Robust H∞ Power and Rate Control for Uncertain Wireless Networks with Time-Varying State and Input Delays

Abstract

This paper is concerned with power and rate control for wireless networks. In the control theoretic framework, a new power and rate control system model is derived for uncertain wireless networks with time-varying delays in both state and control input. A robust power and rate controller is presented, which is designed based on the H∞ control approach with linear matrix inequality (LMI).Simulation results verify the effectiveness of the proposed algorithm.
