Indoor map is a fundamental element of indoor location-based services (ILBS). However,
traditional indoor map** techniques are labor-intensive and time-consuming. The …

Traditional WiFi positioning relies on a predefined radio map, which is labor-intensive and
time-consuming for professionals. Recently, crowdsourcing has emerged as a promising …

Simultaneous localization and map** (SLAM) has been extensively researched in past
years particularly with regard to range-based or visual-based sensors. Instead of deploying …

Individuals' indoor trajectories can be reconstructed with sensing data for indoor navigation.
However, the movement uncertainty of such reconstructed indoor trajectories has seldom …

The construction of routable digital maps based on trajectory data has attracted a lot of
attention, especially in recent years, with the ease and cheapness of collecting the required …

This paper proposes to learn the graph of accessible indoor routes by crowd-sourcing
inertial sensor data from mobile phones. The inertial sensor data collected by each phone is …

In a global world, the human population invariably increases while resources gradually
