Abstract

The PMIPv6 (proxy mobile IPv6) protocol provides local mobility to a mobile node without requiring any modification of the mobile node. A PMIPv6 domain contains multiple MAGs (mobility access gateway), and they advertise the same prefix to the mobile node so that the mobile node feels like it is always on the same link. However, horizontal/vertical handover still happens while the mobile node moves among MAGs in the PMIPv6 domain, and this handover could cause undesirable delay to the mobile nodes running real time applications like VoIP. To solve this problem, this paper proposes a fast handover scheme for the PMIPv6 based on 802.11 networks. This scheme uses IAPP (inter-access point protocol) to transfer context information such as the mobile node´s authentication information and HNP (home network prefix).
