Improved fast handover protocol using HMIPv6 based on IEEE 802.16e network

초록

Since the Wibro service realize mobile network on the public, it has been considered that it is not enough to support real time service at vehicular speed. The standard Fast Mobile IPv6 Handover Protocol using HMIPv6 may guarantee seamless service as long as the Mobile Node moves in the same domain MAP however it does not regard fast handover over inter-MAP domain. Thus Macro Mobility Handover in HMIPv6 was proposed to reduce handover latency in inter-MAP domain. But it is still not enough to support real-time service. So we propose an Improved FHMIPv6 over 802.16e network to reduce the overall handover latency. We embedded Layer 3 handover messages of the FHMIPvo6 into the Layer 2 handover messages. So the MN is able to finish overall handover procedure earlier in our scheme. The numerical results show the performance of IFHMIPv6 has improved 32% in comparison with FHMIPvo6. © Springer-Verlag Berlin Heidelberg 2007.
