Feedback can considerably simplify the task of approaching and achieving the performance limits predicted by information theory. This paper determines some of the potential offered by feedback in a typical sensor network situation that could be termed moni ...

We study the distributed infrastructures required for location-independent communication between mobile agents. These infrastructures are problematic: different applications may have very different patterns of migration and communication, and require diffe ...
We consider the joint optimization of sensor placement and transmission structure for data gathering, where a given number of nodes need to be placed in a field such that the sensed data can be recon structed at a sink within specified distortion bounds wh ...
Distributed systems are the basis of widespread computing facilities enabling many of our daily life activities. Telebanking, electronic commerce, online booking-reservation, and telecommunication are examples of common services that rely on distributed sy ...
Sensors acquire data, and communicate this to an interested party. The arising coding problem is often split into two parts: First, the sensors compress their respective acquired signals, potentially applying the concepts of distributed source coding. Then ...
Virtual private network design deals with the reservation of capacities in a network, such that the nodes can share communication. Each node in the network has associated upper bounds on the amount of flow that it can send to the network and receive from t ...
The present communication is based on the research undertaken by the author and whose principal results are detailed in its thesis entitled « Choice of alternatives of road infrastructures : multicriteria methods » like on the prospects offered by this one ...
For a class of sensor networks, the task is to monitor an underlying
physical phenomenon over space and time through a
noisy observation process. The sensors can communicate back
to a data collector over a noisy channel. The key parameters
in such a se ...

This thesis is concerned with problems in decentralized communication in large networks. Namely, we address the problems of joint rate allocation and transmission of data sources measured at nodes, and of controlling the multiple access of sources to a sha ...
