SAM: A Simplified Seasonal ARIMA Model for Mobile Video over Wireless Broadband Networks

摘要

Wireless broadband technologies like WiMAX2 are spreading especially in areas where wired broadband is not expected to reach. Video streaming is continuously acquiring a larger share of Internet’s traffic resulting in a need to have a reliable video traffic model. In this paper, we analyze several video streams compressed for mobile streaming and develop their optimal Seasonal ARIMA models. Although these optimal models are very different, we find that a simple model, which we call Simplified Seasonal ARIMA Model (SAM), represents all of the streams very well. This model is ideally suitable for video generation in mobile video simulation studies. We also present the parameter values suitable for such studies.
