A Methodology for Characterizing Real-Time Multimedia Quality of Service in Limited Bandwidth Network
Abstract: This paper presents
how to characterize the quality of multimedia which consists of audio and video
that are transmitted in real-time communication through the Internet with
limited bandwidth. Wedeveloped a methodology of characterizing the multimedia
Quality-of-Service (QoS) by measuring network parameters (i.e., bandwidth
capacity, packet loss rate (PLR), and end-to-end delay) of testbed network and simulating
the audio-video delivery according to the measured network parameters. The
analysis of network parameters was aimed to describe the network
characteristics. Multimedia QoS was characterized by conducting a simulation
using data which was collected from the previous network characterization. A simulation
network model was built using OMNet++ representing a delivery of audio-video in
real-time while a background traffic was generated to represent a real
condition of the network. Apllying the methodology in a network testbed in
Indonesia’s rural area, the simulation results showed that audio-video could be
delivered with accepted level of user satisfaction.
