Energy harvesting-based two-hop clustering for wireless mesh network

Abstract

The deployment of wireless mesh networks (WMNs) in numerous applications ranging from civilian to military and much more has acquired attention among researchers in recent years. A mesh is formed from tiny sensor nodes (SNs), deployed in some predefined manner which can perform task as per the need of an application. Effective utilization of energy of each SN in any network is one of the challenging task, as replacement of battery of theses nodes degrades the performance of the network. Considering this optimal energy utilization, in this paper, we have proposed a two-hop optimized clustering-based approach in WMN using energy harvesting (EH), which increases the network lifetime and stability. Sensors those are nearest to the collection point (CP) can directly communicate with the base station (BS); however, SNs those are far away from CP used the cluster-based approach for data communication. Result shows that there has been significant improvement on lifetime enhancement, and stability as compared with other state-of-the-art protocols which exist under the same category.
