Survey of optical indoor positioning systems
2011 International Conference on Indoor Positioning and Indoor Navigation, 2011Recent advances in CCD technologies, processing speed and image understanding have been driving the development of the camera-based positioning systems. An improved performance of optical systems has triggered image based positioning methods to become an attractive alternative for applications in industrial metrology as well as for robot- and ...

RFID-based indoor positioning system
International Journal of Radio Frequency Identification Technology and Applications, 2011In logistics supply chains, automated guided vehicles are not used owing to the lack of suitable localised positioning systems to guide them. A wide variety of technologies have been researched including vision, sensor networks and radio frequency signals, but there are still issues in cost, accuracy, line of sight and installation of these ...

Key Technologies for Indoor Positioning Systems
2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet), 2019It 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 ...

Survey on Indoor Positioning Techniques and Systems
2018Navigating different devices and human beings in indoor scene has become very crucial for number of tasks specially in automated system. The efficiency of outdoor positioning has become excellent due to the development of GPS. However lots of mass market applications require very excellent positioning capabilities in almost every environments.

Secure Crowdsourced Indoor Positioning Systems
IEEE INFOCOM 2018 - IEEE Conference on Computer Communications, 2018Indoor 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, 2009Location 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.

Bluetooth Indoor Positioning System Using Fingerprinting
2012Indoor Positioning has been an active research area in the last decade, but so far, commercial Indoor Positioning Systems (IPSs) have been sparse. The main obstacle towards widely available IPSs has been the lack of appropriate, low cost technologies, that enable indoor positioning.While Wi-Fi infrastructures are ubiquitous, consumer-oriented Wi-Fi ...

WIPS: the WiSARD Indoor Positioning System.
2013In 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.
