Autonomous navigation architecture for load balancing user demands in distributed information systems

Autonomous Information Service System is a proposition made to cope with th e continuously changing conditions of service provision and utilization in current information systems. The faded information field (FIF), sustained b y push/pull mobile agent technology, is such a distributed architecture tha t brings high-assurance of the system through a balanced selective replicat ion of the information. When the demand changes, the information environmen t is restructured so that the same response time to services for all unspec ified users can be achieved whatever the demand volume. However, once the s tructure is fixed, dispatching the randomly incoming requests on the FIF is still required to guarantee the same quality of service. Our goal is to wa rrant the autonomous dispatching of the pull mobile agents to adjust the co ntinuously evolving arrival distribution of the demand to the current infor mation environment. In this paper, we explain the concepts and realization of autonomous navigation under the goal of an autonomous load balancing of the pull mobile agent volume in the FIF structure. The appropriateness of t his method for FIF environments has been shown by simulation.
