Dynamic sensor tasking in heterogeneous, mobile sensor networks
Modern sensor environments often attempt to combine several sensors into a single sensor network. The nodes of this network are generally heterogeneous and may vary with respect to sensor complexity, sensor operational modes, power costs and other salient features. Optimization in this environment …

SENSOR MANAGEMENT FOR LOCALIZATION AND TRACKING IN WIRELESS SENSOR NETWORKS
<p>Wireless sensor networks (WSNs) are very useful in many application areas including battlefield surveillance, environment monitoring and target tracking, industrial processes and health monitoring and control. The classical WSNs are composed of large number of densely deployed sensors, where …

Electrochemical sensor interface
… have led to the development of electrochemical sensors that utilize electrodes with a width of one micron or less. This increased sensitivity has opened up a range of new electrochemical sensing applications, allowing the technology to move beyond the confines of the laboratory and into …

Optimal sensor placement
… thesis we explore the problem of finding optimal sensor/actuator locations to achieve the minimum square error/least effort. The solution for the optimal sensor/actuator is often combinational, this means in order to solve for the solution we have to look at many parameters in the system and those …

Sensor-driven computing
… the state of its surroundings using input from sensors and can change its behaviour accordingly. Context-aware devices might personalise themselves to their current user, alter their functionality based on where they were being used, or take advantage of nearby computing and communications …

Sensor Package Analysis and Simulation for Direct Sensor-to-Satellite Links
… the design and the performance of low-power microsensors that communicate directly to a satellite or a constellation of satellites. Information is spread using pseudo noise (PN) or Barker codes. The sensors use a single circular microstrip patch element with a wide beamwidth or a miniature phased …

NAVSPASUR sensor performance study
The Naval Space Surveillance Command (NAVSPASUR) has been in existence since the late 1950's. Operating with a formidable array of three large transmitters and six receiving stations, the command has carried out the mission of surveilling and cataloging a

Clustered wireless sensor networks
… study of topology in randomly deployed wireless sensor networks (WSNs) is important in addressing the fundamental issue of stochastic coverage resulting from randomness in the deployment procedure and power management algorithms. This dissertation defines and studies clustered WSNs, WSNs whose …

Multi-Sensor Data Fusion
… such as images, videos, audio signals, sensor data, etc., can be collected by many devices. The idea of multi-sensor data fusion is to combine the data coming from different sensors to provide more accurate information than that a single sensor alone. Sensors have been proposed to …

Structural Wireless Delamination Sensor
… monitoring delamination and, ideally, to have a sensor that can continuously monitor the delamination extent. The delamination sensor proposed in this thesis (termed as Wireless Interlaminar Nano Sensor, or WINS) is an LC resonant circuit (resonant frequency fₛ = 1 MHz), and unlike prior sensors, …

Information theoretic sensor management
Sensor management may be defined as those stochastic control problems in which control values are selected to influence sensing parameters in order to maximize the utility of the resulting measurements for an underlying detection or estimation problem. While problems of this type can be formulated …

Reactive based NOx sensor
… not in line with up-coming EPA regulations. NOx sensors are required for all catalysts being developed for reducing NO, emissions. There are no commercial NO, sensors at this time. This thesis describes work to develop a sensor based on molten alkali-carbonate salts. Preliminary results in a …

Biopsy-implantable chemical sensor
… and the right dose. This thesis presents a sensor that can be implanted inside the body during a biopsy procedure and wirelessly report on the tissue environment. The sensor has direct access and can track metabolic markers, such as pH and oxygen, which have been shown to predict outcome, …

Integration of component-based frameworks with sensor modeling languages for the sensor web
… this thesis is to develop an easily modifiable sensor system. To achieve this goal SensorML (an XML based sensor language) is combined with Java Beans (a component model language). An important part of SensorML is its process model. Each sensor in the real world is depicted in SensorML by a …
