Analysis of the indoor localization game
2012 IEEE Global Communications Conference (GLOBECOM), 2012We study the non-cooperative game when many WLAN stations compete for responses from WLAN access points in order to find their positions. The main objective of the WLAN stations, which are the players in our game, is to minimize the positioning error under various constraints on power consumption and network throughput.

Compressive sensing indoor localization
2011 IEEE International Conference on Systems, Man, and Cybernetics, 2011Location based services in wireless sensor networks are quite demanding applications especially in indoors, such that accurate localization of objects and people in indoor environments has long been considered as one of important building blocks in wireless systems.

Indoor localization without the pain
Proceedings of the sixteenth annual international conference on Mobile computing and networking, 2010While WiFi-based indoor localization is attractive, the need for a significant degree of pre-deployment effort is a key challenge. In this paper, we ask the question: can we perform indoor localization with no pre-deployment effort? Our setting is an indoor space, such as an office building or a mall, with WiFi coverage but where we do not assume ...

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 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

Proceedings of the 10th international conference on Mobile systems, applications, and services, 2012
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.

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.

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.

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 ...
