To support seamless handover at realtime applications, IETF fast handover scheme was proposed in wireless IP networks by minimizing handover latency. However, when a correspondent node sends packets to the mobile node during the handover period, inefficient routing occurs in hierarchical Mobile IPv6 networks. In this paper, we propose a novel fast handover scheme to minimize the handover latency. In our proposal, a mobile node sends a fast binding update messages to the mobility anchor point instead of the old access router. Thus, our proposal can reduce the handover latency incurred by inefficient routing from old access router to new access router. In addition, our proposal can reduce the duplicate address detection handling time during the handover by maintaining a list of the confirmed new care-of-address beforehand. Analysis results using the discrete analytic model shows that our proposal can have superior performance than existing handover scheme when packet arrival rate and L2 layer switching time are high. © Springer-Verlag Berlin Heidelberg 2004.
