摘要
为解决目前OPNET无法综合评估战术互联网视频业务的缺陷,提出了引入视频评估算法进而利用MATLAB与OPNET进行联合仿真评估的新思路,重点通过仿真讨论了目前常用视频评估算法的优劣,指出VQM算法具有较高的评估准确性。鉴于VQM算法参数取值不精确的弊端,提出用超定方拟合的方法对算法进行优化,仿真结果显示优化后的算法评估准确性较高,可以成为MATLAB与OPNET联合评估的建模依据。
In order to solve the shortcomings of the current OPNET' s disability of evaluating the video service comprehensively, the new idea of applying the video evaluation algorithm and then evaluating through the joint simulation of MATLAB and OPNET is proposed. The advantages and disadvantages of the commonly used video evaluation algorithm are discussed with emphasis through simulations. It is pointed out that high evaluation accuracy is achieved through VQM al- gorithm. Due to the inaccuracy of the parameters of VOM algorithm, the method of overdeter- mined squre fit over the optimization of the algorithm is proposed. The simulation results show that the optimized algorithm is accurate enough to be the basis for the joint evaluation of MAT- LAB and OPNET.
