| 摘 要： | 在研究了当前时延推测算法的基础上,将高斯混合模型推广到有限混合模型,使得算法可以同时推测多条链路的时延分布,利用重要性抽样技术增大研究事件出现的概率,再进行抽样并对样本空间进行调整,保证了指标的无偏性和有效性,同时降低了计算的复杂度,因此此方法具有广泛的适用性。最后在NS2平台上仿真验证,说明该算法是可行的。

| Abstract: | In the study of the current delay speculate algorithm based on gaussian mixture model extended to limited hybrid model, which makes the algorithm can at the same time more than that of the link delay distribution, the importance sampling technique increases the probability of the event, and then to sampling and sample space to adjust to ensure that the index of the unbiasedness and effectiveness, and at the same time reduces the computational complexity, so this method has wide applicability. Finally in the NS2 simulation test platform, show that the algorithm is feasible. |
