Abstract:
Running congestion control at the transport layer has been one of the key
enabling factors of the Internet. Today, the same congestion control
represents one of the major problems for the integration of impaired
networks, i.e., network segments characterized by high bit error rates and
delays, such as wireless and satellite networks, in the Internet. In fact,
high bit error rates may cause packet losses that are misinterpreted by
congestion control protocols as the evidence of a congestion and therefore,
result in unnecessary transmission rate decrease. This problem is further
amplified if the bandwidth-delay product is high. In the recent past a
large research effort has been devoted to solve the above issues and
several solutions have been proposed.
In this talk we will describe a complete transport layer protocol suite
optimized for wireless and satellite communications. Indeed, we will
consider both end-to-end solutions as well as proxy-based solutions
highlighting pros and cons of each of them. Some of the solutions covered
by the talk are TCP-Peach, PETRA, and rate control scheme (RCS), that we
have proposed in the recent past. Furthermore, we will highlight the most
challenging open research issues in the specific research context.
Biography:
Dr. Giacomo Morabito received the laurea degree in Electronic Engineering
and the PhD in Electronic, Computer, and Communications Engineering from
the University of Catania (Italy) in 1996 and 1999, respectively. From 1999
to 2001 he has worked as research engineer at the Broadband and Wireless
Networking Laboratory of the Georgia Institute of Technology, Atlanta GA.
In 2001 he has joined the Departiment of Computer and Communication
Engineering of the University of Catania where he is currently associate
professor. His research interests focus on modeling and analysis of
broadband networks as well as energy efficient protocols for wireless
networks. More info can be found at:
