Autonomous navigation in information service systems for load balancing user demands

Abstract

Autonomous information service system is a proposition made to cope with the continuously changing conditions of service provision and utilization in current information systems. The faded information field (FIF), sustained by Push/Pull mobile agent technology, is such a distributed architecture that brings high-assurance of the system through a balanced selective replication of the information. When the demand changes, the information environment is restructured so that the same access time to services for all unspecified users can be achieved in the system. However once the structure is fixed, balancing the incoming demand on the FIF is still required to guarantee the equal access time. Our goal is to warrant the autonomous dispatching of the Pull mobile agents to adjust the demand to the current information environment. We explain the concepts and realization of autonomous navigation under the goal of asynchronous load balancing of the pull mobile agent volume inside the FIF structure. The effectiveness of our algorithm has been confirmed by simulation.
