Indoor Localization with Aircraft Signals

Proceedings of the 15th ACM Conference on Embedded Network Sensor Systems, 2017
The standard method for outdoor localization is GPS, because it is globally available, relatively accurate and receivers are inexpensive. However, GPS does not work well indoors due to low signal strength. We explore a new localization approach, which uses the same principle as GPS localization, but employs signals transmitted by aircraft.

Lightweight Indoor Localization System

2015 8th IFIP Wireless and Mobile Networking Conference (WMNC), 2015
Indoor localization is an important topic for context aware applications. In particular, many applications for wireless devices can benefit from knowing the location of a user. Despite the huge effort from the research community to solve the localization problem, there is no widely accepted solution for localization in an indoor environment.

Ultra-wideband and indoor localization

Proceedings of the 3rd Workshop on Hot Topics in Wireless, 2016
Indoor localization technology is completing a generational shift, improving from meter to near-centimeter level accuracy, and shifting research priorities from improving accuracy to building scalable, deployable systems. Leading this shift are ultra-wideband (UWB) RF solutions that have demonstrated their potential for very high accuracy indoor ...

Indoor localization for mobile devices

Proceedings of the 11th IEEE International Conference on Networking, Sensing and Control, 2014
This paper proposes an indoor localization system for mobile devices in urban high-rise environments. The proposed system classifies received signal strength measured from existing Wi-Fi access points, and predicts location of mobile devices based on the measured Wi-Fi signal strength and building floor plan.

Channel learning in indoor localization

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
This work addresses the fundamental issue of online channel learning in indoor localization systems. We describe a novel algorithm for unsupervised channel learning where the path loss exponent in the Non-Line-Of-Sight (NLOS) region is adapted online while positioning.

Sensory landmarks for indoor localization

2016 Fourth International Conference on Ubiquitous Positioning, Indoor Navigation and Location Based Services (UPINLBS), 2016
Indoor localization is important for a variety of applications such as emergency response, shopping guide, and location-based services. Localization based on smartphone inertial sensors is one of the most widely-used indoor localization techniques since it can provide continuous and real-time locations without requiring additional infrastructure ...

Virtual testbed for indoor localization

International Conference on Indoor Positioning and Indoor Navigation, 2013
We present a novel, easy to use virtual testbed for the evaluation of localization algorithms. Our testbed enables researchers to easily run tests on a huge body of real world range-based indoor localization data. The data consists of a dense grid of reference points belonging to one or multiple maps.

Experimental evaluation of indoor localization algorithms

2014 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2014
In Radio Frequency (RF)-based indoor localization scenarios, localization algorithms are needed to alleviate the impact of non-line-of-sight and multipath effects on the measurements and thereby estimate the true position precisely. Several resilient lateration algorithms have been proposed in the last couple of years which claim to minimize these ...

Cooperative and heterogeneous indoor localization experiments

2013 IEEE International Conference on Communications Workshops (ICC), 2013
In this paper we present the results of real-life localization experiments performed in an unprecedented cooperative and heterogeneous wireless context. These measurements are based on ZigBee and orthogonal frequency division multiplexing (OFDM) devices, respectively endowed with receivedsignal strength indicator (RSSI) and round trip delay (RTD ...

Fast-converging indoor mapping for wireless indoor localization

2014 IEEE International Conference on Pervasive Computing and Communication Workshops (PERCOM WORKSHOPS), 2014
The construction of indoor floor plans for wireless localization with minimal deployment effort and with low cost is relevant in many ambient intelligence and mobile computing applications. Simultaneous Localization and Mapping (SLAM) is a well-known technique for solving the problem of localization of an object in an unknown environment while ...
