N2 - This paper investigates the issues of QoS multicast routing in wireless ad hoc networks. Due to limited bandwidth of wireless nodes, a QoS multicast call will be blocked if there does not exist a single multicast tree that has the requested bandwidth, even though there is enough bandwidth in the system to support the call. We propose a new QoS multicast routing scheme that uses multiple trees. The aggregate bandwidth of multiple trees can meet the band-width requirement and the delay from the source to the farthest destination node shall not exceed a pre-specified bound. Two strategies for constructing multiple trees are studied. The simulation results show that the new scheme significantly improves the request success rate and makes a better use of network resources. © Springer-Verlag Berlin Heidelberg 2006.
