An economic model for power control in wireless CDMA data networks

Power control is one of the major challenges in radio resource management in wireless CDMA networks. Traditional power control scheme mainly concerns real-time voice services in mobile communications systems. In this paper, we present a new utility function with pricing and propose an economic model using game theory for uplink power control for data services in wireless CDMA networks. Based on the model we propose a synchronous distributed power control algorithm. Numerical simulations are conducted to demonstrate the performance of the algorithm. We investigate the pricing factor on the performance of the system. The results show the performance of convergence of the algorithm is satisfactory.
