The Mobile Router Forwarding Scheme for Multicast in the NEMO

Multicast is an efficient method to transmit datagrams in the Internet. In this paper, we provide a multicast algorithm in a network mobility (NEMO) environment. We propose the mobile router forwarding scheme (MRFS) algorithm. There are two advantages in the MRFS algorithm. First, MRFS reduces the storages in every MR especially in the TLMR (top level MR). Second, MRFS transmits multicast datagrams more efficiently that because MRFS transmit multicast datagrams not only by TLMR but also by every MR. The above of two advantages are achieved using MRFS tables. In this paper, MRFS algorithm is analyzed. MRFS algorithm is more efficient than other multicast protocols in the NEMO according to the evaluation.
