Wireless Social Community Networks: A Game-Theoretic Analysis

Jean-Pierre Hubaux, Julien Freudiger, Mark Felegyhazi, Peter Marbach

Wireless social community networks formed by users with a WiFi access point have been created as an alternative to traditional wireless networks that operate in the licensed spectrum. By relying on access points owned by users for access, wireless communit ...

Revocation Games in Ephemeral Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Maxime Raya

A frequently proposed solution to node misbehavior in mobile ad hoc networks is to use reputation systems. But in ephemeral networks - a new breed of mobile networks where contact times between nodes are short and neighbors change frequently - reputations ...

Wireless Sensor Networking for Rain-fed Farming Decision Support

Jean-Pierre Hubaux, Jacques Panchard, Panagiotis Papadimitratos, Sanjeev Kumar

Wireless sensor networks (WSNs) can be a valuable decision- support tool for farmers. This motivated our deployment of a WSN system to support rain-fed agriculture in India. We defined promising use cases and resolved technical challenges throughout a two- ...

Secure Neighbor Discovery in Wireless Networks: Formal Investigation of Possibility

Jean-Pierre Hubaux, Marcin Poturalski, Panagiotis Papadimitratos

Wireless communication enables a broad spectrum of applications, ranging from commodity to tactical systems. Neighbor discovery (ND), that is, determining which devices are within direct radio communication, is a building block of network protocols and app ...

Wormhole-Based Anti-Jamming Techniques in Sensor Networks

Jean-Pierre Hubaux, Srdan Capkun, Mario Cagalj

Due to their very nature, wireless sensor networks are probably the category of wireless networks most vulnerable to “radio channel jamming”-based Denial-of-Service (DoS) attacks. An adversary can easily mask the events that the sensor network should detec ...

Securing Vehicular Ad Hoc Networks

Jean-Pierre Hubaux, Maxime Raya

Vehicular networks are very likely to be deployed in the coming years and thus become the most relevant form of mobile ad hoc networks. In this paper, we address the security of these networks. We provide a detailed threat analysis and devise an appropriat ...

Efficient and Robust Pseudonymous Authentication in VANET

Jean-Pierre Hubaux, Panagiotis Papadimitratos

Effective and robust operations, as well as security and privacy are critical for the deployment of vehicular ad hoc networks (VANETs). Efficient and easy- to-manage security and privacy-enhancing mechanisms are essential for the wide-spread adoption of th ...

COMMONSense Net: A Wireless Sensor Network for Resource-Poor Agriculture in the Semiarid Areas of Developing Countries

Jean-Pierre Hubaux, Jacques Panchard

We describe the on-going design and implementation of a sensor network for agricultural management targeted at resource-poor farmers in India. Our focus on semi-arid regions led us to concentrate on water-related issues. Throughout 2004, we carried out a s ...

Efficient and Robust Secure Aggregation for Sensor Networks

Jean-Pierre Hubaux, Karl Aberer, Marcin Poturalski, Panagiotis Papadimitratos, Parisa Haghani

Wireless Sensor Networks (WSNs) rely on in-network aggregation for efficiency, however, this comes at a price: A single adversary can severely influence the outcome by contributing an arbitrary partial aggregate value. Secure in-network aggregation can det ...

Non-cooperative Multi-radio Channel Allocation in Wireless Networks

Jean-Pierre Hubaux, Mario Cagalj, Mark Felegyhazi, Shirin Saeedi Bidokhti

Channel allocation was extensively studied in the framework of cellular networks. But the emergence of new system concepts, such as cognitive radio systems, has brought this topic into the focus of research again. In this paper, we study in detail the prob ...

Architecture for Secure and Private Vehicular Communications

Jean-Pierre Hubaux, Levente Buttyan, Maxime Raya, Panagiotis Papadimitratos

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 ...

Eviction of Misbehaving and Faulty Nodes in Vehicular Networks

Jean-Pierre Hubaux, Daniel Jungels, Maxime Raya, Imad Aad, Panagiotis Papadimitratos

Vehicular Networks (VNs) are emerging, among civilian applications, as a convincing instantiation of the mobile networking technology. However, security is a critical factor and a significant challenge to be met. Misbehaving or faulty network nodes have to ...

Border Games in Cellular Networks

Jean-Pierre Hubaux, Diego Dufour, Mario Cagalj, Mark Felegyhazi

In each country today, cellular networks operate on carefully separated frequency bands. This separation is imposed by the regulators of the given country to avoid interference between these networks. But, the separation is only valid within the borders of ...

Mix-Zones for Location Privacy in Vehicular Networks

Jean-Pierre Hubaux, Julien Freudiger, Mark Felegyhazi, Maxime Raya, Panagiotis Papadimitratos

Vehicular Networks (VNs) seek to provide, among other applications, safer driving conditions. To do so, vehicles need to periodically broadcast safety messages providing precise position information to nearby vehicles. However, this frequent messaging (e.g ...

Securing Vehicular Communications

Jean-Pierre Hubaux, Maxime Raya, Panagiotis Papadimitratos

The road to a successful introduction of vehicular communications has to pass through the analysis of potential security threats and the design of a robust security architecture able to cope with these threats. In this paper, we undertake this challenge. I ...

DOMINO: Detecting MAC layer greedy behavior in IEEE 802.11 hotspots

Jean-Pierre Hubaux, Maxime Raya, Imad Aad, Alaeddine El Fawal

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 ...

How to specify and how to prove correctness of secure routing protocols for MANET

Jean-Pierre Hubaux, Panagiotis Papadimitratos

Secure routing protocols for mobile ad hoc networks have been developed recently yet, it has been unclear what are the properties they achieve, as a formal analysis of these protocols is mostly lacking. In this paper we are concerned with this problem, how ...

Wireless Operators in a Shared Spectrum

Jean-Pierre Hubaux, Mark Felegyhazi

So far, cellular networks have been operated in "private" frequency bands. But recently, several researchers and legislators have argued in favor of a more flexible and more efficient management of the spectrum, leading to the possible coexistence of sever ...
