DLPSPN: New Efficient Super-Peer Network Based on Double-Loop Petersen Graph

Super-peer network adopts two-layer based architecture helps to improve the network performance and the search efficiency. While the dynamic maintenance and broadcast routing mechanism of network topology has an important influence on these two properties. Existing network topology structure has some defects, such as complex maintenance and consuming an excessive amount of bandwidth. This paper proposes a new scalable topology structure based on double-loop Petersen graph, and a new super-peer network DLPSPN, which greatly reduces the maintenance complexity and the bandwidth consuming compared with existing super-peer networks. The efficiency of DLPSPN is also verified by theoretical analysis and simulation experiments.
