The rapid growth of information technology and the Internet give rise to an increasing demand for information services. A large number of service providers offer information services to diversified users on the Internet. Users' requirements are heterogeneous and change very quickly. Popular servers are overloaded and cannot dynamically adapt to meet users' heterogeneous requirements. It is necessary to design an information service system that can meet users' heterogeneous requirements for services, and adaptability of services to cope with ever-changing situations to provide assurance. Faded information field architecture and Push/Pull mobile agent technologies have been proposed as basic components of an autonomous information service system to achieve these goals. The system has been proposed from users' and providers' points of view, and therefore techniques, for balancing users' and providers' costs are required for realization of the system. The system leads toward dynamic and autonomous information allocation, in which each node on the network may determine information amount based on push/pull cost of mobile agents. In this paper, we propose initial construction of faded information field based on providers' and users' heterogeneous reliability requirements. Through rate is used to reconstruct faded information field, dynamically and autonomously. We prove the effectiveness of the proposed technology through simulation.
