Abstract: A path node-driven strategy based one-to-many multicast routing algorithm in green Internet (GIOMR) is proposed to generate a low-power shortest path tree, fully making use of the path node sharing paths and meanwhile improving user’s QoS satisfaction degree. The GIOMR is implemented over CERNET2 topology by simulation. It has been shown that GIOMR has better performance on the network power consumption, the success rate of routing and the running time than efficient heuristics for energy-aware routing (EHER) algorithm.
