Future Directions and Perspectives on Wireless Sensor Networks

Dr. Sajal K. Das

Program Director, National Science Foundation
Director, Center for Research in Wireless Mobility and Networking (CReWMaN)
The University of Texas at Arlington

Rapid advancements in embedded systems, sensors and wireless communication technologies have led to the development of cyber-physical systems, pervasive computing and smart environments with important applications in civilian, military, industry, and government sectors. Wireless sensor networks (WSNs) play a significant role in such systems as they can effectively act as the human-physical world interface with the digital world through sensing and actuation. However, the inherent characteristics of WSNs typified by extremely scarce resources (bandwidth, CPU, memory and battery power), high degree of uncertainty, distributed control and operations pose significant challenges in providing the desired information quality, assurance, and reliability for information fusion and intelligent decision making. This is particularly important for such critical applications as smart grids, smart health care or pervasive security, to name a few.

This talk will examine uncertainty-driven unique research challenges in cyber-physical and networked sensor systems, and propose some novel solutions for data aggregation/fusion, dissemination, routing, coverage and connectivity, security and privacy with improved quality in information-intensive (e.g., multimedia) wireless sensor networks. The talk will be concluded with open issues and future directions of research.

About the Speaker: Dr. Sajal K. Das is a University Distinguished Scholar Professor of Computer Science and Engineering and the Founding Director of the Center for Research in Wireless Mobility and Networking (CReWMaN) at the University of Texas at Arlington (UTA). He is currently a Program Director at the National Science Foundation in the Division of Computer Networks and Systems (CISE/CNS). He is also a Visiting Professor at IIT- Kanpur, India and a Concurrent Professor of Fudan University in Shanghai, China. His current research interests include wireless and sensor networks, mobile and pervasive computing, smart environments, security and privacy, cloud computing, social networks, biological networking, applied graph theory and game theory. He has published over 400 papers and over 35 invited book chapters, and holds five US patents in wireless networks and mobile Internet. Dr. Das coauthored two books - Smart Environments: Technology, Protocols, and Applications (Wiley, 2005) and Mobile Agents in Distributed Computing and Networking (Wiley, 2010). He is a recipient of the IEEE Computer Society Technical Achievement Award (2009) for pioneering contributions to sensor networks and mobile computing; IEEE Region 5 Outstanding Engineering Educator Award (2008); and several Best Paper Awards in such conferences as EWSN'08, IEEE PerCom'06, and ACM MobiCom'99.

Network Neutrality — Why it's Important and What it Means for Network Engineers

Barbara van Schewick

Director, Center for Internet and Society
Stanford Law School

The debate over "network neutrality," i.e. the debate over whether governments should establish rules limiting the extent to which network providers can interfere with the applications and content on their networks, has become one of the hottest debates in Internet policy. Governments all over the world, including the European Union, the UK, France, Germany and the US, are investigating whether regulatory action is needed. The outcome of the debate will not only shape the future of the Internet; for network engineers, network neutrality rules may also influence which technical solutions to networking problems they can develop in the future. At the same time, the debate has evolved into a series of sub-debates that are difficult to follow, making it difficult for interested observers to understand what the various proposals may mean for them.

This talk will discuss the different questions that regulators are currently considering and will explain how the different proposals for answering them will affect network engineers as users and developers of Internet technology.

About the Speaker: Barbara van Schewick is an Associate Professor of Law at Stanford Law School, an Associate Professor (by courtesy) of Electrical Engineering at Stanford's Department of Electrical Engineering, and the Director of Stanford Law School's Center for Internet and Society. Her book Internet Architecture and Innovation was published by MIT Press in July 2010.

Van Schewick's research focuses on the economic, regulatory, and strategic implications of communication networks. In particular, she explores how changes in the architecture of computer networks affect the economic environment for innovation and competition on the Internet, and how the law should react to these changes. This work has made her a leading expert on the issue of network neutrality, perhaps the Internet's most debated policy issue, which concerns Internet users' ability to access the content and software of their choice without interference from network providers. Her papers on network neutrality have influenced regulatory debates in the United States, Canada and Europe.

In 2007, van Schewick was one of three academics who, together with public interest groups, filed the petition that started the US Federal Communications Commission's network neutrality inquiry into Comcast's blocking of BitTorrent and other peer-to-peer protocols. She has testified before the FCC in en banc hearings and official workshops. She co-authored an amicus brief — along with Professors Jack Balkin, Lawrence Lessig, and Tim Wu, among others — defending the FCC order that ordered Comcast to stop interfering with BitTorrent.

Prior to joining the Stanford Law faculty, van Schewick was a senior researcher at the Technical University Berlin, and a nonresidential fellow of Stanford Law School's Center for Internet and Society. From August 2000 to November 2001, she was that Center's first residential fellow.
