A smoothing variable step size algorithm

In this paper, both Long Range Dependence (LRD) and burstiness are illustrated to show traffic characteristics of original frame sequence can be represented by traffic on the time scale of GOP. A new smoothing variable step size adaptive (S-VSSA) algorithm is presented based on fix step size adaptive (FSSA) algorithm and variable step size adaptive (VSSA) algorithm, which are used to predict MPEG-4 video traffic on large time scale of GOP. And S-VSSA algorithm can improve performance of prediction significantly according to a number of simulations. The new algorithm can achieve fast convergence and small prediction error.
