SWOR: An Architecture for P2P Scalable Video Streaming Using Small World Overlay

In this paper we propose SWOR, an architecture to deliver Scalable Video Coding (SVC) contents over P2P network. SWOR architecture is based on twofold mechanisms: (1) organization of peers in Small-World (SW) overlay networks, (2) delivering SVC content using push-pull mechanism. SWOR is evaluated and compared with CoolStreaming/DONet (CS) on QoS metrics using NS-2 simulator. Performance evaluation demonstrates that SWOR outperforms CS and provides a significant improvement in the received video quality in terms of lowering the packet loss and transmission delay.
