LT-TMAP fast handover scheme on improved HMIPv6

The rationality of MAP choice will touch the whole capability of network in Hierarchical Mobile IPv6. Aim at that, choose inconsequential MAP,it will increase service time-lag of the Mobility Node and the load of MAP is too convergent and so on. This paper proposes a LT-TMAP fast handover scheme on improved HMIPv6, describes the carry out process in theory. The emulational results show that this scheme could use MAP resources of the network more effectively. It improves the handover efficiency and possesses better Real-time.
