| Abstract: | A multicast routing algorithm of multiple QoS constraints based on widest-bandwidth (MRQW) which takes available bandwidth as the prime metric, considering the constraints of the surplus energy of the node, delay and delay jitter, is presented. The process of routing based on MRQW is provided for as well. Correctness proof and the complexity analysis of the MRQW are also given in the paper. Simulation results show that the MRQW has a good performance in creating multicast trees. It not only satisfys multiple QoS constraints but also makes multicast links have larger available bandwidth |
| Keywords: | computer network Ad hoc networks QoS multicast routing available bandwidth |
