Indoor positioning systems have received increasing attention for supporting location-based services in indoor environments. WiFi-based indoor localization has been attractive due to its open access and low cost properties. However, the distance estimation based on received signal strength indicator (RSSI) is easily affected by the temporal and spatial

Interactive Indoor Localization on Helmet
2020We present a human-sensor interaction approach for indoor navigation, where we incorporate inertial motion unit sensors, human knowledge and human-computer interaction into the navigation process. The algorithm uses semantic representations of navigational constraints such as walls, stairs, and elevators, to correct the trajectory.

Indoor Localization with Aircraft Signals
Proceedings of the 15th ACM Conference on Embedded Network Sensor Systems, 2017The 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), 2015Indoor 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.

Indoor localization for mobile devices
Proceedings of the 11th IEEE International Conference on Networking, Sensing and Control, 2014This 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.

Sensory landmarks for indoor localization
2016 Fourth International Conference on Ubiquitous Positioning, Indoor Navigation and Location Based Services (UPINLBS), 2016Indoor 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 ...

Indoor Femtocell Interference Localization
IEEE Transactions on Wireless Communications, 2020Femtocells can extend the last-mile accessibility for the current cellular networks so as to serve more users indoors and improve the spectrum utility. However, since the indoor femtocell establishment can be ad hoc, HeNBs may also be inevitably vulnerable to the rogue-HeNB (uncoordinated or illegitimate HeNB) attack in practice.

Ultra-wideband and indoor localization
Proceedings of the 3rd Workshop on Hot Topics in Wireless, 2016Indoor 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 ...

The major challenge for accurate fingerprint-based indoor localization is the design of robust and discriminative wireless signatures. Even though WiFi RSSI signatures are widely available indoors, they vary significantly over time and are susceptible to human presence, multipath, and fading due to the high operating frequency.

A survey of indoor localization systems
2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014Nowadays, indoor and outdoor location-aware applications has been become increasingly widespread. Location information for outdoor applications is obtained from well-known systems such as GPS and GLONASS. Although there are several systems for indoor localization, there is not a consensus on them like the outdoor.
