Adaptive fault-tolerant power and rate control for wireless networks with transmitter failures and uncertainties

Abstract

This paper considers adaptive fault-tolerant power and rate control for wireless communication networks with transmitter faults, parameter uncertainties and bounded external disturbances. The adaptive fault-tolerant controller parameters are updated automatically through the on-line estimation of eventual faults to compensate for the fault effect on the network. It is proved that the resulting adaptive closed-loop system is uniformly bounded stable based on Lyapunov approach. Simulation results are given to demonstrate the effectiveness of the proposed controller.
