Abstract

Wireless Cognitive Sensor Networks (WCSNs) consist of a combination of small, less energy and economical sensors. One of the major functions of these WCSNs is to sense the channels properly. The primary issue is that the sensors cannot sense the multiple channels simultaneously. So, to select cooperative sensors for sensing multiple channels simultaneously is a challenging issue. The focus should also be laid on extending the lifetime of WCSNs. In this paper, for sensing different channels within different sensing periods tunable receiver is proposed and to extend the lifetime of the sensors, systematic node selection is suggested. With node selection, adequate nodes sense the channel while all the quality restrictions are to be maintained. A subset of nodes to sense every channelis chosen in a way that the remaining energy of the sensor is balanced properly which results in extending the lifetime of the network. Simulation results are obtained to discuss the benefits of the proposed process with other sensor choosing schemes.

Keywords: Energy efficient, Lifetime maximization, Multichannel sensing.
