With the development of broadband technologies, more and more multimedia contents such as video or bulk file are being distributed over the Internet. However, an important issue to be resolved is how to construct an efficient overlay to provide users with the acceptable throughput and delay, while receiving multimedia contents. Therefore, this paper designs a tree construction algorithm by distributing...
This paper designs a tree construction algorithm by distributing the layered steaming over the ALM in order to improve both the throughput and user delay. Firstly, by carrying out theory analysis, we define an out/in degree and the corresponding constraints to manage the layered streaming and nodes to improve the throughput. Besides, a novel method, called ALM-Bi-cast, is also proposed and analyzed...
This paper presents a novel approach for efficient tree construction in ALM (application layer multicast) using layered video coding. This system is suitable for the users in heterogeneous environment such as xDSL and CATV, where upload and download speeds are different. We point out some problems in these environment of the ALM and show their solutions at two stages. First, we redefine the "degree...
