Utility-based Power Control for Packet-switched Wireless Networks

In general, the problem is mathematically intractable. Using several approximation methods, the problem is reduced into tractable format and is studied both analytically and by simulations. Results show that the proposed power control scheme converges to a unique Nash equilibrium which depends on mobile's location, average packet delay requirement, traffic burstiness, and the mean and variance of the interference and background noise at mobile's base station receiver. The scheme can be easily extended to multi-class user traffic environments.
