Improving RSS-based Indoor Localization by Means of Dead-Reckoning Techniques

This paper describes a system for improving indoor localization by means of a ZigBee network, by adding extra information to the ZigBee localization engine. Typically, only RSS (Received Signal Strength) values are used in the ZigBee network while performing indoor localization. In this research, we add a Pedestrian Dead Reckoning device (PDR) to the ZigBee mobile node. This PDR device uses extra sensors such as a compass and a step detection mechanism (accelerometer) in order to provide extra localization information. The localization capabilities of the combined ZigBee and PDR system are evaluated in an indoor environment and put to the test in an indoor/outdoor field case in which the system proved to be very useful.status: publishe
