To address the extreme dynamism and the rapidly changing user's requirements in current information systems, an Autonomous Community Information System (ACIS) has been developed. ACIS is a decentralized architecture that forms a community of individual end-users (community members) having the same interests and demands at specified time and location. It admits them to mutually cooperate and share information without loading up any single node excessively. ACIS does not embrace the advantage of heterogeneity of the community nodes-nodes latencies. In this paper, ACIS-Hierarchy, decentralized hierarchical community architecture is proposed. It considers latency between community nodes as an important criterion that need to be optimized. It takes advantage of heterogeneity of the community nodes-nodes latencies to improve the communication delay among the community. In this paper, an efficient autonomous decentralized community construction technology is proposed to reduce: the communication delays among members taking into consideration the latency among them and the required time to join/leave. This paper illustrates the step-step construction technology and the membership management operations for ACIS-Hierarchy. Experimental results show that ACIS-Hierarchy improves the community communication delay.
