DTC Seminar Series

Bringing Location Awareness From Applications to Protocols

Accessing information at any time, any place has been a key driver for 3G services. Mobile operators have hedged their investments on 3G adoption for some time. However, there are indications that several new standards in the unlicensed spectrum, e.g. Bluetooth, are set to provide an alternative, more cost-effective, solution for mobile Internet connectivity, based on ad-hoc network architectures. By combining the cost advantages of these technologies with the application context (e.g. location, time, activity, previous history), the emerging sentient computers hold a significant promise for a seamless use of tomorrow's wireless networks in which mobile computing and Internet connectivity will be provided for professional and recreational activities through PDAs, smart phones, laptops, and other mobile appliances. This talk outlines some of the challenges encountered in building protocol solutions for these networks which have random and unpredictably changing topology, and can be expected to be very large. In particular we show that by incorporating the same context information in designing the ad-hoc network protocols, it is possible to construct robust routing solutions, that can deal with some of the main challenges of these networks, timeliness, bandwidth efficiency and scalability.


Imrich Chlamtac holds a Ph.D degree in computer science from the University of Minnesota. Since 1997 he is the Distinguished Chair in Telecommunications at the University of Texas at Dallas. Dr. Chlamtac also holds the titles of the Sackler Professor at Tel Aviv University, Israel, The Bruno Kessler Honorary Professor at the University of Trento, Italy, and of University Professor at the Technical University of Budapest, Hungary. Dr. Chlamtac is a Fellow of the IEEE and ACM societies, a Fulbright Scholar and an IEEE Distinguished Lecturer. He is the winner of the 2001 ACM award for contributions to wireless and mobile networks. In 2002 he received the IEEE TCPC Annual Award for contributions to wireless networking. Dr. Chlamtac published close to 300 papers in refereed journals and conferences, with multiple best paper awards. He is the co-author of the first textbook on Local Area Networks (Lexington Books, 1981, 1982, 1984) and of Mobile and Wireless Networks Protocols and Services (John Wiley & Sons, Pub.,2000), an IEEE Network Magazine's 2000 Editor's Choice. Dr. Chlamtac serves as the founding Editor in Chief of the ACM/URSI/Kluwer Wireless Networks (WINET), the ACM/Kluwer Mobile Networks and Applications (MONET) Journals and the SPIE/Kluwer Optical Networks (ONM) Magazine. He is also the founder and Steering Committee Chair of ACM/IEEE MobiCom and SPIE/IEEE/ACM OptiComm conferences.
