Many network applications require transmitting the same single copy of data packets concurrently to many destinations. Applying the infrastructure-based multicast routing protocols in Mobile Ad hoc wireless NETworks (MANETs) is a big challenge. Factors that make Multicasting in ad hoc networks is more complex than in wired networks are host mobility, Interference of wireless signal and broadcast nature of the communication. Tree based protocols are not suitable for dynamic topology scenarios due to frequent overhead updation, isolation and partition problems. The major cause of difficulty in routing for multi-hop MANETs comes from node mobility, as performance is vulnerable to changes in network topology.
