Abstract

General purpose middleware has been shown to be effectiveoff-the-shelf, in meeting diverse functional requirementsfor a wide range of distributed systems. However,middleware customization is necessary for many networkedembedded systems because of the resource constraints inthe networked nodes. In this paper, we demonstrate thatreduced middleware footprint can be achieved while maintainingreal-time properties of applications running on suchsystems. We also give evidence that empirical measurementusing a representative application is crucial to guide (1)selection of feature subsets from general purpose middlewareand (2) trade-offs among different dimensions of designmetrics including real-time, footprint, and portability.
