Game Theory and Cognitive Radio Based Wireless Networks

Abstract

Abstract. The ability to model individual, independent decision makers whose actions potentially affect all other decision makers renders game theory particularly attractive to apply to various fields of Information technology, especially, to analyze the performance of wireless networks. In this paper, we discuss how various interactions in cognitive radio based wireless networks can be modeled as a game at different levels of protocol stack. This allows the analysis of existing protocols and resource management schemes, as well as the design of equilibrium-inducing mechanisms that provide incentives for individual users to behave in socially-constructive ways. In nutshell, this paper serves two main objectives; first, to model some of the fundamental questions on cognitive radio based wireless networks as interactive games between the nodes and second, to gain our understanding on inter-discipline research issues.

Efficient Power and Channel Allocation Strategies in Cooperative Potential Games for Cognitive Radio Sensor Networks

“…We discuss a cognitive radio sensor network, where the nodes opportunistically try to utilize unused spectrum, irrespective of the type of cognition mechanism (underlay or overlay) and the presence of cooperation at some level is critical. Typically, the numbers of available channels are limited, which results in a competitive environment and the users make every effort to optimize their own performance [1][2][3][4][5]. This competition can be proficiently modeled as a game.…”

“…Several researchers have explored the cognition phenomenon from game theoretic perspective. These include both noncooperative and cooperative games [1][2][3][4][5][8][9][10][11][12][13][14][15]. Some form of cooperation involves the use of secondary users (SUs) as relays by the primary user (PU) and setting a price for channel use [8,9].…”
