Abstract: The cognitive radio (CR) technology allows the secondary user (SU) to share the licensed spectrum by using negotiation or cooperation methods issued from dynamic spectrum access (DSA). In this research paper we propose a method based on multi-criteria decision to deal with many parameters and after that we propose an algorithm for distributed mutual exclusion (DME) to solve the problem of channel selection. The performance of the proposed solution is evaluated through extensive simulations and achieves satisfactory results in term of processing time, response time and especially the number of exchanged messages.
Keywords: cognitive radio; multi-agent systems; dynamic spectrum access; multi-criteria decision; distributed mutual exclusion.
