  7. Abstract:
  8. Overlay Peer-to-Peer networks opposed to their high scalability and more robustness against network errors, are more considerable rather than other content distribution approaches such as Client/Server and multicast video streaming. At this thesis we investigate the video streaming over these networks, which includes more than half of internet traffic nowadays.Localized video streaming is one of the techniques for improving quality of service (QoS) over peer-to-peer networks. With localization techniques, video chunks distribute among neighbors that have more proximity with each other and traffic is held localized over the network.We proposed a new metric for estimating network proximity of peers used in receiver-side scheduling, called “Down-Distance” which equals to the one-way time required for transferring data from a neighbor, and we want to apply localized streaming based on this metric. At this thesis after survey on the related works of localized video streaming, we’ll present requirements and implementation details of our proposed approach.Finally we present some simulation scenarios at OMNET++ environment for evaluating our proposed approach with two approaches include Randomized streaming and RTT Localized streaming. These scenarios have been considered at homogeneous and heterogeneous bandwidth network for live video streaming. Results of our simulations shows that quality of service metrics have improved at localized streaming approaches, especially our proposed approach
