Abstract

This paper summarizes a survey of the published research in real-time systems. Material is presented which provides an overview of the topic focusing on communications protocols and scheduling techniques. It is noted that real-time systems deserve special attention separate from other areas because of their unique properties. In computer science and operations research this has not been the case until quite recently resulting in the absence of formal tools for design and analysis of real-time systems. Summaries are given beginning with early work on applications as well as notable theoretical advances. This is followed by descriptions of more recent work in the field from the mid-1980's to the present.
