Demonstration abstract: automatic radio map construction exploiting annotated walking trajectories

Chengwen Luo, Hande Hong, Mun Choon Chan

Abstract: In this demonstration, we show a radio map construction system that utilizes opportunistically sensed data contributed by users. Our free-of-infrastructure system releases users from tedious site survey and does not require prior knowledge as floor plan. By merging trajectories collected by different users, the system can automatically generate an indoor floor plan and respective radio map.
