The video player plays a vital role in presenting the streaming video which is utmost important for content providers. It has a huge impact on user experience. Wireless networks are vulnerable to noise, interface and have bandwidth limitations. Due to the intrinsic vulnerability of the communication channel and large number of variables involved, simulations alone are not enough in the evaluation of the performance of the wireless networks and performance of the video in the player is to be considered. When there are disturbances or shortages of capacity in the network, network disconnection or sender failure, the video player stops.
