Hierarchical peer-to-peer overlay with cluster-reputation-based adaptation
Chih‐Lin Hu, Tzu-Han Kuo · 2009
This paper proposes a hierarchical cluster-based peer-to-peer overlay scheme based on both of partially-centralized and semi-structured overlay models in light of network locality and proximity. This joint design can keep up system efficacy and flexibility in dynamic networks where peer churn, peer mobility and search redundancy become stickier. In addition, a special reputation tree is exploited to mitigate the free-riding problem over a large-scale system. By simulation results, the proposed scheme can react to above issues without loss of prominent performance.
