Energy efficient routing with cluster approach in wireless networks – A literature review

Abstract

This literature review examines the cluster-based approaches in wireless networks, focusing on their effectiveness in conserving energy, enhancing routing efficiency, and improving network credibility. Wireless networks are increasingly employed in various applications, from internet of things (IoT) systems to mobile ad hoc networks, where energy efficiency is critical due to the limited battery life of devices. Cluster-based techniques group nodes into clusters to optimize resource utilization, facilitating energy conservation by enabling localized communication and reducing redundant transmissions. The review explores various clustering algorithms, such as low-energy adaptive clustering hierarchy (LEACH) and hybrid energy-efficient distributed clustering (HEED), highlighting their impact on network longevity and scalability. Additionally, the study addresses the challenges of maintaining robust routing protocols within clustered networks, emphasizing the importance of reliable data transmission and node credibility to mitigate risks from malicious attacks. By synthesizing current research findings, this review provides insights into the future directions of cluster-based strategies in wireless networks, suggesting potential enhancements to ensure efficient energy management and reliable network performance.
