Push and pull of information in autonomous information service system

The Internet is a heterogeneous and rapidly evolving environment. New information services have been added, modified and diversified, while legacy services have been abandoned. Users´ requirements for services are changing very quickly. It is becoming very difficult to find the required information services in the Internet from the extremely huge amount of information. It is necessary to design an information service system which can meet user´s heterogeneous requirements for services, adaptability of services to cope with ever-changing situations and to reduce access time for the users. Faded information field architecture and push/pull mobile agent technologies have been proposed to achieve these goals. Push-MA for the service provider allocates information into distributed nodes to create a faded information field. Pull-MA autonomously searches appropriate information in these distributed nodes for a user. We propose a technique for balancing SP and the user´s point of view for faded information field construction. The purpose is to minimize total traffic due to push and pull of information for a given user´s demand distribution
