on-demand protocols and construct a shared delivery tree to support
multiple senders and receivers within a multicast session.
e topology of a wireless mobile network can be very dynamic,
and hence the maintenance of a connected multicast routing tree may
cause large overheads. To avoid this, a different approach based on
meshes has been proposed. Meshes are more suitable for dynamic
environments because they support more connectivity than trees;
thus, they support multicast trees. ere are two types of mesh-based
multicast routing protocols included: core-assisted mesh protocol
(CAMP) and the on-demand multicast routing protocol (ODMRP).
ese protocols build routing meshes to disseminate multicast packets
within groups. e d ...
