Middleware Architectures for Distributed Embedded Systems

A wide range of high-performance distributed embedded systems have been designed and deployed. Physically distributed embedded systems are used for manufacturing and control, traffic analysis, and other problems. Interestingly, today's systems-on-chips are sufficiently complex that they must be treated as distributed embedded systems. At all scales of physical extent, middleware is required to manage the computations. This paper looks at distributed embedded systems at several physical scales and considers the types of middleware that are needed to operate these systems.
