Autonomous node reallocation for achieving load balance under changing users' preference

Abstract

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 user's access, it can be said that popularity of information utilization generally exists in information system. This paper introduces an access-based rating oriented distributed information system sustained by push/pull mobile agents for information service provision and utilization. In this environment, autonomous node adjustment technology is proposed to achieve load balance in the situation of changing users' preference. The effectiveness of our proposed technology is proved by simulation.
