Beacon and beacon-less indoor assisted navigation

Abstract

In this comparative paper, we review the technologies for indoor navigation for persons with disabilities and persons that require monitoring in Ambient Assisted Living (AAL) environments. We focus on the distinction between beacon-based and beacon-less technologies. We present the categorization of indoor navigation technologies based on the approach taken to determine the location. We identify features of localization technologies that provide classification based on constraints for deployment. We also propose using floor plans to generate a navigation graph, and we give the algorithm for graph creation.
