A Global Trust Model of P2P Network Based on Distance-Weighted Recommendation

摘要

We propose a global trust model, which is based on the distance-weighted recommendations under P2P circumstance, with the modelpsilas mathematical expressions and realization methods under distributed circumstance, to quantify and evaluate the credibility of peers. The results of the simulation show that our model is more tolerant under comprehensive attacks, and also makes significant improvements on the rate of successful downloading.
