Research on a P2P supper node selection mechanism based on trust model

摘要

This paper presents a P2P super node selection mechanism based on trust model, in which overall trust degree is an important item to evaluate super node, introducing reward-penalty factor and time decay factor into computing trust degree of node, selecting alternative super node set from common nodes by threshold filtering, and then to select the optimal node from supper node set as super node. The mechanism can enhance correctness of selecting P2P super node effectively by simulation under MatLab.
