Adaptive Power and Rate Control for Wireless Communication Networks with Nonlinear Channel Fading and Time-Varying Delay

Abstract

This paper investigates power and rate control for uncertain wireless communication networks with nonlinear channel fading and time-varying delay. A new mathematical model of power and rate control system is derived. To compensate for the effects of nonlinear channel fading, time-varying delay, and parameter uncertainty, a power and rate controller is designed based on adaptive control technique. The performance of the closed-loop system is analyzed by using Lyapunov-Krasovskii functional and linear matrix inequality. Simulation results verify the effectiveness of the proposed controller.
