Mobility in wireless networks: friend or foe

Jun Luo

Wireless networking technologies allow computing devices to move while keeping them online, but the device mobility poses considerable technical challenges. Network designers, on the one hand, consider mobility to be harmful because it leads to dynamic and ...

Towards reliable communication and agreement in mobile ad-hoc networks

David Cavin

During the last decade, the number of wireless devices like digital organizers, mobile phones and laptop computers has drastically increased. At the same time, several technologies, like Bluetooth, GPRS, or WiFi have become mature and offer a high-performa ...

Efficient secure aggregation in VANETs

Jean-Pierre Hubaux, Maxime Raya, Adel Aziz

In VANETs, better communication efficiency can be achieved by sacrificing security and vice versa. But VANETs cannot get started without either of them. In this paper, we propose a set of mechanisms that can actually reconcile these two contradictory requi ...

On the throughput scaling of wireless relay networks

Patrick Thiran, Olivier Dousse

The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them ...

A Network Coding Approach to Energy Efficient Broadcasting: from Theory to Practice

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We show that network coding allows to realize energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus is a critic ...

A new relaying scheme for cheap wireless relay nodes

Ramin Khalili

In this paper we will propose a relaying scheme for wireless multi-hop networks. It is based on collaboration of intermediate relays at network layer to forward useful side information in place of dumbly forwarding packets. In our scheme we assume that the ...

Consensus with Unknown Participants or Fundamental Self-Organization

André Schiper, David Cavin, Yoav Sasson

We consider the problem of bootstrapping self-organized mobile ad hoc networks (MANET), i.e. reliably determining in a distributed and self- organized manner the services to be offered by each node when neither the identity nor the number of the nodes in t ...

A lower bound to the scaling behavior of sensor networks

Martin Vetterli, Michael Christoph Gastpar

For a class of sensor networks, the task is to monitor an underlying physical phenomenon over space and time through a noisy observation process. The sensors can communicate back to a data collector over a noisy channel. The key parameters in such a se ...

Secure Positioning in Sensor Networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in sensor and ad hoc networks has been studied in a non-adversarial setting. We show that most of the proposed positioning algorithms are highly vulnerable to attacks from compromised network nodes and malicious (outside) ...
