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 ...
As a component of the intelligent transportation system (ITS) and one of the concrete applications of mobile ad hoc networks, inter-vehicle communication (IVC) has attracted research attention from both the academia and industry of, notably, US, EU, and Ja ...

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 ...

We consider the problem of routing in a wide area mobile ad hoc network called Terminode Network. Routing in this network is designed with the following objectives. First, it should scale well in terms of the number of nodes and geographical coverage; seco ...

The performance of the consensus algorithm running on FDDI N. Sergent This paper presents an application of Hierarchical Coloured Timed Petri Nets to the modelling and the performance evaluation of a distributed consensus algorithm. We took a top down modu ...
We propose a new optical physical layer and protocol for optical Load Area Networks (LANs), which allow a large number of hosts to be connected while offering a large capacity and exhibiting a high degree of modularity and scalability. The physical layer o ...
Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...
One of the activities of the ACTS project EXPERT is to perform trials demonstrating the use of advancedResource Management and Routing (RMR) algorithms in ATM networks. The RMR model chosen for those trials is based on the Virtual Trunk (VT) concept. In AT ...
Fiber Distributed Data Interface (FDDI) is a high speed local area network operating at 100Mbps using a fiber optic ring transmission medium. The purpose of this paper is to build a Petri net model for the FDDI media access control (MAC) protocol. This mod ...
