Reasoning for Smart Space Application: Comparing Three Reasoning Engines CLIPS, Jess and Win-prolog

This article presents Collect&Drop application, a pervasive system which utilizes RFID technology to store and pick digital content with mobile phones and play it with smart space’s displays and speakers. Collect&Drop is implemented with the support of three reasoning engines, based on CLIPS, Jess and Win-Prolog. We discuss advantages and drawbacks of integrating a reasoning engine into the system, both qualitatively and quantitatively. Also comparison of the three engines implementations is made with respect to performance and resource consumption.
