A novel hierarchical community architecture with end-to-end delay awareness for communication delay enhancement

摘要

The extreme dynamism and the rapidly changing user's requirements in current information systems promote imperative needs for the autonomous community information system (ACIS) proposition. ACIS is a decentralized architecture that forms a community of individual end-users (community members) having the same interests and demands in somewhere, at specified time. It allows the community members to mutually cooperate and share information without loading up any single node excessively. In this paper, an efficient autonomous decentralized community construction technique is proposed to reduce: the communication delays among members with take into consideration the latency among them and the required time to join/leave. This technology organizes the community members into a hierarchy of sub-communities. This paper illustrates the step-step construction technique and the membership management operations for the proposed hierarchical community structure. In addition, it studies the community communication among members to quantify and study the tradeoff between the communication delay and the membership control (join/leave) overhead.
