Fire Detection and Localization Using Wireless Sensor Networks

Martin Hasler, Alireza Khadivi

A Wireless Sensor Network (WSN) is a network of usually a large number of small sensor nodes that are wirelessly connected to each other in order to remotely monitor an environment or phenomena. Sensor nodes use the data aggregation method as an effective ...

A Randomized Countermeasure Against Parasitic Adversaries in Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. In this paper, we first identify a typical attacker, called parasitic adversary, who seeks to exploit sensor networks by obtaining mea ...

Forest fire localization using distributed algorithms in wireless sensor networks

Martin Hasler, Alireza Khadivi, Leonidas Georgopoulos

The fire localization using a distributed consensus finding algorithm in a wireless sensor network is described. The fire is circumscribed by a circle. The information is available at all sensor nodes that are alive, which makes it robust against failures ...

A Practical Secure Neighbor Verification Protocol for Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Reza Shokri, Marcin Poturalski, Gaël Ravot

Wireless networking relies on a fundamental building block, neighbor discovery (ND). The nature of wireless communications, however, makes attacks against ND easy: An adversary can simply replay or relay (wormhole) packets across the network and mislead di ...

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 ...

Wireless sensor networks for marginal farming in India

Jacques Panchard

In this dissertation, we explore the potential of wireless sensor networks (WSNs) in an original context, the small agriculture of Developing Countries (DCs). Our goal is to confront an emerging technology with a concrete problem of world-wide dimensions, ...

Wireless sensor networks for applied research on rain-fed farming in India: an exploratory user experiment

Jacques Panchard

This document describes a user experiment that was conducted between October 2007 and February 2008 around a wireless sensor network for rain-fed agriculture. The experiment was organized jointly by UAS, the CK Trust and the EPFL. The participants came fro ...
