Autonomous Information Access to Assure Service Level Agreement in Faded Information Field

The user differentiation is required to attain heterogeneous service levels in such terms as accessible information volume, response time, or system availability. To fulfill requirement of user differentiation to attain heterogeneous service levels, based on the Faded Information Field (FIF) system architecture, autonomous real-time navigation technology is proposed by navigating users' mobile agents to low-congestion nodes to assure the maximum response time. As a result, the requests are able to avoid local congestion zones without a centralized dispatcher or workload manager, leading to globally accomplishing the heterogeneous Service Level Agreements of each user even in case of subsystem failure and rapidly changing environment. The effectiveness of the proposed technology has been proved through simulation, and the results show that the proposed technology increases an average of 60% the service satisfaction ratio.
