Enhancement of DeLC for the provision of intelligent mobile services

This paper presents new enhanced version of Distributed eLearning Center (DeLC), providing intelligent mobile services for users in a university campus. The main enhancements are related to the extension of DeLC network model to a 3-tier structure and introduction of new intelligent elements into it. A re-engineering approach for the realization of required changes in DeLC system architecture is proposed, which allows re-use of services already deployed in the existing version of DeLC and development of new mobile services based on intelligent agents used as personal helpers for DeLC users. A description of some of the mobile services along with supporting communication infrastructure is also provided.
