“…Such solutions can be classified roughly into tree-based systems or mesh-based systems [7], [8]. In tree-based systems, nodes are organized into a tree structure and information flows down one or more trees [7], [9], [10]. In mesh-based systems, there is no particular structure and nodes exchange information directly with one another, dynamically changing their neighbors over time, similar to epidemic dissemination [8], [11].…”

Tree-based systems rely on real-time dissemination trees to deliver information to nodes. In order to offer good services, two fundamental aspects should guide the real-time growth process: low node degree and short distances to the server. In this paper, we propose a growth process to construct trees and make a detailed study on modeling and performance analysis of these tree-based systems. Our generative mechanism is based on the preferential attachment principle, where preference is given in terms of node quality. The proposed growth mechanism has a single parameter to weigh the relative importance of node degree and node distance on assessing node quality. We aim at understanding this mechanism when considering the local aspect of the node's degree and the global aspect of the distance to a source. With this goal, we investigate our model through simulations and compare it to other growth processes. Our results indicate that the proposed model is capable of self-organizing nodes into good trees under six metrics of interest.INDEX TERMS Preferential attachment, Real-time growth process, Tree-based systems, Node quality, Recursive tree, Random tree, Random recursive tree, Power of two choices.

“…In Figure 3 we plot the floor of the solution of Equation (10), for n = 600 and n = 60, 000. As α increases from 0.1 to 1.0, the optimal degree decreases from 14 to 1, corresponding to a transition from graphs favoring smaller distances to smaller degrees.…”

“…In order to provide scalability and decentralization, in some studies, peers are clustered into several tree based systems [6,7,23,43]. The cluster leaders send video packets to the peers in their clusters in NICE [6], NEMO [7] and ZIGZAG [43]; and the links between the leaders and ordinary peers compose multicast tree.…”

In this paper, we propose a new multicast tree framework to be used in peer-to-peer (P2P) live video streaming systems. The proposed system, adapts the tree links under high peer churn and runs in a totally distributed manner. In order to provide this dynamism and seamless streaming at the same time, we propose a cross layer design involving scalable video codec, backup parents and hierarchical clusters. The performance of the system is measured in real world environment PlanetLab that has nodes distributed all over the world. The experiments show that the proposed system provides high quality of experience (QoE) in terms of Peak Signal to Noise Ratio (PSNR), playback delay and duration of pauses. The proposed system also provides incentive mechanism to its users.
