Game-theoretic delay-sensitive multirate power control for cdma wireless networks with variable path loss

A stochastic game-theoretic framework for calculating transmit power strategies for nodes in a competitive CDMA wireless network is presented. Unlike traditional game-theoretic power control, delay sensitivity is explicitly included. Stationary Nash equilibria that are a function of congestion and that allow for multirate transmission are determined. In both static path loss and dynamic shadowing path loss environments, the stochastic game equilibria calculated compare very favorably to traditional single-agent and often approach the performance of centralized optimization
