We consider the question of what performance metric to maximize when designing ad hoc wireless network protocols such as routing or MAC. We focus on maximizing rates under battery-lifetime and power constraints. Commonly used metrics are total capacity (in ...
This paper presents a new physical layer demonstrator for Optical Local Area Network. It offers a large total capacity to a large number of connected nodes without requiring optical amplifiers and achieves high modularity and scalability. A new multichanne ...
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 ...
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, ...
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 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 ...
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 ...
