On the perceived quality evaluation of opportunistic Mobile P2P Scalable Video streaming

TLDR
Different scenarios have been introduced in this paper towards evaluating the video streaming policy in the MP2P system, using a real-time probabilistic Fractional Brownian Motion (FBM) and a Random Waypoint (RWP) Mobility model.
Abstract
This paper studies the evaluation of the video streaming over Mobile Peer-to-Peer (MP2P) networks using Scalable Video Coding The proposed research framework exploits the MP2P diversity characteristics where each node acts as a Mobile Peer for every neighboring node in a relay-based communicating path Mobile Peers use a common look-up table to request video streaming resources in order to estimate the video packets transfer duration in the end-to-end path The collaborative streaming is achieved through the data packets replication policy, which uses a bounded upper time limitation for the video packets of each layer (Use of Scalable Video) Each node/device utilizes a specified amount of capacity for both channel and storage purposes Different scenarios have been introduced in this paper towards evaluating the video streaming policy in the MP2P system, using a real-time probabilistic Fractional Brownian Motion (FBM) and a Random Waypoint (RWP) Mobility model In both models, nodes move according to certain probabilities, location and time Intermittent connectivity occurs while nodes claim video streams, whereas promiscuous caching policy enables -where possible- recoverability of lost packets offering priority to packets from the base layer The simulation results show that FBM provides better objective and subjective quality results for two video sequences resolution, in the MP2P network configuration

Enabling resilient P2P video streaming: survey and analysis

TL;DR: This paper first classify the different challenges that face P2P streaming and then present and analyze the possible countermeasures, and analyzes resilience mechanisms as either core mechanisms, which are part of the system, or as cross-layer mechanisms that use information from different communication layers, which might inflict additional costs.
