Collaborative WiFi Fingerprinting Using Sensor-Based Navigation on Smartphones

Collaborative WiFi Fingerprinting Using Sensor-Based Navigation on Smartphones

This paper presents a method that trains the WiFi fingerprint database using sensor-based navigation solutions. Since micro-electromechanical systems (MEMS) sensors provide only a short-term accuracy but suffer from the accuracy degradation with time, we restrict the time length of available indoor navigation trajectories, and conduct post-processing to improve the sensor-based navigation solut...

Context-Aware Personal Navigation Using Embedded Sensor Fusion in Smartphones

Context-awareness is an interesting topic in mobile navigation scenarios where the context of the application is highly dynamic. Using context-aware computing, navigation services consider the situation of user, not only in the design process, but in real time while the device is in use. The basic idea is that mobile navigation services can provide different services based on different contexts...

Weighted Fingerprinting Localization based on a Multichannel WiFi Map

WiFi localization based on fingerprinting method became popular during last decade. However, collecting information to construct a WiFi signal map is challenging due to high cost. We assume that it is possible to gather such information with cheap cost using crowd sourcing with smartphones. Each user’s current location is estimated by either GPS, WiFi, radio cell signals or manually set by the ...

INDOOR NAVIGATION SYSTEMS BASED ON iBEACON FINGERPRINTING

Evaluation of fingerprinting-based WiFi indoor localization coexisted with Bluetooth

WiFi and Bluetooth are two most commonly used short range wireless communication technologies. Recent years, with increasing number of WiFi and Bluetooth mobile terminals, tags, and other devices, a demand for integration and coexistence of these two technologies including their positioning function is booming. In this paper, we firstly investigate the interferences between WiFi and Bluetooth s...
