Abstract

With the development of broadband wireless network technologies, the demand on video streaming technologies over wireless network has increased drastically. P2P streaming technology is adopted in the wireless environments to expropriate the demand on mobile video, because of its scalability. However, the wireless channel condition varies from time to time due to several reasons, such as node’s movement, symmetric resource allocation, etc. It is hard to provide P2P streaming services in wireless environments, because it is not easy to guarantee the upload and download bandwidth. In order to ensure overall service quality in mobile P2P streaming environments, an unchoking algorithm, that reflects the time-varying wireless channel status, is necessary. In this paper, we propose the adaptive unchoking algorithm that determines the maximum number of unchoked peer, depending on the network status and selects the peers to exchange the stream piece (chunk).
