TCP Boston: a fragmentation-tolerant TCP protocol for ATM networks
We propose a new transport protocol, TCP Boston, that turns the ATM's 53-byte cell-oriented switching architecture into an advantage for TCP/IP. At the core of TCP Boston is the adaptive information dispersal algorithm (AIDA), an efficient encoding technique that allows for dynamic redundancy control. AIDA makes the TCP/IP's performance less sensitive to cell losses, thus ensuring a graceful degradation of the TCP/IP's performance when faced with congested resources. We introduce AIDA and overview the main features of TCP Boston. We present detailed simulation results that show the superiority of our protocol when compared to other adaptations of TCP/IP over ATMs.

Exploiting redundancy for timeliness in TCP Boston
In a recently completed study, we have unveiled a new transport protocol, TCP Boston, that turns ATM's 53-byte cell-oriented switching architecture into an advantage for TCP/IP. In this paper, we demonstrate the real-time features of TCP Boston that allow communication bandwidth to be traded off for timeliness. We stall with an overview of the protocol, and analytically characterize the dynamic redundancy control features of TCP Boston. Next, we present detailed simulation results that show the superiority TCP Boston compared to other adaptations of TCP/IP over ATMs. Namely, we show that it improves TCP/IP's performance over ATMs for both network-centric metrics (e.g., throughput and percent of missed deadlines) and real-time application-centric metrics (e.g., response time and jitter).

Tripodal schematic design of the control architecture for the Service Robot PSR
This paper describes a control architecture design and a system integration strategy for the autonomous service robot PSR (Public Service Robot). The PSR is under development at the KIST (Korea Institute of Science and Technology) for service tasks in public spaces such as office buildings and hospitals. The proposed control architecture is designed by tripodal frameworks, which are layered functionality diagram, class diagram, and configuration diagram. The tripodal schematic design clearly points out the way of integrating various hardware and software components. The developed strategy is implemented on the PSR and successfully tested.
