不确定环境下的Ad-hoc网络可信性评价模型研究

Research about Evaluated Model for Creditability of Ad-hoc Network in Uncertain Environment

运用不确定理论解决了Ad-hoc网络可信性模型的评价问题。运用不确定理论对Ad-hoc网络的信任度进行分析、评价和测试,提出了不确定综合评判方法,建立了Ad-hoc网络的可信性评价模型。该模型首先采用不确定变量表示各个评判因子的权重系数,增强了各因子权重的合理性;然后通过单因子评价模型对各因子进行评价;最后利用不确定综合评判模型确定Ad-hoc网络整体的可信度标准等级。通过实例运算得出综合评价结果。结果分析表明,该模型有效可行,且具有科学性和合理性。

This paper solved evaluated problem to model for Ad-hoc network by uncertainty theory.The paper carried on analysis,evaluation and test to creditability level of Ad-hoc network by uncertainty theory,proposed uncertain comprehensive evaluated method,established credibility evaluation model for Ad-hoc network.At first,weight of each evaluated index was characterized as uncertain variable in this model,strengthened rationality of weight of every index.Then carried on evaluation to every index by single index evaluation model.At last,the creditability level for the whole Ad-hoc network was determined by uncertain comprehensive evaluated method.The comprehensive evaluated result was obtained by calculating an example,the analysis to result indicates that this model is effective and feasible,and has scientificalness and rationality.
