Introduction to the Special Issue:

The Work-in-Progress Session of the 2005 IEEE Real-Time and Embedded Technology and Applications Symposium brings together some of the latest on-going projects in real-time and embedded systems. Ten papers have been selected to appear in this session and are presented in this issue. There are at least two reviews from the program committee for each paper, and in many cases there are three or four reviews. Papers coauthored by me, my students, and collaborators were handled by Real-Time Infrastructure Track Program Chair Oleg Sokolsky.

The WiP Session has been divided into four mini-sessions, covering four major areas of real-time systems research: (1) power-aware systems, (2) scheduling, (3) analysis and verification, and (4) system software and hardware. This issue also follows this format and has grouped the papers into these four areas. The first two papers (Wang and Cheng, Kumar and G. Manimaran) describe new strategies to conserve energy in real-time and embedded systems. Then the following three papers (Chen and Cheng, Qadi and Goddard, Johnstone and Bradley) present novel scheduling strategies and applications. The next three papers (Nguyen et al, Oehlerking et al, Sundmark et al) deal with the verification and testing of embedded systems. The final two papers (Chousein and Mahapatra, Fryer) look at hardware-based approaches for real-time and embedded applications. I hope that you will find this issue stimulating and rewarding.
