Simultaneous Handoff of Mobile-IPv4 and 802.11
Independent Consultant
This document describes a way to perform simultaneous Mobile-IPv4 handoff and 802.11 Access Point Association/Reassociation. Mobile-IPv4 Registration messages are carried as Information Elements in 802.11 frames. This way Mobile-IPv4 can perform handoff at the same time as 802.11 handoffs. The Foreign Agent can be a part of the Access Point or may serve a number of Access Points. The implications to existing mobility entities such as Access Point, Mobile Node, and Foreign Agent are disccussed. Also pointed out are potential issues with 802.1x and the emerging 802.11i standards.
