Application layer multicast tree for real-time media delivery

This paper presents an application layer multicast tree to minimize the average time delay between the sender and end-systems for the real-time media delivery. The proposed algorithm also takes into account the computing power and the network condition of each end-system as a control variable in order to avoid the undesirable case that end-systems are overloaded considering their limited resources. The multicast tree is constructed by clustering and modified Dijkstra's algorithms. Finally, we provide the experimental result and compare the proposed algorithm with other algorithms to show that it can provide an effective solution.
