Credible cooperative node selection model in hybrid streaming system
摘要
Abstract
To address the problem of selecting credible cooperative node in hybrid streaming system,this paper proposed a credible cooperative node selection model based on trust.In this model,servers primarily selected nodes with higher global transaction trust,better overall performance and longer past online time as cooperative nodes.The model was capable of resis-ting malicious attacks,by using the concepts of decay factor and recommendation trust during the calculation of trust.Deposit and digital signature mechanism further constrained the behavior of the selected cooperative nodes,and enhanced the model’s availability.Simulations demonstrate that the proposed model can effectively identify malicious nodes and improve the system’s user experience.关键词
