Research on NS-2-Based Simulation Method for Video Stream

WANG Ming-wei,WANG Qi,YANG Jie,LIN Jian-zhong(College of Telecommunications and Information Engineering,Nanjing University of Posts and Telecommunications,Nanjing 210003,China)  
MPEG standard codes the video sequences to frame I,P,and B,and has higher compression rate and bandwidth saving character.Following the deployment of networked multimedia applications,such as video conference,simulation research on video stream characteristic is more and more important.MPEG video traffic characteristic and simulation methods are researched in this paper.Network simulation version 2(NS-2) kernel is extended using C/C++ programming language.An MPEG video traffic generator modules and simulation interfaces are designed in NS-2 kernel.Simulation results show that the proposed extension method is feasible and effective.
