Multicast routing is used for group communication. In multicasting, one sender sends data to multiple recipients, but sends only a single copy. Multicasting is more efficient than broadcasting, because broadcast packets have to be received by everyone on the local link. In this paper, a detailed study has been outlined regarding which protocol of Centralized Multicast (CM), Protocol Independent Multicast - Dense Mode (PIM-DM), Protocol Independent Multicast - Sparse Mode (PIM-SM) is the most efficient. The parameter for efficiency is minimizing the end-to-end delay. These protocols have been simulated by building different configurations in TCL scripts and running them in the NS2 network simulator. A comparison of average end-to-end delay is calculated from the simulations.
