On Cooperative Wireless Network Secrecy

Emre Telatar, Suhas Diggavi, Etienne Perron

Given that wireless communication occurs in a shared and inherently broadcast medium, the transmissions are vulnerable to undesired eavesdropping. This occurs even when a point-to-point communication is sought, and hence a fundamental question is whether w ...

Transmission techniques for relay-interference networks

Christina Fragouli, Suhas Diggavi

In this paper we study the relay-interference wireless network, in which relay (helper) nodes are to facilitate competing information ﬂows over a wireless network. We examine this in the context of a deterministic wireless interaction model, which eliminat ...

Wireless Network Coding: Opportunities and Challenges

Christina Fragouli

Wireless networks suffer from a variety of unique problems such as low throughput, dead spots, and inadequate support for mobility. However, their characteristics such as the broadcast nature of the medium, spatial diversity, and significant data redundanc ...

Hierarchical Routing in Dynamic $\alpha$-Doubling Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

In this paper we formulate the problem of routing over dynamic networks with finite doubling dimension. This is motivated by communication in mobile wireless networks, where the communication graph topology changes over time, but has some geometric propert ...

On broadcast and agreement in mobile ad hoc networks

Yoav Sasson

This thesis studies communication and agreement protocols in wireless ad hoc networks from both theoretical and practical perspectives. The last decade has given rise to the rapid growth of wireless telecommunications such as cellular mobile phone networks ...

Indoor location for safety application using wireless networks

Phillip Tomé

This paper presents the indoor positioning research activities carried out within the scope of the Liaison project. Most of the work has been performed on WiFi location. WiFi is nowadays widely deployed in buildings such as hotels, hospitals, airports, tra ...

Island Hopping: Efficient Mobility-Assisted Forwarding in Partitioned Networks

Matthias Grossglauser, Natasa Sarafijanovic-Djukic

Mobile wireless ad hoc and sensor networks can be permanently partitioned in many interesting scenarios. This implies that instantaneous end-to-end routes do not exist. Nevertheless, when nodes are mobile, it is possible to forward messages to their destin ...

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 ...
