Autonomous Decentralized Community Construction and Reconstruction Technology for Service Assurance

Recent headway in the domains of mobile communication and ubiquitous computing has given surge of interest to mobile commerce applications. Current information systems promote concept of information service provision to anyone, anytime and anywhere. Autonomous Decentralized Community System has been proposed to meet the varying requirements of users. In this paper, the decentralized search service is taken up as an application. This retrieves service in which the service offer end time has been decided beforehand. Needs of this application are the accuracy, the adaptability, and the improvement of the assurance is requested. There are two requirements in this service. First, it is to prevent the network being crowded with the request message from the node where SP that can enjoy serving doesn´t exist. And, it is to prevent the stability of the entire system from decreasing to update cash information. To solve these, it proposed the Autonomous Construction Technology and the Autonomous Change Adjustment Technology. Simulation results demonstrate the effectiveness of proposed technology in terms of improvement in service assurance and confirms the trade-off between accuracy and system stability.
