认知无线网络中一种非合作博弈功率控制算法
A Power Control Algorithm Based on Non-cooperative Game Theory for Cognitive Radio Networks
摘要
Abstract
To deal with the problems of interference and large power-consumption in the existing power control algorithms,a new utility function is proposed and then a novel power control algorithm based on non-cooperative game theory is deduced. Firstly, the cost factors for signal-to-interference-noise ratio ( SINR) and power are set respectively,and channel status is introduced into the cost factors so as to con-trol transmission power reasonably and reduce the interference among users. Then, the existence and u-niqueness of the Nash Equilibrium( NE) in the utility function are proved. Finally,the flowchart of the pro-posed algorithm is presented. Simulation results show that,compared with Nash algorithm,the proposed one can reduce the power consumption effectively and achieve better anti-noise effect;compared with Koskie-Gajic(K-G)algorithm,the proposed one ensures the user's SINR to meet the required threshold value and improves the total throughput.关键词
