Abstract

In this work, the performance of a distributed power control algorithm (DPCA) considering time-delay and estimation uncertainty has been investigated. Control theory concepts have been deployed aiming to derive the Foschini–Miljanic DPCA as well as to analyse their stability properties under time-varying delays and estimation uncertainty applicable to optical networks. Although delays introduce transient response for initial iterations, our numerical results have shown a suitable convergence of the transmitted power obtained with the DPCA under strong delay conditions. Furthermore, the DPCA was able to converge also under high level of uncertainty on the estimated SNIR, despite the solution quality decreasing.
