Description: There are increasing interest and big challenge in
designing a scalable and robust multicast routing protocol in
a mobile ad hoc network (MANET) due to the difficulty in
group membership management, multicast packet forwarding
and the maintenance of multicast structure over the dynamic
network topology for a large group size or network size. In
this paper, we propose a novel Robust and Scalable Geographic
Multicast Protocol (RSGM). Several virtual architectures are used
in the protocol without need of maintaining state information for
more robust and scalable membership management and packet
forwarding in the presence of high network dynamics due to
unstable wireless channels and node movements.
