Power Control and Utility Optimization in Wireless Communication Systems
Dimitrie C. Popescu, Anthony Theodore Chronopoulos · 2005
In this paper we present an analysis of power control algorithms established over the past decade for cellular telephone systems, in conjunction with utility functions introduced recently to specify quality of service in wireless systems providing data services. These algorithms are compared with power control algorithms based on game theory established relatively recently. The analysis shows that the Nash equilibrium points to which the game theory based algorithms for power control converge are not efficient, and that better solutions are possible.
