Infrastructure-based mobile-positioning is receiving increasing attention in the field of wireless communications. This is is due to an order issued by the Federal Communications Commission (FCC) that mandates all wireless service providers to locate an em ...
This document presents a new research domain in the area of communication systems. It is meant to be the proposal of the Communication Systems Division of EPFL and its Consortium to the National Pole of Competence of the Swiss National Fund. The expected ( ...
This paper specifies a multicast routing protocol called Distributed Core Multicast (DCM). It is intended for use within a large single Internet domain network with a very large number of small multicast groups. We present how DCM can be used to route pack ...
We present a multicast routing protocol called Distributed Core Multicast (DCM). It is intended for use within a large single Internet domain network with a very large number of multicast groups with a small number of receivers. Such a case occurs, for exa ...
The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
Position-based routing protocols forward packets in a greedy manner from source to destination without having to maintain routes through the network. Contention-based routing strategies improve upon position-based routing in that they do not even require t ...
This document presents a research agenda in the area of communication systems. It is meant to be the proposal of the Communication Systems Division of EPFL and its Consortium to the National Center of Competence in Research (NCCR) of the Swiss National Fun ...
We consider the problem of multicast routing in a large single domain network with a very large number of multicast groups with small number of receivers. Such a case occurs, for example, when multicast addresses are statically allocated to mobile hosts, a ...
Confidential information contained in the transactional data created in mobile communication systems is not very well protected. We present an approach to protect entire objects against manipulation and disclosure, which allows to retain some control over ...
