Concurrent and Parallel Transmissions are Optimal for Low Data-Rate IR- UWB Networks

The Internet of Things, emerging pervasive and sensor networks are low data-rate wireless networks with, a priori, no specific topology and no fixed infrastructure. Their primary requirements are twofold: First, low power consumption and, due to environmen ...

Optimal Design of Primary User Spectrum Management Using Stackelberg Games

Mahdad Hosseini Kamal

We consider a cognitive radio network in which a base station provides opportunistic unlicensed spectrum access for secondary base stations to transmit data to their subscribers. The primary user may decide to release some parts of its bandwidth for the us ...

Optimal Pricing Strategy for Wireless Social Community Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Seyyed Amin Mazloumian

Wireless social community operators rely on subscribers who constitute a community of users. The pricing strategy of the provided wireless access is an open problem for this new generation of wireless access providers. In this paper, using both analytical ...

Friend-to-Friend Computing: Building the Social Web at the Internet Edges

Wojciech Galuba

The current Social Web is centralized. Large information silos store all the users’ profiles, their social links and much of the other personal data. In return for the reliable service the users allow their data and activities to be data mined by the servi ...

Centrality Analysis in Vehicular Networks

Jean-Pierre Hubaux

To better understand networking and security aspects of VANETs, we have been investigating network connectivity issues and mappings of car networks to the underlying road topology. Using this mapping and various metrics based on centrality, we locate hot-s ...

Fast exclusion of errant devices from vehicular networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya

Vehicular networks, in which cars communicate wirelessly to exchange information on traffic conditions, offer a promising way to improve road safety. Yet ensuring the correct functioning of such a system is essential: malicious or faulty devices transmitti ...

Virtual Infrastructure for Collision-Prone Wireless Networks

Seth Gilbert

Wireless ad hoc networks pose several significant challenges: devices are unreliable; deployments are unpredictable; and communication is erratic. One proposed solution is Virtual Infrastructure, an abstraction in which unpredictable and unreliable devices ...

On Data-Centric Trust Establishment in Ephemeral Ad Hoc Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya

We argue that the traditional notion of trust as a relation among entities, while useful, becomes insu±cient in ephemeral ad hoc networks. In this paper, we address the challenge of extending the traditional notion of trust to data-centric trust, that is, ...

Mobility-Centric Geocasting For Mobile Partitioned Networks

We describe our design of a geocast service for mobile partitioned networks (MPNs). We focus mainly on minimizing the delivery latency. Our approach exploits the time-stability of the collective mobility pattern. In MPNs, in contrast to MANETs, the end-to- ...
