Performance Analysis of Transport Protocol for Video Traffic (MPEG-4) Over WiMax

MPEG-4, Performance Analysis, RTP, DCCP.Abstract
In this project our focus is on the performance of two new protocols like Real
Time Protocol (RTP) and Datagram Congestion Control Protocol (DCCP) is to determine
which protocol can better meet the Quality of Service (Qos) for MPEG-4 video traffic over
WiMAX network. Based on the our simulation results obtained in this analysis it is
observed that both RTP and DCCP is better throughput than UDP. For video traffic load of
4Mbps, throughput achieved by both RTP and DCCP is almost 100% without expressing
any packet loss. With the increase of video traffic load of 5Mbps and beyond RTP maintains
its throughput and it shows minimum packet loss but DCCP losses its performance. Delay
behavior of RTP also indicates that its performance is better than the DCCP. According to
our simulation results RTP better satisfies the quality of service than DCCP for transport of
multimedia (video) traffic. Mobile Multimedia is an attractive and promising application
which allows immersive communication and discussion among people at different and
distant places. However, its stringent delay and bandwidth requirements limit its scale and
spread over current Internet. The Mobile multimedia application has increased
enormously. Currently most of the multimedia application use as the main transport
protocol, However UDP performance has not been satisfactory various factors, in
multimedia application. A number of new protocols are being developed to meet the
diverse needs of emerging multimedia applications. RTP and DCCP are two important
developments are being considered in this regard. In this project, through simulation,
performance of, RTP and DCCP protocols has been analyzed for the transport of MPEG_4
video traffic Over Mobile WiMax as underlying access technology. Considering single cell
WiMax network, performances metrics such as throughput, delay, pack loss and jitter have
been determined for each of the four protocols in varying WiMAX network topology.
