Abstract

Mobile IP (MIP) is designed for supporting mobile nodes. However, the technology does not sufficiently handle NEtwork MObility (NEMO). The NEMO Basic Support (NBS) [1] ensures session continuity for all the nodes in a MObile NETwork (MONET). Since the protocol is based on MIP, when used to support multicast for NEMO, it inherits the same fundamental problems as MIP, such as tunnel convergence. Recently, many Route Optimization (RO) schemes have been proposed for the pinball routing problem in NEMO. And we should use the RO schemes for multicasting in NEMO. However, the tunnel convergence problem may be remained as unsolvable problem. Hence, we propose the similar source-based routing multicast scheme. In this paper, we present the multicast scheme based on well-known RO scheme Path Control Header (PCH) [2] in NEMO environments. Furthermore, the proposed scheme's recovery time is more efficient than other well-known multicast schemes.
