Abstract
Quality of live video streaming technology is based on quality of Experiences parameters (QoE). Approaching the peer-to-peer (P2P) or peer-assisted networks as a sympathetic solution is highly required, especially in light of its authentic scalability and its extremely low initial cost requirements. However, the design of robust, efficient, and performing P2P streaming systems remains a high challenge when real-time constraints are part of the quality of service (QoS), as in TV distribution or conferencing applications. One of the P2P main issues that affect the quality of streaming is the neighbor selection methodology. The proposed work presents an effective mesh-based neighbor selection approaches for video streaming – Uniform Peer Distribution Algorithm (UPDA) – based on QoS and QoE Parameters. UPDA shortens the latency to be ranging from 10 ms to 50 ms servicing up to 4000 online peers under failure / recovery tests. Simulation results demonstrate that the proposed UPDA achieves good performance in End-to End delay with a percentage of 10.4 % and packet delay variation about 2% compared to random neighbor selection method.
Highlights
The predicted percentages for the total aggregation of all forms of video (TV, video on demand [VoD], Internet video, and Peer-to-Peer [P2P]) will be in the range of 87 to 95 percent of global consumer traffic by 2022 [1]
The contribution of this paper is to present a new peer-to-peer selection algorithm (Uniform Peer Distribution Algorithm (UPDA)) for live video streaming
The paper concern is the overlaying network as a real implementation for peer to peer video streaming network and its quality of service (QoS) measurements which are directly related to the quality parameters for the customer are as follows
Summary
The predicted percentages for the total aggregation of all forms of video (TV, video on demand [VoD], Internet video, and Peer-to-Peer [P2P]) will be in the range of 87 to 95 percent of global consumer traffic by 2022 [1]. Peers contribute their storage space to allow others to download demanded file conveniently and efficiently, even when the main peer/server source of the file is not available. Each peer contributes its effective upload bandwidth to reduce the bandwidth requirement of streaming server, to satisfy the timing constraint of streaming media playback and to increase the system scalability [2, 3]. The traditional topology for Multimedia AudioVideo streaming was the client-server networks due to their stability, but some challenges facing the client-server model such as the scalability problem need more CDNs and this increases the cost factor. It has a reliability problem due to unexpected leave of any fledged peer from the network at any time. Peer selection schemes are categorized into two categories: aware [4,5,6,7,8, 20] and non-aware (random) QoS selection techniques [2, 10, 13, 17, 18]
