Daily Routine Classification from Mobile Phone Data

Daniel Gatica-Perez, Katayoun Farrahi

The automatic analysis of real-life, long-term behavior and dynamics of individuals and groups from mobile sensor data constitutes an emerging and challenging domain. We present a framework to classify people's daily routines (defined by day type, and by g ...

Smart Antenna-Aided Multicarrier Transceivers for Mobile Communications

Yosef Akhtman

In spite of an immense interest from both the academic and the industrial communities, a practical multipleinput multiple-output (MIMO) transceiver architecture, capable of approaching channel capacity boundaries in realistic channel conditions remains lar ...

Wireless operators in a shared spectrum

Jean-Pierre Hubaux, Mark Felegyhazi

So far, cellular networks have been operated in "private" frequency bands. But recently, several researchers and legislators have argued in favor of a more flexible and more efficient management of the spectrum, leading to the possible coexistence of sever ...

Node Cooperation in Hybrid Ad hoc Networks

Jean-Pierre Hubaux, Naouel Ben Salem, Levente Buttyan

A hybrid ad hoc network is a structure-based network that is extended using multi-hop communications. Indeed, in this kind of network, the existence of a communication link between the mobile station and the base station is not required: A mobile station t ...

Adaptive Subchip Multipath Resolving for Wireless Location Systems

Ali H. Sayed

Reliable positioning of cellular users in a mobile environment requires accurate resolving of overlapping multipath components. However, this task is difficult due to fast channel fading conditions and data ill-conditioning, which limit the performance of ...

Joint Mobility and Routing for Lifetime Elongation in Wireless Sensor Networks

Jean-Pierre Hubaux, Jun Luo

Although many energy efficient/conserving routing protocols have been proposed for wireless sensor networks, the concentration of data traffic towards a small number of base stations remains a major threat to the network lifetime. The main reason is that t ...
