A shared-route decision algorithm for efficient multicast routing

The shared-route decision algorithms in multicasting communications networks to provide the Internet-based services such as IPTV, remote education/health, and Internet broadcasting are presented. The three main measures of maximum delay, average delay and estimated delay between each node and member are adopted. Under the Mesh network with the uniform random cost between each node, the algorithm's performance is compared to the optimal solution with the minimum cost by all enumeration. The simulation results show that the algorithm using the estimated delay outperforms the other two methods.
