MobiRoute: Routing towards a Mobile Sink for Improving Lifetime in Sensor Networks

Jean-Pierre Hubaux, Matthias Grossglauser, Jun Luo, Jacques Panchard

Improving network lifetime is an important issue involved in every aspect of the design and deployment of wireless sensor networks. There is a recent research trend of studying the application of a mobile sink to transport (rather than let the sensor nodes ...

Data Management for a Smart Earth: The Swiss NCCR-MICS initiative

Karl Aberer

The Swiss National Competence Center for Research in mobile Information and Communication Systems (NCCR-MICS or MICS) is one of several research initiatives sponsored by the Swiss National Science Foundation to promote long term research projects in areas ...

TinyNode: A Comprehensive Platform for Wireless Sensor Network Applications

Laurent Fabre, Henri Julien Dubois-Ferrière, Roger Meier, Pierre Métrailler

We introduce the TinyNode platform for wireless sensor networks. Supporting both research and industrial deployments, the platform offers communication ranges that exceed current platforms by a factor of 3 to 5, while consuming similar energy. It comes wit ...

A Robust Signal Detection Method for Ultra Wide Band (UWB) Networks with Uncontrolled Interference

Jean-Yves Le Boudec, Alaeddine El Fawal

We propose a novel detection method for non-coherent synchronization (signal acquisition) in multi-user UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) that occurs in some ad-hoc networks where concurrent transmis ...

Secure Data Communication in Mobile Ad Hoc Networks

Panagiotis Papadimitratos

We address the problem of secure and fault-tolerant communication in the presence of adversaries across a multihop wireless network with frequently changing topology. To effectively cope with arbitrary malicious disruption of data transmissions, we propose ...

Rating of Routing by Redundancy Overall Need

Emin Gabrielyan

Thanks to the large buffering time of off-line streaming applications, erasure resilient Forward Error Correction (FEC) codes can improve the reliability of communication particularly well. However real-time streaming puts hard restrictions on the buffer s ...

Global Sensor Networks

Karl Aberer, Manfred Hauswirth, Ali Salehi

The availability of cheap and smart wireless sensing devices provides unprecedented possibilities to monitor the physical world. On the technical side these devices introduce several original research problems, many of them related to the integration of th ...

A cross-layer design of wireless ad-hoc networks

We consider a cross-layer design of wireless ad-hoc networks. Traditional networking approaches optimize separately each of the three layers: physical layer, medium access and routing. This may lead to largely suboptimal network designs. In this work, we p ...

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 ...
