| Abstract: | In this paper, ARLNCStream, a novel algorithm of adaptive random linear network coding for media streaming, is presented. When distributing contents using random linear network coding, every node adjusts its coding window in an adaptive way and then requests coded block of an appropriate size from its partners. The solution makes nodes collaborate well with potential partners. Without knowledge of global network topology, ARLNCStream archives quiet low segment missing ratio. ARLNCStream is also robust and scalable. Simulations demonstrate the excellent performance of the solution. |
