Apr 26, 2007: On Quality-of-Service of Networked Embedded Systems
Filed in: Colloquium
Prof. Kang Shin, Kevin and Nancy O'Connor Professor
of Computer Science, University of Michigan
There has been an exponential growth of applications that rely on diverse types of embedded end-systems and devices, such as cell phones, handheld entertainment devices, home appliances, consumer and industrial electronics, smart sensors and actuators. These applications require (1) end-systems to be networked together via heterogeneous networking technologies and procotols, and (2) diverse types of end-to-end Quality-of-Service (QoS) including timeliness, dependability, security and privacy.
We now know how to guarantee timeliness and, to a lesser extent, how to provide fault-tolerance, on both end-systems and their interconnection networks. However, how to secure them is far lesser known, despite the growing importance of protecting information stored in the end systems/devices and exchanged over their interconnection networks. Morever, timeliness, fault-tolerance, security and privacy---which I simply call QoS---must be supported simultaneously, often with a tight resource budget such as memory, computation and communication bandwidth, and electric power. Also, different applications require different combinations of QoS components, and hence, one-fits-all solutions are not acceptable. This talk will cover issues and approaches to the problems of building QoS-sensitive networked embedded systems.
Kang G. Shin is the Kevin and Nancy O'Connor Professor of Computer Science and Founding Director of the Real-Time Computing Laboratory in the Department of Electrical Engineering and Computer Science, The University of Michigan, Ann Arbor, Michigan. His current research focuses on QoS-sensitive networking and computing as well as on embedded real-time OS, middleware and applications. He has supervised the completion of 56 PhD theses, and authored/coauthored more than 650 technical papers and numerous book chapters in the areas of distributed real-time computing and control, computer networking, fault-tolerant computing, and intelligent manufacturing.

Abstract
There has been an exponential growth of applications that rely on diverse types of embedded end-systems and devices, such as cell phones, handheld entertainment devices, home appliances, consumer and industrial electronics, smart sensors and actuators. These applications require (1) end-systems to be networked together via heterogeneous networking technologies and procotols, and (2) diverse types of end-to-end Quality-of-Service (QoS) including timeliness, dependability, security and privacy.
We now know how to guarantee timeliness and, to a lesser extent, how to provide fault-tolerance, on both end-systems and their interconnection networks. However, how to secure them is far lesser known, despite the growing importance of protecting information stored in the end systems/devices and exchanged over their interconnection networks. Morever, timeliness, fault-tolerance, security and privacy---which I simply call QoS---must be supported simultaneously, often with a tight resource budget such as memory, computation and communication bandwidth, and electric power. Also, different applications require different combinations of QoS components, and hence, one-fits-all solutions are not acceptable. This talk will cover issues and approaches to the problems of building QoS-sensitive networked embedded systems.
