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.

Key words:

computer network, Ad hoc networks, QoS multicast routing, available bandwidth
