Emerging Trends in Adaptive Middleware and Its Application to Distributed Real-Time Embedded Systems

摘要

Embedded systems have become prevalent in today's computing world and more and more of these embedded systems are highly distributed and network centric. This adds increasing degrees of resource contention, unpredictability, and dynamism to software that has traditionally been designed with resources being provisioned statically and for the worst case. This paper describes the research that we've been doing in the development of middleware for QoS adaptive systems - an extension to standard off-the-shelf distributed object middleware - and its application to two military distributed real-time embedded systems. These real-world evaluations of the technology then motivate a discussion of the next directions in which we are taking this research.
