Title: Is There Any Practical Theory?


With students and collaborators, I have extensively studied sensor networks, both theory and practice. Despite all our efforts, I did not really manage to marry theory and practice. It was always rather theory or practice. In my talk I will present a few hopefully exciting case studies in search for efficient and reliable sensor networks: What is the right data gathering protocol? How about an alarming system, and wireless network communication in general? Would the capture effect help? Can we guarantee to never forget an event?

Bio of the speaker

Roger Wattenhofer is a full professor at the Information Technology and Electrical Engineering Department, ETH Zurich, Switzerland. He received his doctorate in Computer Science in 1998 from ETH Zurich. From 1999 to 2001 he was in the USA, first at Brown University in Providence, RI, then at Microsoft Research in Redmond, WA. He then returned to ETH Zurich, originally as an assistant professor at the Computer Science Department.

Roger Wattenhofer's research interests are a variety of algorithmic and systems aspects in computer science and information technology, e.g., distributed systems, positioning systems, wireless networks, mobile systems, social networks. He publishes in different communities: distributed computing (e.g., PODC, SPAA, DISC), networking (e.g., SIGCOMM, MobiCom, SenSys), or theory (e.g., STOC, FOCS, SODA, ICALP). He recently published the book "Distributed Ledger Technology: The Science of the Blockchain".
