Dynamic Group Monitoring in Proximity-based Mobile Social Networks


Various forms of groups exist in social interactions. In recent years, due to the increasing popularity of mobile devices such as smartphones, these dynamic groups can be monitored by exploiting the collaborative capabilities of these mobile devices. In this talk, I will first describe QueueSense, a system for collaborative recognition of queuing behavior using mobile phones. I will present a few technical details on what queuing features are extracted and how different queuing lines are partitioned. I will then describe a few highlights of our research efforts on monitoring other types of groups in mobile social networks. I will conclude with a brief discussion of our ongoing research projects in the areas of mobile wireless sensor networks, smartphone sensing, and robotic sensing.
