Sensor Network Design for Estimation of Spatially Distributed Processes ?
In a typical moving contaminating source identification problem, after some type of biological or chemical contamination has occurred, there is a developing cloud of dangerous or toxic material. Its evolution is governed by partial differential equations which include diffusion and transport phenomena. A number of mobile sensors can be deployed in the spatial area to form a sensor network and m...
متن کاملSensor network design for the estimation of spatially distributed processes
In a typical moving contaminating source identification problem, after some type of biological or chemical contamination has occurred, there is a developing cloud of dangerous or toxic material. In order to detect and localize the contamination source, a sensor network can be used. Up to now, however, approaches aiming at guaranteeing a dense region coverage or satisfactory network connectivity...
متن کاملEstimation of Spatially Distributed Processes Using Mobile Spatially Distributed Sensor Network
The problem of estimating a spatially distributed process described by a partial differential equation (PDE), whose observations are contaminated by a zero mean Gaussian noise, is considered in this work. The basic premise of this work is that a set of mobile sensors achieve better estimation performance than a set of immobile sensors. To enhance the performance of the state estimator, a networ...
متن کاملDistributed scheduling of sensor networks for identification of spatio-temporal processes
An approach to determine a scheduling policy for a sensor network monitoring some spatial domain in order to identify unknown parameters of a distributed system is discussed. Given a finite number of possible sites at which sensors are located, the activation schedule for scanning sensors is provided so as to maximize a criterion defined on the Fisher information matrix associated with the esti...
متن کاملScheduling for Distributed Sensor Networks
We examine the problem of distributed estimation when only one sensor can take a measurement per time step. The measurements are then exchanged among the sensors. The problem is motivated by the use of sonar range-finders used by the vehicles on the Caltech Multi-Vehicle Wireless Testbed. We solve for the optimal recursive estimation algorithm when the sensor switching schedule is given. Then w...
