Cooperative video broadcasting in heterogeneous network environment

In this paper, we propose a peer-based cooperative streaming framework with the use of broadcast capability of the network. The basic idea is to ask the concurrent high-end machines denoted peer server to cooperate to broadcast a video encoded by layered coding to clients. This transmission strategy aims to take the benefit of peer-to-peer (P2P) and video broadcasting for video delivery. Due to the dynamic nature of the P2P environment, the system performance of the proposed framework depends on the factors of the central server resource supplied, the number of peer server recruited and the minimum quality levels acquired. Hence, the main focus of this paper is to explore the relationship among these factors in the proposed architecture by an analytical model.
