Super-peer Selection Mechanism with Incentive in P2P Network
Huo Ying · Journal of Chinese Computer Systems · 2011
The performance of P2P networks have decreased severely because of the large number of free-riders.How to incentive nodes to provide service is an important factor to improve the performance of P2P networks.Differing from the general super-peer selection which is only based on physical capability and unconsidered free-riding,super-peer selection mechanism with incentive(SSMI) is presented in this paper considering physical capability,voluntary and anticipation to future.The node is selected as the super-peer by each node′s utility and endow super-peer with supervising privilege in SSMI.It′s been shown that the SSMI increases the total number of file shared,improves the file querying success rate,decreases the average querying hops,and ensures the cost is small at the same time in the Simulation experiments.The Super-peer overlay of SSMI is steady and robust.
