Delay-constrained minimum cost multicast tree algorithm
时延受限费用最小多播树算法

Based on the Random Selective Tree Node First (RSTF) algorithm that constructs minimum cost multicast tree and considering the delay of the network, this paper presented a new algorithm constructing delay-constrained minimum cost multicast tree. The simulation about random network model shows that compared with KPP the new algorithm has better performance in terms of cost and time delay.
