Closing the gap in the capacity of random wireless networks via percolation theory

Patrick Thiran, Olivier Dousse

An achievable bit rate per source-destination pair in a wireless network of n randomly located nodes is determined adopting the scaling limit approach of statistical physics. It is shown that randomly scattered nodes can achieve, with high probability, the ...

Vulnerabilities in Epidemic Forwarding

Jean-Yves Le Boudec, Alaeddine El Fawal

We identify vulnerabilities in epidemic forwarding. We address broadcast applications over wireless ad-hoc networks. Epidemic forwarding employs several mechanisms such as inhibition and spread control, and each of them can be implemented using alternative ...

Secure Positioning in Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been studied mainly in a nonadversarial setting. In this paper, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Node Cooperation in Hybrid Ad hoc Networks

Jean-Pierre Hubaux, Naouel Ben Salem, Levente Buttyan

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 ...

Of Malicious Motes and Suspicious Sensors: On the Efficiency of Malicious Interference in Wireless Networks

Rachid Guerraoui, Seth Gilbert

How efficiently can a malicious device disrupt a single-hop wireless network? Imagine two honest players attempting to exchange information in the presence of a malicious adversary that can disrupt communication by jamming or overwriting messages. Assume t ...

Malware Normalization

Johannes Kinder

Malware is code designed for a malicious purpose, such as obtaining root privilege on a host. A malware detector identifies malware and thus prevents it from adversely affecting a host. In order to evade detection by malware detectors, malware writers use ...

Impact of Interferences on Connectivity in Ad Hoc Networks

Patrick Thiran, Olivier Dousse

We study the impact of interferences on the connectivity of large-scale ad-hoc networks, using percolation theory. We assume that a bi-directional connection can be set up between two nodes if the signal to noise ratio at the receiver is larger than some t ...

Managing Heterogeneous Wireless Environments via Hotspot Servers

Giovanni De Micheli

Wireless communication today supports heterogeneous wireless devices with a number of different wireless network interfaces (WNICs). A large fraction of communication is infrastructure based, so the wireless access points and hotspot servers have become mo ...

Detecting Malicious Code by Model Checking

Johannes Kinder

The ease of compiling malicious code from source code in higher programming languages has increased the volatility of malicious programs: The first appearance of a new worm in the wild is usually followed by modified versions in quick succession. As demons ...

Fuelling WiFi deployment: A reputation-based solution

Jean-Pierre Hubaux, Naouel Ben Salem

The rapid growth of WiFi over the past two years reveals the willingness of the Wireless Internet Service Providers (WISPs) to develop this technology and the interest of the users in this new service. However, the lack of unified roaming slows down the de ...
