TL;DR: This work presents a more realistic version of the well known Foschini-Miljanic algorithm for distributed power control since it considers the time-delays introduced to the system due to propagation delays and proves global stability of the system in the presence of propagation delays.

TL;DR: This paper introduces contractive interference functions, a slight reformulation of the standard interference functions that guarantees existence and uniqueness of fixed-points and geometric convergence rates, and shows that many power control laws from the literature are contractive and derive, sometimes for the first time, convergence rate estimates for these algorithms.

TL;DR: A set of conditions for establishing delay-independent stability and bounding the decay rate of a significant class of nonlinear positive systems which includes positive linear systems as a special case is presented.

TL;DR: A universal lower bound on the mean square error of any estimator of time-varying multidimensional Gauss-Markov processes in terms of conditional mutual information is derived.

TL;DR: This is the first work for which asymptotic convergence of consensus is proven for general linear MASs with arbitrary heterogeneous delays, and a distributed predictive observer is proposed to estimate the consensus tracking error and to construct the control input that does not involve any integral term.
