Wireless Positioning using Ellipsoidal Constraints

Soldi, Giovanni and Jakobsson, Andreas LU orcid (2012) 20th European Signal Processing Conference, 2012 p.190-194
Abstract
Indoor location-based positioning systems have attracted notable interest during recent years for a wide range of personal

and commercial applications. As is well known, the GPS systems does not allow for accurate positioning indoors, resulting in the development of various forms of indoor positioning

techniques, mostly being based on radio frequency measurements. In this paper, we examine a novel way to reduce the

positioning error by using the notion of separating ellipsoids

in the context of received signal strength (RSS) fingerprinting.

To avoid excessive computational complexity, the algorithmis paired with the A* algorithm, exploiting mapping information of the building of interest, to... (More)

To avoid excessive computational complexity, the algorithmis paired with the A* algorithm, exploiting mapping information of the building of interest, to take into account obstacles such as walls. The proposed algorithm is evaluated on RSS measurements made in a shopping mall, and found to offer an improved positioning accuracy as compared to the Gaussian kernel approach. (Less)
