On uncoordinated wireless ad-hoc networks

Alaeddine El Fawal

Emerging pervasive wireless networks, pocket switched networks, Internet of things, vehicular networks and even sensor networks present very challenging communication circumstances. They might involve up to several hundreds of wireless devices with mobilit ...

Fundamental limits and optimal operation in large wireless networks

Ayfer Özgür Aydin

Wireless adhoc networks consist of users that want to communicate with each other over a shared wireless medium. The users have transmitting and receiving capabilities but there is no additional infrastructure for assisting communication. This is in contra ...

Neighbor Discovery in Wireless Networks and the Coupon Collector's Problem

Ramin Khalili

Neighbor discovery is one of the first steps in the initialization of a wireless ad hoc network. In this paper, we design and analyze practical algorithms for neighbor discovery in wireless networks. We first consider an ALOHA-like neighbor discovery algor ...

Source coding in sensor networks

Robert Konsbruck

Wireless sensor networks have emerged as versatile tools to monitor the evolution of physical fields over large areas by means of self-powered and low-cost sensing devices. Although their development was originally motivated by military applications, they ...

A distributed minimum-distortion routing algorithm with in-network data processing

Ramin Khalili

In many wired and wireless networks, nodes process input traffic to satisfy a network constraint (e.g., a capacity constraint) and to increase the utility of data in the output flows given these constraints. In this paper we focus on the special case in wh ...

Graphical display for annual climate-based daylight simulation

Marilyne Andersen, Magali Bodart

Due to daylight variability, a design cannot be thoroughly assessed using single-moment simulations, which is why we need dynamic performance metrics like Daylight Autonomy and Useful Daylight Illuminance. Going one step further, the annual variation in pe ...

Security and Cooperation in Wireless Networks

Jean-Pierre Hubaux, Levente Buttyan

According to most technology pundits, progress in wireless and sensor networks will lead us into a world of ubiquitous computing, in which myriads of tiny, untethered sensors and actuators will communicate with each other. Information technology will thus ...

Assessing the Challenges of Environmental Signal Processing through the SensorScope Project

Martin Vetterli, Yue Lu, Guillermo Barrenetxea Kobas, François Ingelrest

SensorScope is a collaborative project between network, signal processing, and environmental researchers that aims at providing a cheap and out-of-the-box environmental monitoring system based on a wireless sensor network. It has been successfully used in ...

SensorScope: Out-of-the-Box Environmental Monitoring

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, François Ingelrest, Olivier Couach

An important field of application for wireless sensor networks is environmental monitoring. Given the importance of potential climate changes, environmental impact on cities, and pollution, it is an application domain where sensor networks can have great i ...
