Abstract

The decentralized power control problem in a generic wireless communication system can be seen as a competition among the communication nodes. In this paper, we formulate a framework to the problem with the application of noncooperative game theory and opportunistic resource allocation concepts, where the satisfaction of Quality of Service (QoS) requirements is considered. As usual, continuous transmit power domain is assumed for derivation of the power control algorithm. However, the algorithm’s performance is evaluated in continuous and discrete transmit power domains through computer simulations.
