Ultra-Wide Band (UWB) is an emerging wireless physical layer technology that uses a very large bandwidth. We are interested in finding the design objectives of the medium access (MAC, namely, power control and scheduling) and routing protocols of a multi-h ...
With the deregulation of the electricity and telecommunications markets, a great deal of new operators providing some innovative services have appeared. In the telecommunications' field, the promise of broadband Internet access with easy installation proce ...
We consider a wide-band ad-hoc network with coherent radios in a slow-fading environment, and we analyze the performance of different physical layer (PHY) and medium access (MAC) schemes in such a network. Most of the existing analysis assume that PHY is b ...
In the last twenty years, the widespread use of sensitive electronic devices has increased the interest on transients, in particular those caused by lightning (direct and/or indirect). The paper presents first shortly the developments in modeling the elect ...
We present a joint PHY/MAC architecture (DCC-MAC) for 802.15.4a-like networks based on PPM-UWB. Unlike traditional approaches it fully utilizes the specific nature of UWB to achieve high rates at low protocol complexity. It is the first MAC protocol that a ...
We propose a MAC protocol for very low radiated power (1 microwatt) ultra-wide band (UWB) mobile ad-hoc networks. Unlike traditional approaches, our protocol fully utilizes the specific nature of the physical layer of UWB. This makes it possible to reach a ...
A complete framework dealing with power line communication in medium voltage network is proposed. Based on path loss measurements, a complete characterisation of inductive couplers is performed. After a brief recall of inductive coupling techniques, we add ...
The proliferation of hotspots based on IEEE 802.11 wireless LANs brings the promise of seamless Internet access from a large number of public locations. However, as the number of users soars, so does the risk of possible misbehavior; to protect themselves, ...
In this paper, we present an efficient measurement technique for the analysis of power line communication (PLC) signals. The frequency spectrum associated with PLC signals extends from 1 MHz to 30 MHz. The proposed technique can be applied to a network con ...
IEEE 802.11 works properly only if the stations respect the MAC protocol. We show in this paper that a greedy user can substantially increase his share of bandwidth, at the expense of the other users, by slightly modifying the driver of his network adapter ...
