Node Cooperation in Hybrid Ad hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Naouel Ben Salem

A hybrid ad hoc network is a structure-based network that is extended using multi-hop communications. Indeed, in this kind of network, the existence of a communication link between the mobile station and the base station is not required: A mobile station t ...

Nash Equilibria of Packet Forwarding Strategies in Wireless Ad Hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Mark Felegyhazi

In self-organizing ad hoc networks, all the networking functions rely on the contribution of the participants. As a basic example, nodes have to forward packets for each other in order to enable multi-hop communication. In recent years, incentive mechanism ...

Cooperative Packet Forwarding in Multi-Domain Sensor Networks

Jean-Pierre Hubaux, Levente Buttyan, Mark Felegyhazi

Sensor networks are large scale networks of low-power devices that collaborate in order to perform a given task. The sensors are limited in battery energy, capacity and computational power. In recent years, researchers have proposed several protocols for s ...

Mobility Helps Peer-to-Peer Security

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

We propose a straightforward technique to provide peer-to-peer security in mobile networks. We show that far from being a hurdle, mobility can be exploited to set up security associations among users. We leverage on the temporary vicinity of users, during ...

Architecture for Secure and Private Vehicular Communications

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Levente Buttyan

The deployment of vehicular communication (VC) systems is strongly dependent on their security and privacy features. In this paper, we propose a security architecture for VC. The primary objectives of the architecture include the management of identities a ...
