Cognitive Radio Resource Management Using Multi - Agent Systems , Auctions and Game Theory

In the last few years, we have attested an impressive growth in wireless communication due to the popularity of smart phones and other mobile devices. Due to the emergence of application domains, such as sensor networks, smart grid control, medical wearable and embedded wireless devices, we are seeing increasing demand for unlicensed bandwidth. There has been also increasing interest from the wireless community in the use of game theory and multi-agent systems. Our aims in this article are to summarize the different uses of game theory in wireless networks and we focused on its use in cognitive radio networks, then to discuss how multi-agent systems can be applied to solve the problem of radio resource management, and finally give the results of our simulations when combining auctions theory with multi-agent systems for the negotiation between agents. Key-Words: Game theory; Wireless Networks; Cognitive radio network; Multi-agent systems; Auctions theory.
