Abstract

Multicast for ad hoc networks becomes popular. However, along with increase of the network size and node mobility, it is difficult to design the multicast routing for large ad hoc networks with high mobility. In order to cope with this difficulty, this paper proposes a new hierarchical multicast routing for such ad hoc networks. The characteristics of the proposed scheme are introduction of the inter-cluster group mesh in the autonomous clustering. The states of clusters are changed according to join and leave of multicast members and the group mesh among clusters is dynamically constructed. The simulation results show that the proposed scheme is scalable for the network size and adaptable to node mobility.
