Power Control for Cognitive Radio Networks: A Game Theoretic Approach

Abstract In communication industry one of the most rapidly growing area is wireless technology and its applications. The efficient access to radio spectrum a requirement make this feasible for users that are running multimedia applications establishing real-time connections on an already overcrowded spectrum. recent times cognitive radios (CR) becoming prime candidates improved utilization available unlicensed secondary share with primary licensed user in such manners interference at does not increase from predefined threshold. paper, we propose algorithm address power control problem CR networks. proposed solution models system non-cooperative game, which each player maximize utility competitive environment. simulation results shows improves performance network terms high SINR low consumption.
