An active network based hierarchical mobile Internet protocol version 6 framework

The mobile Internet protocol version 6 (MIPv6), based on IPv6, will be widely used in the next generation wireless network. The latency of the handover is one of the most important parameters in evaluating MIPv6. At present, the popular wireless handover technologies include the fast mobile Internet protocol version 6 (FMIPv6) and the hierarchical mobile IPv6 (HMIPv6) invented by IETF and the active network invented by DARPA. In this paper, we propose a new strategy of the wireless handover in MIPv6, which is based on the HMIPv6 and the active network. The strategy will optimize the handover process during MN´s roaming. In the network simulator (NS-2), we set up a simulation scenario. We compare the handover performance of the network architecture using our strategy with that of HMIPv6 and prove that our strategy has better performance.
