When different wireless networks come in close proximity there is often a need for them to logically combine, or compose. We focus on a known research problem particularly in Ambient Networks (ANs), where heterogeneous Distributed Hash Tables (DHTs) contained in these wireless networks need to merge or divide as a result of these dynamic (de)composition(More)
The design of channel quantization codebooks for correlated broadcast channels with limited feedback is addressed. A design criterion that effectively exploits the cell statistics is proposed, based on minimizing the average sum-rate distortion in a system with joint linear beamforming and multiuser scheduling. The proposed average distortion function is(More)
In this paper, we introduce a framework that enables the deployment of autonomous services over IPv6. Then we present in detail the monitoring tool implemented as a part of the EFIPSANS project that prototypes the monitoring function of the management plane and supports the execution and verification of the elements developed during this project. The(More)
The beginning of the 1990s brought new technologies in the telecommunication networks. Asynchronous Transfer Mode (ATM) has been chosen as the transmission technology of broadband networks. The standardisation of ATM is practically finished today, the implementations are ready and the ATM equipment is largely introduced by users and service providers. At(More)
Inter-domain cooperation at control plane level offers the possibility to balance the traffic in a much more flexible way compared to the single domain Traffic Engineering (TE) methods. This solution is especially effective if the offered traffic and the network load permits to avoid congestion without recomputing the routes. Current networking technologies(More)
