Overlay optimization for Peer-to-Peer scalable video streaming

Video streaming with Peer-to-Peer (P2P) architectures and Scalable Video Coding (SVC) appears to be an interesting solution for an efficient streaming in the heterogeneous scenario of Internet applications. A key issue in such approach is the optimization of the bandwidth capacity of the P2P system. In this paper we propose an innovative approach for the network overlay optimization based on Integer Linear Programming. The proposed approach is particularly suitable in case of push-based solutions for video streaming using SVC with prioritized content. The simulation results show the flexibility of the proposed model when used to generate an overlay following different constraints and operational requirements. The usability and the computational complexity of the proposed method is also analyzed when the overlay includes an high number of peers.
