In a typical mobile-radio situation one station is fixed in position while the other is moving, usually in such a way that the direct line between transmitter and receiver is obstructed by building
A wireless call in a cellular network requires the cooperation of a cell phone or other wireless enabled device and a dynamic set of base stations, antennas, and other network elements, with contro

A reflectarray antenna in Ka-band is currently developed under the French research project ARRESAT.
In today's Self-Organizing Networks (SONs) we differentiate between closed-loop functions, which have a predefined absolute goal, and such that form an action plan that achieves a high expected uti
A stochastic conjugate gradient method for approximation of a function is proposed.
In a wireless network composed of randomly scattered nodes, the characterization of the distribution of the best signal quality received from a group of nodes is of primary importance for many netw
We propose a quantitative model for dialog systems that can be used for learning the dialog strategy.
We consider a stochastic network with mobile users in a heavy traffic regime.
Three stochastic programming techniques which incorporate uncertain demands in linear programs are discussed. Although the techniques can be combined they are defined separately.
