Autonomous information fading by mobile agents for improving user´s access time and fault tolerance

Information Services on the Internet have been rapidly changing. New information services have been added, modified, and diversified, while legacy services have been abandoned. Users´ requirements for the services have been changed day-by-day and person-by-person. It is becoming very difficult to find required information services in the Internet with extremely huge information base, especially for novice users. It is necessary to design information service system, which can meet customer´s heterogeneous requirements for services, adaptability of services to cope with ever-changing situation and to reduce access time for the users. Faded information field system architecture and Push-MA (Mobile Agent)/Pull-MA technologies have been proposed to achieve these goals. Push-MA for service provider allocates information into distributed nodes to create faded information field. Pull-MA autonomously searches for appropriate information from these distributed nodes for a user. In this paper, we discuss how and under what conditions faded information field is created by Push-MA
