Study on Evaluation of Internet QoS Based on Game Theory

The evaluation of Internet QoS (Quality of Service) is naturally multi-discipline. This paper examines the Internet QoS evaluation by integrating QoS index with price factor. The multinomial logit model is adopted in this paper, which is used to model the choice behaviour of users. Each service class is modelled as independently competitive entity. The goal of each service class is to maximize its own utility. Through the analysis based on noncooperative game, the conclusion is drawn that the equilibria exist between QoS index and price of each service class, and the numerical results is provided to verify the conclusion.
