Performance Improvement of Wireless Link Reliability in The Context of Cognitive Radio

Abstract

Cognitive radio is a software radio whose control processes leverage situational knowledge and intelligent processing to work towards achieving some goal related to the needs of the user, application, and/or network. Cognitive radio is born of the need to introduce intelligence and flexibility in managing spectrum resources that become increasingly valuable with the rapid proliferation of standards and radio services. In this paper, we propose a new approach which uses the cognitive radio for improving wireless link reliability. We show through experimentation the interest of our approach.
