Abstract:
Due to the rapid development of mobile and ad hoc communication technology, research on extracting social contexts including the movement and density of pedestrians has also emerged in recent years. This study explores methods to extract pedestrian flows in a distributive manner from Bluetooth detection logs. Bluetooth devices are widely installed in mobile equipment such as laptops, tablet PCs, cell phones and PDAs, which pedestrians carry with them in daily life. The results of experiments have revealed that detection logs implicitly record traces of surrounding pedestrian flows, which might provide possibilities to analyze and distinguish pedestrian flow patterns in various situations. Moreover, the paper discusses the data management system on a serverless ad hoc network, including methods for interpolating detections in order to pick up missing devices and configurating a range query designated to gather data within the geographical range. While examining problems to be faced with technological changes, several possible scenarios are also presented for feasible applications.
