Autonomous Information Fading and Provision to Achieve High Response Time in Distributed Information Systems

Abstract

In highly dynamic electronic commerce environment, the need for adaptability and rapid response time to information service systems has become increasingly important. In order to cope with the continuously changing conditions of service provision and utilization, Faded Information Field (FIF) has been proposed. FIF is a distributed information service system architecture, sustained by push/pull mobile agents to bring high-assurance of services through a recursive demand-oriented provision of the most popular information closer to the users to make a tradeoff between the cost of information service allocation and access. In this paper, based on the analysis of the relationship that exists among the users distribution, information provision and access time, we propose the technology for FIF design to resolve the competing requirements of users and providers to improve users' access time. In addition, to achieve dynamic load balancing with changing users preference, the autonomous information reallocation technology is proposed. We proved the effectiveness of the proposed technology through the simulation and comparison with the conventional system.

Autonomous Coordination Technology to Achieve Continuous Service in Autonomous Decentralized VoD Systems

“…The main goal of FIF system is to guarantee the assurance of autonomous information service provision and utilization [4]. Service providers trace the demand trend for information, and allocate to accepting storing nodes the most accessed segment of their information services.…”

“…In the FIF system, information contents are uniquely defined by Content Code (CC) [4]. Service providers transmit information services through Push-MAs by specifying content codes (CCs) of information to the nodes.…”

“…The system is constructed based on the Faded Information Field (FIF) architecture [4]. In the system, video data is encoded into different quality layered data, which stored in separated nodes distributed in different levels.…”

Autonomous Information Services Integration for High-Assurance in Demand-Oriented Information Systems

“…In order to reduce network traffic and improve users' access time, we have been developing a demand-oriented architecture called Faded Information Field (FIF), sustained by Push/Pull mobile agents [5]. The characteristic of the FIF is to balance the cost of information allocation performed by push mobile agents and the cost of the access to the information performed by pull mobile agents [2].…”

Autonomous Timeliness and Reliability Oriented Information Services Integration and Allocation in Multi-Agent Systems

“…In the FIF, the service provider (SP) allocates its popular information to adjacent nodes, closer to users. The characteristic of the FIF is to balance the cost of information allocation performed by push mobile agents and the cost of the access to the information performed by pull mobile agents [4]. The information structure consequently permits to preserve the same access time to all unspecified users, whatever their current demand trend and volume.…”
