A secured channel for transmitting multimedia contents in peer-assisted networks

The Internet's explosive growth has raised demand for effective online video streaming services and cast doubt on the viability of peer-to-peer (P2P) networks and conventional content distribution networks (CDN). To facilitate efficient video streaming, Peer-Assisted Networks (PA-CDNs) integrate the best aspects of P2P networks and CDNs. Transferring data content across a protected channel platform is crucial since the PA-CDNs strategy uses both servers and peers, optimizing both delivery methods to offer the best possible user experience. However, it is vulnerable to assaults. By guaranteeing secure access management and addressing security concerns, this study offers a strong security model to strengthen and improve security in PA-CDN network environments. The outcome of the experiment indicates that the strategy works. Strong security model to strengthen and improve security in PA-CDN network environments.

REAL-TIME INTERACTIVE MECHANISM FOR LIVE STREAMING ON PEER-TO-PEER NETWORKS

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.

AyoPeer: The adapted ayo-game for minimizing free riding in peer-assisted network

Peer-assisted networks have recently emerged as an excellent tool for distributing video contents across the Internet. High peers’ participation and cooperation in peer-assisted networks can drastically reduce the bandwidth cost, increased scalability and ease of deployment. However, the main factor which limits effective distribution of resources in this network is free riding; a situation in which a peer consumes resources freely but refuses to service other peers. This paper presents a new peer-assisted streaming model (AyoPeer) using game theoretics with the aim of minimizing free riding.The interactions between peers are fashioned after a famous Yoruba game called “Ayo”. AyoPeer provides a reward and punishment mechanism that ensures the free-riders fail and cooperating peers succeeds with download. The experimental results revealed that AyoPeer mechanism outperform the existing scheme by ensuring fair distribution of resources, high cooperation among peers and resistance to free-riding peers.
