Proactive Hand-Off Target Orientation Cache in Fast Handover for Mobile IPv6

In order to efficiently utilize wireless environment network resources. Fast handover for mobile IPv6 (F-M/Pv6) technology is currently being considered. It is necessary for access routers to exchange information with their neighbors. However, this method is outside the scope of the F-MIPv6 Internet draft. In this article, we propose an approach to assist F-MIPv6 in obtaining IP addresses for subnet candidates from layer 2 information. The proposed proactive hand-off target orientation (PHOTO) provides a realistic geographical relation without using wireless location technology. We demonstrate that PHOTO helps F-MIPv6 to overcome its´ inability to obtain IP addresses immediately through the access point MAC address
