selection of cluster heads (CH), the proposed approach aims to improve the overall network lifespan. To manage the complexity of evaluating these parameters and determining their weightage in CH selection, a hybrid Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) approach will be implemented.

This hybridization will enable the system to iteratively analyze different weightage configurations to optimize the selection process and enhance network efficiency. Through thorough analysis and evaluation using various grid configurations, the proposed system will demonstrate its effectiveness in optimizing resource utilization and improving network performance in grid-based sensor networks.
