Efficient neighbor selection through connection switching for P2P live streaming

WidePLive: a coupled low‐delay overlay construction mechanism and peer‐chunk priority‐based chunk scheduling for P2P live video streaming

“…In conventional mesh-based systems, peers connect to each other in the order of entry and each peer can serve a limited number of neighbours due to limitations in peers' upload bandwidth. This procedure makes the distance between the new peers and the video server more than the previous peers, and their playback latency may be higher than previous peers [21]. Kim et al [21] proposed a neighbour selection scheme called connection switching to reduce the average playback latency in the system.…”

“…This procedure makes the distance between the new peers and the video server more than the previous peers, and their playback latency may be higher than previous peers [21]. Kim et al [21] proposed a neighbour selection scheme called connection switching to reduce the average playback latency in the system. The focus of their proposed method is to give the chance of connecting to intermediate peers to new peers.…”

“…In this scheme, when a new peer enters the system, if the two peers have a predefined threshold of buffer packets, their connection may be broken and then connected to the new peer. The proposed method in [21] has reduced the quality parameters including playback latency and startup delay in contrast to the conventional method. In [8], a three-stage peer selection strategy is proposed for managing the delay in meshbased P2P live streaming systems.…”

“…In addition, as the major contribution of this paper, we coupled low-delay overlay construction mechanism and peer-chunk priority-based chunk scheduling that use a prioritybased peer selection strategy as a coupling feature for overlay construction and chunk scheduling mechanisms to achieve simultaneous reduction of playback latency and decrease startup delay and increase playback continuity compared to previous works. We performed extensive simulations to demonstrate the higher performance of WidePLive compared to the conventional policy and the proposed scheme in [21]. Results show that playback latency and startup delay in WidePLive is less than playback latency and startup delay in the conventional scheme and also the proposed scheme in [21].…”
