However in nested mobile networks NEMO suffers from the pinball routing problem which results in long packet transmission delays. To solve the problem we propose a domain-based route optimization DRO scheme that incorporates a domain-based network architecture and ad hoc routing protocols for route optimization. DRO also improves the intra-domain handoff performance reduces the convergence time during route optimization and avoids the out-of-sequence packet problem. A detailed performance analysis and simulations were conducted to evaluate the scheme. The results demonstrate that DRO outperforms existing mechanisms in terms of packet transmission delay . better route-optimization intra-domain handoff latency convergence time and packet tunneling overhead.

Introduction Recently vehicular networks have received a significant amount of attention in the field of wireless mobile networking. On public methods of transportation such as taxies trains buses and airplanes many mobile network nodes MNNs move together as a large-scale vehicular network. In such environments people can use mobile devices for accessing services such as VoIP video conferencing web-browsing and music downloading any-time-anywhere. With the emergence of vehicular networks users require seamless and efficient communications on the move. Therefore developing a route optimization scheme has become an imp ortant .
