Mobile IPv6 based Mobile Networks are becoming increasingly important with the widespread popularity of wireless internet connectivity. For large networks, an extension, namely, the Hierarchical Mobile IPv6 is used, which suffers from overloading of the Home Agent as every packet sent has to pass through it and this produces a significant loss in performance. In this paper, a method to improve the mobility using the fast handover of Mobile IPv6 (FMIPv6) and the Reverse Routing Header Protocol is proposed. Simulation results at different packet intervals show that, the proposed scheme is able to reduce the average delay and achieve an optimum level of throughput.
