Abstract |
In this paper, a new scheme is proposed to allow the correspondent node to recognize the handover situation of the mobile node for vertical handovers using Mobile IPv6 signaling. The proposed scheme might be helpful for quick adjusting real-time traffics between two nodes when a drastic change in a bandwidth occurs due to vertical handovers in heterogeneous access networks that have a quite different capacity and coverage. Firstly, this paper defines newly the care-of address configuration specified by the new link of the mobile node in Mobile IPv6. Secondly, this paper gives a new method for the correspondent node to recognize the handover situation of the mobile node using the return routability procedure with the link specified care-of address in the network layer. A guideline for the congestion control is provided for improving TCP performance during vertical handover. Finally, the analytical result shows the CN recognizes more quickly the MN’s handover situation than the existing scheme. |
