Abstract:
Using Peer-to-Peer (P2P) overlay networks have become a progressively popular approach for streaming live media over the Internet due to their scalability and deployment simplicity. In this project, we have proposed a hybrid push-pull live P2P video streaming protocol called PPM that combines the benefits of pull and push-based mechanisms for video delivery. The main goal of this research is to minimize the network end-to-end delay in comparison to pure mesh networks. The low end-to-end delay is achieved through two phases: the first phase is to select a parent node based on peers’ overlay hop count in a mesh topology and the second is to construct a dynamic tree in order to push the most important video frames within the tree. Using OMNET++, we show that beside the end-to-end delay, the video distortion achieved is lower in comparison to a pure mesh network. Simulation results confirm the superiority of the proposed protocol compared to the existing mesh-based P2P streaming systems.
