Abstract
Mobile agents are programs that can move and work on computers in computer networks without any program pre-installation. At present, mobile agents are employed by various networked applications. An application domain which is believed to be suitable for agent deployment is distributed database. In this paper, we use mobile agents for distributed database statistic collection. The collected database statistics will be used by the cost-based query optimizer of each site to determine the best physical access plan for a given database query. Statistics collection even though useful is time consuming and could slow down other database operations. Mobile agents are employed to find suitable time for statistic collection in order to reduce the interference.
