We propose a massively scalable ldquoimagingrdquo architecture for sensor networks, in
which sensor nodes act as ldquopixelsrdquo that electronically reflect (and possibly …

We consider a sensor network in which the sensors communicate at will when they have
something to report, without prior coordination with other sensors or with data collection …

We consider an imaging sensor net, in which a stationary collector node employs imaging
techniques for localization and data collection from sensor nodes without geolocation or …

Our answer to this challenge is a localization system called Spotlight. This system employs
an asymmetric architecture, in which field motes do not need any additional hardware than …

Target detection and localization is one of the key research challenges in sensor networks.
In this paper we propose a heterogeneous wireless sensor network integrating imaging and …

We introduce a class of anchoritic sensor networks, where communications between sensor
nodes are undesirable or infeasible due to, eg, harsh environments, energy constraints, or …

Received signal strength (RSS) can be used in sensor networks as a ranging measurement
for positioning and localization applications. This contribution studies the realistic situation …

We describe the application of image processing techniques for data refinement in sensor
networks, by mapping network nodes to pixels in an image. Due to their localized …

In this paper, we study the issue of defending against a wireless sensor network (WSN) that
has been deployed by a malicious enemy agent in an area of interest to us. While there can …

Location-aware networks are of great importance and interest in both civil and military
applications. This paper determines the localization accuracy of an agent, which is equipped …
