Error models simulations in transmission channels using network simulator environment

This paper discusses transmission channels evaluation, error models and their subsequent simulations for the transmission of video content. To create a network topology and error channel models, NS-2 environment is used. In this paper, we simulated two basic error channel models, namely Gilbert-Elliot and Binary Symmetric channel model. Network traffic in topology is created by NT-MyEvalvid2 toolkit, which also serves to evaluate the data transferred and their subsequent visualization. In paper, we compare the measure of packet loss when using these error models with different input parameters and their impact on the quality of video transmission parameter evaluated by PSNR.
