The FTHMRP protocol for Multicasting in Mobile Adhoc Networks- A Review

In mobile adhoc network multicasting is identified as one of the major area of research. FTHMRP is multicasting protocol which basically resolves the problem of initially conventional flat multicasting protocol. Conventional flat multicasting protocol does not scale well to network size and are not suitable for tam multicasting in large scale mobile adhoc network. To overcome these all problems like large membership as well as network size and fault tolerance to link failures, one protocol introduced called FTHMRP. The FTHMRP protocol, which uses the hierarchal routing in hyper cubic architecture for multicasting tree generation. The outcome of proposed algorithm of FTHMRP is very good in term of fault tolerance. This protocol can solve the problem of link failure and fault tolerances. FTHMRP used the hierarchical routing for multicast tree generation in hyper cubic architecture. But when mobile nodes multicasting the RREQ packet to make path at that time it increase the energy consumption in the network. So using unicast forwarded multi-source multicast routing protocol this problem may be resolved.
