Abstract: 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 obtamed by calculating an example, the analysis to result indicates that this model is effective and feasible, and has scicntificalness and rationality.
