Crowd-Sourced Mobile Urban Sensing – as Deployed in Beijing
Dr. Lin Zhang, Associate Professor of Tsinghua University
Dr. Lin Zhang, Associate Professor of Tsinghua University (and currently Visiting Associate Professor at Stanford University) introduces a taxi-cab based mobile sensor network system designed for wide area urban sensing and deployed in Beijing, China.
Wide area urban sensing systems provides up-to-date, detailed observations of climate, environment, traffic and population patterns to enable government decisions about fast-paced urbanization. Two major challenges include communication capacity and sensing capability. The Beijing system addresses both challenges by crowd-sourcing the sensing tasks to a group of taxi cabs roaming in the city, and by using a store-carry-and-forward mechanism to collect the sensor data in data center for processing. Compared to static dedicated sensor networks, the system enjoys extremely low deployment costs and fairly good coverage performance. The talk includes details of the system design and also future deployment plans.
Professor Zhang received his B.S., M.S. and Ph.D. degrees from Tsinghua University; his research focuses on wireless sensor networks, distributed data processing, and information theory. He is co-author of more than 40 peer-reviewed technical papers and five U.S. or Chinese patents. Lin and his team were the winners of the IEEE/ACM SenSys 2010 Best Demo Award. Professor Zhang has worked closely with Cisco Systems since 2008 in developing MASON (Metropolitan Area Sensing and Operating Network), which is currently under consideration for possible adoption by a number of large Chinese cities.
Immediately following the session, we’ll have a short-networking reception from 5:30 – 6:15PM.
This is the fourth session in a nine week seminar series on “Green Technologies in Transportation: Recent Developments from Asia.”
