Participatory Sensing: Opportunities and Challenges
Many critical issues facing science, government, business and the public call for high fidelity and relevant time understanding of physical phenomena. Participatory Sensing in which individuals and communities leverage always on and carried mobile devices to systematically capture and analyze data, complements the Internet of information and things by supporting increased visibility into the determinants and impacts of our daily actions and choices. Innovative data practices (from measurement, to analysis and sharing) can reveal the previously unobservable about us and our environments, and in so doing help us understand and manage our interactions with the physical world, with ourselves, and with one another. One of the most active application areas for Participatory Sensing (PS) is health and wellness. Participatory mobile health (mHealth) incorporates a variety of techniques, including automated actigraphy and mobility traces, smart context based reminders, phone-mediated exercises, and prompted experience sampling inputs. mHealth can assist individuals with adherence to their treatment regimen during the course of their everyday activities, while providing to clinicians and researchers information about daily patterns that were not previously practical but that are critical to personalized diagnosis and treatment.
This talk will discuss the broad opportunities for social innovation and the many challenges for technical development. I will draw upon our experience to date with PS and mHealth pilots and prototypes and will address technical areas in need of significant R&D: open modular tools for data analysis and visualization across diverse data types and data consumers, engagement such as adaptive goal setting and game mechanics, and privacy mechanisms such as Personal Data Vaults and selective sharing.
Deborah Estrin is a Professor of Computer Science, holds the Jon Postel Chair in Computer Networks, and is Founding Director of the NSF-funded Center for Embedded Networked Sensing (CENS). She received her Ph.D. (1985) in Computer Science from M.I.T., and her B.S. (1980) from U.C. Berkeley. Estrin’s early research focused on the design of network protocols, including multicast and inter-domain routing. In 2002 Estrin founded the NSF-funded Center for Embedded Networked Sensing (http://cens.ucla.edu) to develop and explore environmental monitoring technologies and applications. Most recently Estrin and collaborators are developing and deploying participatory sensing systems, leveraging the location, image, and user-contributed data streams increasingly available globally from mobile phones. Ongoing projects include self-monitoring applications in support of health and wellness (http://openmhealth.org), citizen science (http://whatsinvasive.com), and STEM education (http://mobilizingcs.org). Professor Estrin is an elected member of the American Academy of Arts and Sciences (2007) and the National Academy of Engineering (2009). She is a fellow of the IEEE, ACM, and AAAS. She was selected as the first ACM-W Athena Lecturer in 2006, awarded the Anita Borg Institute's Women of Vision Award for Innovation in 2007, inducted into the WITI hall of fame in 2008, and awarded Doctor Honoris Causa from EPFL (2008) and from Uppsala University (2011).

Secure and Efficient Networking in the TV Band White Spaces Highlights from the Microsoft Research White Space Project
The FCC's recent decision to open up the "White Spaces" in UHF TV band spectrum for unlicensed use is historic and has created tremendous interest in industry and research. It signifies a fundamental paradigm shift, as for the first time, wireless devices are allowed to opportunistically use licensed spectrum as long as they do not cause interference with any incumbent. In this talk, I will give an overview of the Microsoft Research White Space project. In this project, we have developed a series of technologies that ultimately allowed us to deploy the world's first wireless network operating over white spaces. The network provides Internet access by efficiently and opportunistically "reusing" unoccupied parts of the TV band spectrum. It enables new application scenarios, and has been instrumental in the FCC's regulatory decisions. The main technical focus of my talk will be on new solutions to a key challenge in white space networks: How to securely protect primary users from harmful interference, while still giving white space devices as much access to the spectrum as possible. I will discuss two new techniques that collectively yield an efficient solution to this coexistence problem, as well as their implications on the underlying network protocols.
Thomas Moscibroda is a Lead Researcher at Microsoft Research Asia in Beijing. He is also an Adjunct Professor at the Institute of Interdisciplinary Information Sciences (IIIS) at Tsinghua University. Before moving to China in 2011, he was a member of the Distributed Systems Research group at Microsoft Research in Redmond for 5 years, as well as an affiliate member of the Networking Research Group and the Computer Architecture Research group at MSR Redmond, respectively. Thomas obtained his MS in 2004, and his PhD in 2006 both from ETH Zurich, and was awarded the ETH Medal for his doctoral thesis. His research interests are in distributed algorithms, (wireless) networking, and computer architecture, with ongoing projects in each of these areas. He has a particular focus on algorithmic and mathematical approaches to practical system problems.
Thomas' research is documented in more than 50 research papers, and he has received Best Paper Awards at several highly-prestigious conferences, including PODC 2004, IPSN 2007, SIGCOMM 2009, NSDI 2009, and ASPLOS 2010. In addition, he is the recipient of Best Presentation Awards from MOBICOM 2004 and PODC 2008, and his articles on DRAM scheduling and on-chip networking in multi-core systems were selected as IEEE Micro Top-Pick Computer Architecture papers in 2008 and 2010, respectively. Thomas is also the inventor of more than 35 patents, several of which have been filed internationally.
Among other projects, Thomas has been co-leading Microsoft's initiative on White Space networking, building the world's first operational White Space network. Spectrum regulators from India, China, Brazil, Singapore, and the US (including the FCC Chairman) have visited the Microsoft Campus in Redmond to see a live demonstration of his research. This work has been instrumental in the recent historic spectrum policy decisions taken by various governments (USA, UK, ...) to open up TV band spectrum for unlicensed use.

Rethinking Security for A World of Networked Devices
As the numbers of devices per person and per organization grow dramatically, the challenges associated with the manageability of the associated security material become daunting. The conventional approach of using public or symmetric keys, which are updated from time to time or from session to session, is therefore ripe for being reconsidered. In this talk, we will present extremal alternatives wherein keys are either eschewed, based on exploitation of the physical layer, or keys are used without the need for updates. We will explore the use of such keys in providing diverse sorts of end-to-end security properties in device networks and discuss the consequences of device compromise in the model. Our discussion will include a survey of the state-of-the-art and the feasibility of our methods, including current experimental results.

Anish has led research and development of diverse wireless sensor network applications: a large-scale persistent perimeter surveillance ExScal Project (for extreme scale); a multi-platform, multi-environment, KanseiGenie fabric for application development, testing, and deployment, which has now been integrated into and variously cloned in the NSF GENI next generation internet prototype; a "mote"-augmented-cellphone and building array fabric for hosting people-centric and smart grid applications called PeopleNet; and the BumbleBee/GuardBee micropower radar systems for people activity sensing. Recent system platforms work includes a state-of-the-art wireless sensor mote, the eMote, which runs the .NET micro framework in an energy efficient manner. More broadly, his research focuses on the end-to-end fault-tolerance, security, and timeliness of distributed systems and networks and has yielded a number of innovations in scalable dependability.
