Current network implementations for sensor devices require all sensors to participate in a simple multihop network. This results in an architecture that imposes an extra processing burden on the sensors, fails to take advantage of location-based information, does note provide multicast capabilities and scales

We present a natural wireless sensor network problem, which we model as a probabilistic version of the min dominating set problem. We show that this problem, being a generalization of the classical min dominating set, is NP-hard, even in bipartite graphs. We first study the complexity of probabilistic min dominating set in graphs where min dominating set is polynomial, mainly in trees and paths...

Ad-hoc networks of sensor nodes are in general semi-permanently deployed. However, the topology of such networks continuously changes over time, due to the power of some sensors wearing out, to new sensors being inserted into the network, or even due to designers moving sensors around during a network re-design phase (for example, in response to a change in the requirements of the network). In ...

As infectious disease surveillance systems expand to include digital, crowd-sourced, and social network data, public health agencies are gaining unprecedented access to high-resolution data and have an opportunity to selectively monitor informative individuals. Contact networks, which are the webs of interaction through which diseases spread, determine whether and when individuals become infect...

Nowadays, wireless sensor network which consists of numerous tiny sensors has been widely used. One of the major challenges in such networks is how to cover the sensing area effectively and maintain longer network lifetime with limited energy simultaneously. In this paper, we study hybrid sensor network which contains both static and mobile sensors. We divide monitoring area into Delaunay Trian...

Wearable physiological monitoring system consists of an array of sensors embedded into the fabric of the wearer to continuously monitor the physiological parameters and transmit wireless to a remote monitoring station. At the remote monitoring station the data is correlated to study the overall health status of the wearer. In the conventional wearable physiological monitoring system, the sensor...
