Agent-based rating oriented information provision and for high-assurance in open and dynamic environments

In order to meet the heterogeneous requirements from service providers and users simultaneously, there is an urgent need for a new information service system. After studying the characteristics of the users´ accessing, that popularity of information utilization generally exists in information system is focused. This paper introduces a rating oriented distributed information system sustained by push/pull mobile agents for information service provision and utilization. Based on this environment, autonomous information allocation technology is proposed. However, when users´ demand changes, congestion might arise in the system. In order to achieve load balance for users´ timeliness access and guarantee that users can always get the information from a certain pathway, autonomous information reallocation technology is proposed. Through the comparison simulation to the conventional system, the effectiveness of proposed system is proved.
