Real-Time Middleware for Networked Embedded Systems
General purpose middleware such as CORBA has been shown to be effective off-the-shelf, in meeting diverse functional requirements for a wide range of distributed systems. However, middleware customization is necessary for many networked embedded systems because of the resource constraints in the networked nodes. In this project, we demonstrate that reduced middleware footprint can be achieved while maintaining real-time properties of applications running on such systems. We also give evidence that empirical measurement using a representative application is crucial to guide (1) selection of feature subsets from general purpose middleware and (2) trade-offs among different dimensions of design metrics including real-time, footprint, and portability.
