A publication-subscription interaction schema for desktop grid computing

Abstract

This paper proposes a Publish-Subscribe framework for the design of Desktop Grid (DG) middleware. This work focuses on a modeling and a verification of a DG protocol based on the Publish-Subscribe paradigm and introduces a prototype that we are currently developing. Our prototype implementation is based on Redis, a key-value no-SQL Web 2.0 tool with Publish-Subscribe functionality. Whereas most previous approaches required to build a number of layers before the layer of the DG middleware, we have only one layer in our system. In addition, our system is characterized to be light in terms of coding lines and used resources. It is therefore very convenient to implement DGs on resource constrained systems, e.g. tablets and smartphones.
