Varied P2P trust models have caruso rhodiola been proposed recently; it is necessary to develop an effective method to evaluate these trust models to resolve the commonalities (guiding the newly generated trust models in theory) and individuality (assisting a decision maker in choosing an optimal trust model to implement in specific context) issues.A new method for analyzing and comparing P2P trust models based on hierarchical parameters quantization in the file downloading scenarios is proposed in this paper.Several parameters are extracted from the functional attributes and quality feature of trust relationship, as well as requirements from the specific network context and the evaluators.Several distributed P2P trust models are analyzed quantitatively with extracted parameters modeled into a hierarchical model.The fuzzy inferring method is applied to the hierarchical modeling of parameters to fuse the evaluated values iphone 14 price miami of the candidate trust models, and then the relative optimal one is selected based on the sorted overall quantitative values.

Finally, analyses and simulation are performed.The results show that the proposed method is reasonable and effective compared with the previous algorithms.
