MobiArch 2006 Keynote Speeches

Keynote 1:  Charles Perkins (Nokia Research Center, Palo Alto, CA, USA)
   Ad Hoc Networks, IETF, and Convergence in Solution Space (Slides)

Abstract:

Within the IETF, the working group for Mobile Ad Hoc Networking (MANET) has recently made new steps towards standardizing new routing protocols.  In particular, there is now a document specifying a new protocol called DYMO (for Dynamic Mobile Networks).  

I will discuss these recent steps forward, and to give concrete examples I will describe more specifically some recent improvements to "Ad Hoc On-Demand Distance Vector" protocol (AODV) [RFC 3561].  Four protocols have been published as experimental specifications within the MANET working group of the IETF.  I will describe in brief certain aspects of these protocols, and then go into a more detailed description of DYMO.  After describing these protocols, I will then give some opinions about how a convergence may be affected.  Convergence between protocols does provide a significant force for acceptance, and so technology that finds commonality between otherwise divergent protocols is highly desirable. The good and recent news is that commonality has been identified, so that link-state and distance-vector protocols can be merged, as well as (possibly!) proactive and reactive protocols.  Along the way, much has been learned about the basic nature of routing protocols, and yet much remains to be learned. I will present some interesting recent performance results and suggest some avenues for further research results.

Keynote Speaker's Short Biography:

Charles E. Perkins is a Nokia Fellow at the Palo Alto Systems Research Center within Nokia Research Center, investigating mobile wireless networking and dynamic configuration protocols. He is serving as document editor for the mobile-IP working group of the Internet Engineering Task Force (IETF), and is author or co-author of standards-track documents in the mip4, mip6, manet, dhc, seamoby (Seamless Mobility) and autoconf working groups.  He is an editor for several ACM and IEEE journals for areas related to wireless networking.  While at Nokia, he has continued strong involvement with research activities for ad hoc networking and scalability and performance issues related to Internet access for billions of portable wireless devices.

Charles has authored and edited books on Mobile IP and Ad Hoc Networking, and has published a number of papers and award winning articles in the areas of mobile networking, ad-hoc networking, route optimization for mobile networking, resource discovery, and automatic configuration for mobile computers.  Charles was also one of the creators of MobiHoc, the premier conference series that has provided the forum for many of the most important publications in the field of ad hoc networking; he remains on the steering committee for that conference.  He has served as general chair and Program Committee chair for MobiHoc, and has just completed service as general co-chair of MASS 2006.  Charles has served on the Internet Architecture Board (IAB) of the IETF and on various committees for the National Research Council, as well as numerous technical assessment boards for Army Research Lab and the Swiss MICS program.  He has also served as associate editor for Mobile Communications and Computing Review, the official publication of ACM SIGMOBILE, and has served on the editorial staff for IEEE Internet Computing magazine. 

Keynote 2:  Henning Schulzrinne (Columbia University, New York, NY, USA)
  User Mobility in IEEE 802.11 Networks (Slides)
 

Abstract  

We observed wireless network traffic at the 65th IETF Meeting in Dallas, Texas in March of 2006, attended by approximately 1200 engineers. We observed distinct differences among client implementations and saw a number of factors that made the overall system less than optimal, pointing to the need for better design tools and automated adaptation mechanisms.

In order to solve many of the problems encountered in the IETF measurements and many other issues such as Layer 2 (L2) and Layer 3 (L3) handoffs, critical for real-time applications, we propose a novel approach, namely Cooperative Roaming (CR), in which mobile nodes (MNs) can collaborate with each other and share useful information about the network in which they move.

Keynote Speaker's Short Biography:

Prof.  Henning Schulzrinne received his undergraduate degree in economics and electrical engineering from the Darmstadt University of Technology, Germany, his MSEE degree as a Fulbright scholar from the University of Cincinnati, Ohio and his Ph.D. degree from the University of Massachusetts in Amherst, Massachusetts.  He was a member of technical staff at AT&T Bell Laboratories, Murray Hill and an associate department head at GMD-Fokus (Berlin), before joining the Computer Science and Electrical Engineering departments at Columbia University, New York.  He is currently chair of the Department of Computer Science. 

He is editor of the "IEEE/ACM Transactions on Networking", the "ACM Transactions on Multimedia Computing" and the "ComSoc Surveys & Tutorials" and former editor of the "IEEE Internet Computing Magazine", "IEEE Transactions on Image Processing" and "Journal of Communications and Networks",

He has been a member of the Board of Governors of the IEEE Communications Society and the ACM SIGCOMM Executive Committee, former chair of the IEEE Communications Society Technical Committees on Computer Communications and the Internet and has been technical program chair of Global Internet, Infocom, NOSSDAV and IPtel and was General Chair of ACM Multimedia 2004.  He also was a member of the IAB (Internet Architecture Board).

Protocols co-developed by him are now Internet standards, used by almost all Internet telephony and multimedia applications. His research interests include Internet multimedia systems, quality of service, and performance evaluation.

He serves as Chief Scientist for FirstHand Technologies.  and as former Chief Scientific Advisor for Ubiquity Software Corporation.  He is a Fellow of the IEEE, has received the New York City Mayor's Award for Excellence in Science and Technology, the VON Pioneer Award.
