A Test-Bed for Misbehavior Detection in Mobile Ad-hoc Networks --- How Much Can Watchdogs Really Do?

Jean-Yves Le Boudec, Cédric Tissières, Sonja Buchegger

Several misbehavior detection and reputation systems have been proposed for mobile ad-hoc networks, relying on direct network observation mechanisms, so-called watchdogs. While these approaches have so far only been evaluated in simulations and restricted ...

BISS: Building Secure Routing out of an Incomplete Set of Security Associations

Jean-Pierre Hubaux, Srdan Capkun

We investigate secure routing in ad hoc networks in which security associations exist only between a subset of all pairs of nodes. We focus on source routing protocols. We show that to establish secure routes, it is in general not necessary that security a ...

Scalable routing protocols with applications to mobility

Ljubica Blazevic

In this thesis we study two routing problems related to mobility. The first problem concerns scalable multicast routing when there is a large number of multicast groups with a small number of receivers. Existing dense and sparse mode routing protocols have ...

Malice, Selfishness, and Slander in Mobile Ad-hoc Networks.

Jean-Yves Le Boudec, Sonja Buchegger

In mobile ad-hoc networks nodes need to cooperate to communicate, but there are many reasons for non-cooperation. Saving power or preventing other nodes from obstructing a service are merely selfish reasons for non-cooperation, whereas nodes may also activ ...

A Scalable Routing Method for Irregular Mobile Ad Hoc Networks

Jean-Yves Le Boudec, Ljubica Blazevic

We designed the terminode routing protoc ol with the objective to scale in large mobile ad hoc networks where the topology, or node distribution, is irregular. Our routing protocol is a combination of two protocols: Terminode Local Routing (TLR - to reach ...

Secure Routing for Mobile Ad hoc Networks

Panagiotis Papadimitratos

The emergence of the Mobile Ad Hoc Networking (MANET) technology advocates self-organized wireless interconnection of communication devices that would either extend or operate in concert with the wired networking infrastructure or, possibly, evolve to auto ...

Path Set Selection in Mobile Ad Hoc Networks

Panagiotis Papadimitratos

Topological changes in mobile ad hoc networks frequently render routing paths unusable. Such recurrent path failures have detrimental effects on the network ability to support QoS-driven services. A promising technique for addressing this problem is to use ...

Securing the Internet Routing Infrastructure

Panagiotis Papadimitratos

The unprecedented growth of the Internet over the last years, and the expectation of an even faster increase in the numbers of users and networked systems, resulted in the Internet assuming its position as a mass communication medium. At the same time, the ...

Self Organized Terminode Routing - Version 2

Jean-Yves Le Boudec, Ljubica Blazevic

We consider the problem of routing in a wide area mobile ad hoc network called Terminode Network. Routing in this network is designed with the following objectives. First, it should scale well in terms of the number of nodes and geographical coverage; seco ...
