  7. Abstract:
  8. Peer-to-peer streaming has developed as a popular application in today’s Internetinfrastructure. In a typical peer-to-peer live streaming system, publishers provide the streaming content and the interested peers receive and deliver data in a distributed manner and also apeer structure is created by forming an overlay inside the network. In reality, peers are strategic and there is no motivation to contribute any of their upload bandwidth toward other peers. To address this issue, we proposed a simple arcade algorithm that makes an arcade based mechanism for peers to facilitate adjacent peers with more bandwidth to achieve a higher bandwidth themselves.Commensurate with our algorithm, if peers want to achieve their required perceived video quality, they have to win the competition of attracting the publisher’s decision by increasing their network contribution sequentially. As a result peers make publishers’forwarding bandwidth free by preventing other peers joining publishers directly. This motivates publishersto allocate the contributed peers with higher bandwidth.We simulated a live streaming mesh-based peer-to-peer network with OMNET++ network simulatorand compared our results with popular infrastructure of CoolStreaming. Our results show that our algorithm improved the performance metrics in comparison to the previous implemented solutions.
