Optimal sensor placement
In this 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 …

Optimal sensor placement for linear systems
The aim of sensor placement is to observe the state of a dynamical system while using only a small part of the available output information. Thus, the observer does not need sensors at every possible node of the system. We use sensor placement because it is not practical for large-scale networks, …

Near-Optimal Sensor Placement for Detection of Poisson Distributed Targets
In this dissertation, we address the problem of sensor placement for detecting uncertain targets. We model target arrivals using a Poisson process to capture the inherent randomness of event occurrences and emphasize the importance of accounting for uncertainty in the sensor placement strategy. To …

Mutual information based tracking with mobile sensors
In order to utilize mobile sensor nodes in a sensing and estimation problem, one must carefully consider the optimal placement of those sensor nodes and simultaneously account for the cost incurred in moving the sensor nodes. We present an approximate dynamic programming approach to a tracking …
