Multivariate statistical technique over QoS variables to analyze video quality metrics on IEEE 802.11ac networks

Abstract

Resumen-We present the results from a measurementbased performance evaluation of wireless networks based on IEEE 802.11ac standard in an indoor environment, with the aim to analyze their performance under high definition streaming video applications. We focus our study on analyzing the highest performance of these standards using off-theshelf equipment as well as the behavior of Quality of Service variables and how they affect to the video quality. Thus, we have analyzed and measured these variables and have applied a multivariate statistical technique, called Factor Analysis, and finally discuss their behavior.Palabras Clave-multivariate statistical technique, factor analysis, video quality metrics, quality of service, quality of experience
