Multicasting can be efficiently supported a variety of applications that are characterized by a close degree of collaboration, typical for
many ad-hoc applications currently envisioned. Within the wired network, well-established routing protocols exist to offer an efficient
multicasting service. As nodes become increasingly mobile, these protocols need to evolve to similarly provide an efficient service in new
environment. This paper discusses the performance of two proposed multicast protocols for adhoc networks: ODMRP and AMRoute. AMRoute
as logical core and are responsible for initiating and managing the signaling component of AMRoute such as detection of group members and
tree setup. Logical cores differ significantly from those in CBT and PIM-SM, since they are not a central point for data distribution and can
migrate dynamically among number of nodes. Simulation results (using NS-2) specify that AMRoute signaling traffic remains at relatively low
level for typical group sizes. ODMRP maintains mesh based on softstate. The results show that in many scenarios ODMRP achieves a higher
packet delivery ratio, but results in much higher overheads.
