Discovering Human Routines from Cell Phone Data with Topic Models

We present a framework to automatically discover people's routines from information extracted by cell phones. The framework is built from a probabilistic topic model learned on novel bag type representations of activity-related cues (location, proximity an ...

On the Performance of Random Linear Network Coding in Relay Networks

Ramin Khalili

We compare the reliability performance gain of Random Linear Network Coding (RLNC) with Automatic Repeat Request (ARQ) for a wireless relay network taking into account overhead and complexity of feedback mechanism as well as overhead due to encoding vector ...

Wireless Network Secrecy with Public Feedback

Emre Telatar, Suhas Diggavi, Etienne Perron

In this paper we consider secret communication between two special nodes ("source" and "destination") in a wireless network with authenticated relays: the message communicated to the destination is to be kept information-theoretically (unconditionally) sec ...

Statistical Analysis of Impulse Radio Ultra-Wideband Multi User Interference based on Measurements

Jean-Yves Le Boudec, John Farserotu, Hai Zhan

Multiuser interference (MUI) statistical models for impulse radio ultra-wideband (IR-UWB) systems can be an important in providing an accurate estimate of the channel state. As such, it can have a major impact on the overall system performance. In the lite ...

Virtual Infrastructure for Collision-Prone Wireless Networks

Seth Gilbert

Wireless ad hoc networks pose several significant challenges: devices are unreliable; deployments are unpredictable; and communication is erratic. One proposed solution is Virtual Infrastructure, an abstraction in which unpredictable and unreliable devices ...

A 7.5mA 500 MHz UWB receiver based on super-regenerative principle

Catherine Dehollain, Michel Declercq

Low power impulse radio-ultra wide band(IR-UWB) receivers have potential application in the area of wireless sensor networks. In this paper the possibility of super-regenerative receivers for pulse detection is demonstrated. The super-regenerative receiver ...

Managing Impulsive Interference in Impulse Radio UWB Networks

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Wireless sensor networks are ideally built on low-cost, low-complexity nodes that have a low power consumption to guarantee a long network lifetime. These are all properties that can potentially be achieved with impulse radio ultra-wide band (IR-UWB). In a ...

An Architecture for Wireless Simulation in NS-2 Applied to Impulse-Radio Ultra-Wide Band Networks

Jean-Yves Le Boudec, Ruben Merz, Jörg Widmer

We present an architecture for implementing a wireless physical layer in a packet-based network simulator. We integrate this architecture in the popular ns-2 network simulator and use it to implement an impulse-radio ultra-wide band (IR-UWB) physical layer ...
