A vehicle today needs Internet connectivity which consists of many mobility based devices, built in computers, and various devices carried on by the passengers. These devices are connected to the Internet to provide entertainment to passengers, to execute some official works and to provide connectivity to its base network too. Through Network Mobility (NEMO) by IETF, connectivity can be provided. Some times the movable networks may work based on nesting concept also, during that scenario the regular limitation like Sub-optimality due to additional packet size and packet counts are increasing. In order to overcome the additional limitation due to nested network mobility, we are proposing a new mechanism to avoid the additional nesting to reduce the same additional packet size and delays. © 2012 Springer-Verlag.
