Sensor placement in heterogeneous sensor networks
2012 12th International Conference on Control Automation Robotics & Vision (ICARCV), 2012Source 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., 2005Recently 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), 2007Mobile 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, 2009The 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

Sensor Cloud: A Cloud of Sensor Networks
2016 IEEE International Conference on Cloud Engineering Workshop (IC2EW), 2016Traditional model of computing with wireless sensors imposes restrictions on how efficiently wireless sensors can be used due to resource constraints. Newer models for interacting with wireless sensors such as Internet of Things and Sensor Cloud aim to overcome these restrictions.

Sensor-to-sensor identification of Hammerstein systems
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012Traditional system identification uses measurements of the inputs, but when these measurements are not available, alternative methods, such as blind identification, output-only identification, or operational modal analysis, must be used. Yet another method is sensor-to-sensor identification (S2SID), which estimates pseudo transfer functions whose ...

Sensor-to-sensor target association in a network of passive sensors
Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat. No.97CH36066), 2002This paper address the problem of sensor-to sensor target association in a distributed passive sensor network. If two or more targets are coplanar with two sensors, ghosts occur among the intersections of line-of-sights. To cancel these ghosts, the authors propose a new association method in which they track angles and angular rates of targets being ...

Optimal sensor scheduling of sensors in a sensor network for mobile robot navigation
2007 American Control Conference, 2007This paper examines sensor scheduling problems for multi-sensor systems when only one sensor is allowed to take a measurement at each time. In particular, this paper formulates an optimal sensor scheduling problem for mobile robot exploration and navigation using a sensor network whose sensors are placed on the ground. The sensors are position sensors,

A multi-sensor robot system comprises many diverse sources of information. The sensors of these systems take observations of a variety of disparate geometric features in the robot environment. The measurements supplied by the sensors are uncertain, partial, occasionally spurious or incorrect and often geographically or geometrically incomparable with ...

Sensor Distribution on Coverage in Sensor Networks
2012In this paper, we study the impacts of sensor node distributions on network coverage. We first show the impacts on network coverage by adopting different sensor node distributions through both analytical and simulation studies. Then, we adopt a distribution-free approach to study network coverage, in which no assumption of probability distribution of ...
