Abstract

The turn of the century is witnessing radical changes in the way information services are spreading due to the progress of IT and the constantly increase in the number of users of the WWW. Therefore, the business market is changing its strategy for a modern online business environment. Autonomous Decentralized Database System (ADDS), based on autonomous coordinating subsystems, has been proposed as a system architecture in order to meet the innovative e-business requirements for consistency and high response among distributed database systems. Autonomy and decentralization of subsystems help achieving high response time in highly competitive situation and autonomous Mobile Agent based coordination has been proposed to achieve flexibility in a highly dynamic environment. In this paper, it is analyzed the case in which the system size increases; and a multi agent coordination, the same number of mobile agents and sites coexist in the system, is proposed for achieving the timeliness property. The response time in the system is conformed by those transactions that require coordination and those that can be satisfied immediately. In accordance, the distribution of the data in the system for coordination is a medullar issue for the improvement of the response time. A trade-off exits between these two kind of transactions depending on the coordination of the Mobile Agents, the capacity of allocating data among the sites, and as well as the distribution of the data and user requests in the system. In this sense, since the system requires high response time, a data allocation technology in which each mobile agent autonomously determine its own capacity for adjusting data among the sites is proposed. Thus, the system will adapt itself to the dynamic environment. The effectiveness of the proposed architecture and technologies are evaluated by simulation.
