Modeling and Measuring Performance of Data Dissemination in Opportunistic Networks

In this thesis we focus on understanding, measuring and describing the performance of Opportunistic Networks (ONs) and their applications. An “opportunistic network” is a term introduced to describe a sparse, wireless, ad hoc network with highly mobile nod ...

Traps and Pitfalls of Using Contact Traces in Performance Studies of Opportunistic Networks

Jean-Yves Le Boudec, Nikodin Ristanovic, Georgios Theodorakopoulos

Contact-based simulations are a very popular tool for the analysis of opportunistic networks. They are used for evaluation of networking metrics, for quantifying the effects of infrastructure and for the design of forwarding strategies. However, little evi ...

Tracking of Mobile Devices Through Bluetooth Contacts

Jean-Yves Le Boudec, Nikodin Ristanovic, Dang Khoa Tran

We investigate if it is possible to reconstruct a mobile phone’s mobility using its Bluetooth contacts with other mobile devices, some of which are equipped with GPS receivers. Our data mining analysis, based on two different data sets, shows that in certa ...

Adaptive Message Authentication for Vehicular Networks

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Panagiotis Papadimitratos, Nikodin Ristanovic, Georgios Theodorakopoulos

Public key cryptography can introduce significant processing delays in vehicular communication platforms. This can lead to serious performance issues, especially in the case of multi-hop Inter-Vehicle Communication. In this paper we propose Adaptive Messag ...

The age of gossip: Spatial mean-field regime

Jean-Yves Le Boudec, Nikodin Ristanovic

Disseminating a piece of information, or updates for a piece of information, has been shown to benefit greatly from simple randomized procedures, sometimes referred to as gossiping, or epidemic algorithms. Similarly, in a network where mobile nodes occasio ...
