WiFiGenius: An Accurate and Reliable WiFi-based Indoor Localization and Navigation System

چکیده
Our WiFi based Indoor Positioning System (IPS) – WiFiGenius, leverage the WiFi received signal strength (RSS) of mobile device mainly to achieve accurate and reliable indoor localization. We upgrade the firmware of the existing commercial WiFi access points (APs) to allow them to collect WiFi RSS of each mobile device. The RSS and MAC addresses of mobile devices are then sent to a location server. The location server will employ on appropriate localization algorithms we proposed [1,2] to figure out the position of each mobile device and thus its user. The deployment requirements of our system are only numbers of upgraded commercial WiFi APs which can cover the entire competition testbed, a laptop as the location server and a mobile device as the testing device. A light offline site survey will be conducted in order to construct the WiFi RSS database. Other Inertial Measurement Unit (IMU) sensors of mobile device, i.e. accelerometer, gyroscope and magnetometer, will be employed to assist and improve the performance of WiFiGenius in some particular indoor scenarios.

Indoor localization method comparison: Fingerprinting and Trilateration algorithm
Enhanced Positioning Systems (EPS) are able to supplement Global Positioning Systems (GPS) in indoor environments where GPS cannot work because of disrupted or weak signals. Most EPS are Wifi-based because Wifi is a common technology available in many indoor environments and is deployed in cost effective manner. Fingerprinting and Trilateration are the two general methods used for calculating p...

Location-based services (LBS) are services offered through a mobile device that take into account a device’s geographical location. To provide position information for these services, location is a key process. GNSS (Global Navigation Satellite System) can provide sub-meter accuracy in open-sky areas using satellite signals. However, for indoor and dense urban environments, the accuracy deterio...
متن کاملRobust Indoor Localization on a Commercial Smart Phone
This technical report outlines a system for robust indoor localization on a commercial smart-phone. Towards achieving effective localization, in the absence of GPS, we combine complementary localization algorithms of dead reckoning and Wifi signal strength fingerprinting. Dead reckoning is performed using the on-board accelerometer, magnetometer, and gyroscope sensors to detect motion and estim...
متن کاملA Smart-Phone Indoor/Outdoor Localization System
This paper depicts the operation of an integrated system designed for both outdoor and indoor localization, with special emphasis on the latter. It is demonstrated how three different methods of localization can be combined, based on WiFi access points and mobile cells. Not only there is no need to know the exact location of the access points to start using the system, but it also self-improves...
