Title

IMPROVEMENT IN THE ENERGY EFFICIENCY BY DYNAMIC CHANNEL IN COGNITIVE RADIO SENSOR NETWORKS

Abstract

Wireless sensor networks operating in the license free spectrum suffer from uncontrolled interference as those spectrum bands become increasingly crowded. The emerging cognitive radio sensor networks (CRSNs) provide a promising solution to address this challenge by enabling sensor nodes to opportunistically access licensed channels. However, since sensor nodes have to consume considerable energy to support Cognitive Radio functionalities, such as channel sensing and switching, the opportunistic channel accessing should be carefully devised for improving the energy efficiency in CRSN. Here investigation of the dynamic channel accessing problem is done to improve the energy efficiency for a clustered CRSN. Under the primary user’s protection requirement, the resource allocation issues to maximize the energy efficiency of utilizing a licensed channel for intra-cluster and inter-cluster data transmission, respectively. Moreover, with the consideration of the energy consumption in channel sensing and switching, the further investigation are done to check the condition like when sensor nodes should sense and switch to a licensed channel for improving the energy efficiency.
