Cooperative channel resource sharing in P2P networks
Istiaque Shahriar, Dongyu Qiu, Brigitte Jaumard · 2014
There is an increasing number of channels with a limited number of viewers in multi-channel live streaming systems. Such channels suffer from poor channel performance. As a result, when a viewer explicitly requests for a block of streaming content, the probability that the requested block of data will be available among the existing viewers is less than what is required in order to offer a continuous playback. In this work, we propose a novel scheme of cross-channel resource sharing, in order to solve the performance problem of the dedicated channels or channels having a small number of viewers due to their limited number of viewers. We next develop a discrete-time stochastic model for analyzing the performance issues of the proposed scheme and provide insight into it. Experiments showed that our proposed scheme allows an improvement of the performance for the viewers of the channels having a limited number of viewers.
