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.
