Sensors and Sensor Networks

2009
Sensors are essential devices in many industrial applications such as factory automation, digital appliances, aircraft/automotive applications, environmental monitoring, and system diagnostics. The main role of those sensors is to measure changes of physical quantities of surroundings.

From Sensors to Sensor Systems

2010
A new electric/electronic (E/E) vehicle architecture is proposed introducing a flexible sensor node (SN) concept. A SN collects signals from distributed sensors, calculates physical quantities out of the raw sensor data and provides the information to all vehicle functions connected to the node.

Computational image sensor for on sensor compression

IEEE Transactions on Electron Devices, 1997
In this paper, we propose novel image sensors which compress image signal. By making use of very fast analog processing on the imager plane, the compression sensor can significantly reduce the amount of pixel data output from the sensor. The proposed sensor is intended to overcome the communication bottle neck for high pixel rate imaging such as high ...

Sink-to-sensors reliability in sensor networks

ACM SIGMOBILE Mobile Computing and Communications Review, 2003
The issue of relability, thus far, has not been addressed throughly to any extent in sensor networking research. To the best of our knowledge the first such work that focused on some aspect of reliable communication in sensor networks appeared only in [1].

Sensor Cloud: A Cloud of Virtual Sensors

IEEE Software, 2014
Newer models for interacting with wireless sensors such as Internet of Things and Sensor Cloud aim to overcome restricted resources and efficiency. The Missouri S&T (science and technology) sensor cloud enables different networks, spread in a huge geographical area, to connect together and be employed simultaneously by multiple users on demand. Virtual

Minimal sensor integrity in sensor grids

Proceedings International Conference on Parallel Processing, 2002
Given the increasing importance of optimal sensor deployment for battlefield strategists, the converse problem of reacting to a particular deployment by an enemy is equally significant and not yet addressed in a quantifiable manner in the literature.

Sensor placement in heterogeneous sensor networks

2012 12th International Conference on Control Automation Robotics & Vision (ICARCV), 2012
Source localization is an important application of wireless sensor networks (WSNs). Many types of sensors can be used for source localization, e.g. range-only sensors, bearing-only sensors and time-of-arrival (TOA) sensors, etc. It is well known that the relative sensor-source geometry can significantly affect the performance of any particular ...

Sensor relocation in mobile sensor networks

Proceedings IEEE 24th Annual Joint Conference of the IEEE Computer and Communications Societies., 2005
Recently there has been a great deal of research on using mobility in sensor networks to assist in the initial deployment of nodes. Mobile sensors are useful in this environment because they can move to locations that meet sensing coverage requirements. This paper explores the motion capability to relocate sensors to deal with sensor failure or respond

Demo: Sensor Relocation with Mobile Sensors

2007 Fourth Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services (MobiQuitous), 2007
Mobile sensors are useful in many environments because they can move to increase the sensing coverage. In this paper, we present a mobile sensor prototype in which the Mica2 sensor node is used to control the movement of the robot built with commercial off-the-shelf (COTS) components.

Recovery of Sensors in Wireless Sensor Networks

2009 Fifth International Joint Conference on INC, IMS and IDC, 2009
The failure in cluster at a high level can bring up great damages to the system in wireless sensor networks where clustering techniques are used. Certain methods have been reported in the literature in recovering the sensors from a failure cluster. One of the most important methods is to recover the sensors in run-time and without clustering. But it is
