SRM (scalable reliable multicast) is a good example of a robust design intended to work across a wide range of group sizes and dynamics topologies, even though it does not address the integration of the multicast with the mechanisms supporting mobility. In this paper, we propose a reliable mobile multicast scheme called "Multi-Level Reliability Mobile Multicast Supporting SRM" (Scalable Reliable Multicast), MR MoM. MR MoM is designed to reasonably support SRM. The scheme consists of mobile multicast support without error recovery and multi-level reliability support. For our mobile multicast support, we adopt Mobile IP regional registration and low latency handoff in Mobile IPv4 to provide the efficient delivery of multicast packets to MH (mobile hosts), less frequent re-computation of the multicast trees and lower packet loss during handoff. For the multi-level reliability support, MR MoM is a receiver-based protocol in which the receivers themselves are responsible for loss detection and error recovery. In addition, original ADU (application data unit) naming is slightly modified to seamlessly cooperate with SRM. We have simulated our reliable mobile multicast protocol using the NS Network Simulator to compare our scheme to the reliable multicast protocol (RMMP). The performance results show that our proposed scheme is highly efficient. We also show the average number of requests and repairs, which show how scalable our scheme is.
