A study on suitable range of packetization interval for streaming application over WLAN

Abstract

Ensuring satisfactory Quality of Service (QoS) is a vital consideration in deploying multimedia streaming service, especially when deploying over wireless network. Selecting suitable parametric values for each streaming parameter is one of a crucial factor. This work is concerned with one of the parameters commonly known as `Packetization Interval' which has direct influences on several critical QoS parameters such as packet loss, packet delay and jitters. The experiment on finding a suitable range of packetization interval had been carried out by means of simulation using INET Framework for OMNeT++. The simulations were carried out based on the basic service set scenario in both no interference and coexistence with background traffics. The result reveals that the commonly recommended default packetization interval of 20 ms. fails to yield satisfactory QoS in many scenarios. The study also indicates that a suitable packetization interval for scenarios under this study or similar ones ought to be set within the range of 40 ms-70 ms. The paper also discusses the findings and applications are suggested.
