Key Technologies for Indoor Positioning Systems

2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet), 2019
It has always been important to know where we are in the world. In the past we used maps and compasses to find our way but today we are using GPS devices when travelling by foot, car or bike. The developments in location-based techniques and the growing usefulness of ubiquitous computing and context-dependent information have resulted in an increase ...

Secure Crowdsourced Indoor Positioning Systems

IEEE INFOCOM 2018 - IEEE Conference on Computer Communications, 2018
Indoor positioning systems (IPSes) can enable many location-based services in large indoor environments where GPS is not available or reliable. Mobile crowdsourcing is widely advocated as an effective way to construct IPS maps. This paper presents the first systematic study of security issues in crowd-sourced WiFi-based IPSes to promote security ...

Calibrating RSS-Based Indoor Positioning Systems

2009 IEEE International Conference on Wireless and Mobile Computing, Networking and Communications, 2009
Location estimation based on Received Signal Strength (RSS) is the prevalent method in indoor positioning. For RSS-based methods a massive collection of training RSS samples is needed to calibrate the positioning system and to achieve a high positioning quality.

Localization Error Analysis of Indoor Positioning System Based on UWB Measurements

International Conference on Ubiquitous and Future Networks, 2019
Ultra wide band (UWB) systems use time information instead of the popular received signal strength indication (RSSI). UWB is known for its high position accuracy in localization.

WIPS: the WiSARD Indoor Positioning System. [PDF]

, 2013
In this paper, we present a WiSARD-based system facing the problem of Indoor Positioning (IP) by taking advantage of pervasively available infrastructures (WiFi Access Points - AP). The goal is to develop a system to be used to position users in indoor environments, such as: museums, malls, factories, offshore platforms etc.
