Participatory Sensing: Crowdsourcing Data from Mobile Smartphones in Urban Spaces

摘要: The recent wave of sensor-rich, Internet-enabled, smart mobile devices such as the Apple iPhone has opened door for a novel paradigm monitoring urban landscape known participatory sensing. Using this paradigm, ordinary citizens can collect multi-modal data streams from surrounding environment using their and share same existing communication infrastructure (e.g., 3G service or WiFi access points). contributed multiple participants be combined to build spatiotemporal view phenomenon interest also extract important community statistics. Given ubiquity phones high density people in metropolitan areas, sensing achieve an unprecedented level coverage both space time observing events spaces. Several exciting applications have emerged years. For example, GPS traces uploaded by drivers passengers used generate realtime traffic Similarly, street-level audio samples collected pedestrians aggregated create citywide noise map. In talk, we will provide comprehensive overview new outline major research challenges.
