Abstract

The development of wireless network technology and user demands for mobility support have motivated the IETF to introduce mobile IP, mobile IPv6, and its extension, the network mobility (NEMO) basic support protocol. In the NEMO environment, mobile networks form a nested structure. Nested mobile networks based on NEMO basic support (NBS) protocol have the pinball routing problem because packets are routed to all home agents of the mobile routers using nested tunnelling. In this paper, a route optimization scheme is proposed which uses the mobility anchor point employed in hierarchical mobile IPv6, and modifies the binding update messages to minimize overhead in route optimization. We evaluate route optimization cost in terms of delay. The results demonstrate a minimum performance improvement of 30% and even shorter routing delay than NBS in non-optimized cases.
