Optimal cluster head election for efficient resource discovery mechanism in wireless sensor networks

Abstract

In this paper, we establish a relationship between resource discovery protocol and cluster head election procedure. While doing so, we propose a multi-resource-criteria cluster head election mechanism that reduces the computational and communication overhead incurred in resource discovery. The consequent resource discovery protocol thus necessitates a minimalist exchange of information that we provide through custom packet formats and message flows. The extent of improvement thus achieved in the proposed protocol over existing resource discovery mechanisms is shown by performance evaluation.
