Performance Analysis of an Efficient Multicast Scheme for the Multimedia Communications in NEMO

Multicast can be considered as an efficient computing service for sharing resources in the multimedia communication systems. Sharing communications are not easy to do in the mobility networks (MONETs) for the limited bandwidth and the overhead of tunneling. Multicast is an intuitive method to solve this problem. To improve the performance, the multicast topology should be redesigned for the MONETs. The Mobile Router Forwarding Scheme (MRFS) algorithm is proposed for this goal. Compare with other schemes we surveyed, we can find that MRFS can reduce the storage cost for every Mobile Router (MR) especially in the TLMR (Top level MR) for the tree topology of NEMO. We also analyzed the performance of MRFS with the numerical approach and the simulation tool - network simulator version 2 (NS2). The results show that MRFS algorithm outperforms other multicast protocols. To show the performance of the proposed schemes, we design a lot of experiments to analyze the performance. The experiment analysis could be an analysis model for the complex system which is not easy to be analyzed by the mathematic model.
