Delay-constrained fast low-cost multicast routing algorithm
一种快速低代价延迟受限组播路由算法

In order to satisfy the QoS requirements of real-time applieations, the algorithm added delay eonstrains upon a non-delay-constrained multicast routing algorithm FLSPT was proposed to ensure that the accumulated delay from source to any destination along the tree does not exceed the pre-specified bound, as well as keep the outstanding performance on time complexity and cost of it. Simulation results show that, our algorithm outperforms DCSP in terms of cost and time complexity, and is more suitable for the dense mode, that is, multieast destination nodes are densely distributed in the area.
