摘　　要：针对基于NS2的网络性能仿真可信度评估,提出了一种新的基于置信区间的可信度评估方法.该方法根据实际需求选择合适的置信水平,计算出合理的置信区间,观察相同条件下仿真结果样本均值在置信区间上的分布,对仿真结果可信度进行评估.通过实际系统和仿真模型对比验证,证明在高置信水平下,仿真结果可信.In view of simulation result degree of confidence based on the NS2 network performance,a new approach was proposed based on confidence interval.An appropriate confidence interval was selected according to the actual requirements,through the distribution of simulation results in confidence interval assessed the confidence degree of simulation results.Through the analysis of an actual system and the simulation model showed that the simulation results are credible under the high confidence level and has provided a beneficial reference for the degree of simulation confidence research.
