Title:

A robust framework for optimal sensor placement for source localisation techniques

Abstract:

In this talk, I will focus on the problem of finding optimal sensor locations for source localization techniques based on either time of arrival (TOA) or received signal strength (RSS) measurements. Specifically, I will consider the design problem which assumes a region where the source is likely to be present and focus on two cost functions: the former relies on the trace/determinant of CRB averaged over a grid of points resulting from the sampling of the surveillance area (shortly average CRB), whereas, the latter leverages the maximum trace/determinant of CRB over the mentioned grid (shortly worst-case CRB). Moreover, each sensor position is constrained to lie within a pre-specified set (deployment constraint set). For the aforementioned problem I will discuss an optimization framework based on block majorization-minimization to deal with both the design paradigms. Finally, through various numerical simulations, I will show the effectiveness of the developed resource allocation policies.
