When we think of existing wireless sensor networks, people are out-of- the-loop they simply interact at the periphery of the network with physically embedded static sensor webs to realize small scale application-specific sensing applications (e.g., environmental sensing, industrial sensing, etc.) of interest to scientists and engineers. Looking forward we envision Internet scale sensing where a large amount of the traffic on the network is sensor data and a large amount of applications used every day by people integrate sensing, fusion, and actuation in some form or another. Sensing will be transformed from mostly static and physically embedded to mostly mobile and people-centric - putting people back in the loop. The MetroSense project at Dartmouth College is developing a new wireless sensor edge network for Internet based on the concept of people-centric sensing at scale. We are studying three aspects of the problem: (i) the large-scale deployment of mobile people-centric sensors (both motes and sensor-enabled cell phones) and their interaction with embedded static sensor webs; (ii) the concept of opportunistic tasking, sensing, and collection; and (iii) security, trust, and privacy - because people-centric sensing raises a number of important privacy issues. In this talk, I will discuss our progress in designing and implementing MetroSense and a number applications drivers (i.e., BikeNet - for cyclist experience mapping, CenceMe - for Injecting sensing presence into social networking applications, and PASS - considering people-as-sensors).

Andrew received his PhD in Computer Science (1996) from Lancaster University, England, and the NSF Career Award (1999) for his research in programmable wireless networking. Prior to joining academia he spent 10 years working in industry both in Europe and the USA in product research and development of computer networks and wireless packet networks. Andrew has been been a technical program chair for ACM MobiCom and ACM MobiHoc, and the general chair for ACM SenSys 2006. He spent his sabbatical year (2003-2004) at the Computer Lab, Cambridge University, as an EPSRC Visiting Fellow.
