Towards universal software substrate for distributed embedded systems

The paper proposes a universal software substrate for building various types of distributed embedded systems. The universal software substrate contains an operating system and several middleware components. It offers a universal application programming interface (Universal API) that greatly increases an embedded application's portability. Also, it makes the development speed of distributed embedded applications dramatically fast, since the high level abstraction provided by universal software substrate decreases the amount of software that should be written from scratch. The most important issue of our research is how to control the level of abstraction when designing distributed embedded systems. Our work is looking for methodologies to build portable software for distributed embedded systems in a systematic way. We describe several software components towards realizing universal software substrate, and some research topics for achieving the goals
