When applied in a commercial deployment, DHTbased P2P protocols face a dilemma: although most real-world participants are so unstable that the maintenance overhead is prohibitively high, they must be effectively utilized due to the lack of stable participants. Thus, determining how to leverage unstable nodes to enhance system scalability and then maximize stability in high-churn scenarios becomes a substantial problem. This paper focuses on this topic, and the main findings are two folds: this paper proposes a homogeneous grouping scheme for scalability enhancement. Besides extending system storage capacity by admitting all nodes.
