Mobility is an important key to many promising intelligent applications in sectors of smart cities and smart environments. As advanced wireless sensing and communication technologies are rapidly developed, an interesting technical challenge is arising -- “Can we exploit wireless data from one or multiple devices to fingerprint the locations, trajectories, and even social mobility structures of mobile devices?”. This talk will review wireless-based fingerprinting techniques from sensing, data modeling, social relationship recognition, and multi-device data fusion perspectives. First, active and passive wireless sensing techniques are reviewed. Then, our recent research outcomes in location-less trajectory modeling are introduced. Also, this talk will offer alternative techniques to find the correlation between trajectories and recognize the social structures among mobile devices without ranging and localization technologies. When multiple devices are carried by the same user, how to fuse wireless data from them to perform indoor localization is introduced.
