Dynamic Mechanism for Video Streaming on Peer-to-Peer Networks using OPNET

Quality for live video streaming technology is based on quality Experiences parameters (QoE). Approaching the peer-to-peer (P2P) or peer-assisted networks like sympathetic solution is highly required, especially in light of its authentic scalability and its extremely low initial cost requirements. However, the design of robust, efficient, and performing P2P streaming systems remains a big challenge when real-time necessity are partnof the quality for service. One of the P2P main issues is the neighbor selection methodology. The proposed work is an operative mesh-based neighbor selection algorithm for live video streaming based on QoS and QoE Parameters. We simulates different scenarios up to 4000 online peers under failure / recovery tests. The simulation results demonstrates that the proposed algorithm achieves good performance in end-to-end dela variation..A new algorithm “UPDA” used to improve streaming quality though a new neighbor selection methodology. This categories peers into super peer and slow peer."APDA" algorithm that defines the role of each peer existing in the streaming session. With the coming of services and applications such as media and videos streaming over the internet. some server service model a client must made request to the video server,CDN (Content Delivery Network ) approximation a set of CDN server are set on at the network instead by downloading the video from the multimedia server.
