A game theoretic approach for utility maximization in CDMA systems

In this paper, we provide a game theoretic approach for maximizing the utility of a carrier in a competitive market. Due to the deregulation of the telecommunications industry there is more than one service provider in any region. This gives the users the flexibility to switch their provider if they are not satisfied with their service. In this perspective, we propose a utility function based on non-cooperative game which considers the probabilities of users leaving the network. We categorize users into three classes who get differentiated services based on the price they are willing to pay. The game theoretic approach allocates resources both during service admission and burst admission. The utility function considered is from the service provider´s point of view. Our model demonstrates the impact of admitting high paying users on other users.
