Inter-domain Proxy Mobile IPv6 based Vehicular Network

Proxy Mobile IPv6 (PMIPv6) was standardized by the Internet Engineering Task Force (IETF) NetLMM WG as a Network-based Mobility management protocol. This protocol allows the Mobile Node (MN) to maintain service connectivity while moving within the PMIPv6 domain. PMIPv6 mobility management is different from the Host-based Mobility management protocols; where the mobility signaling management is controlled by the serving network on behalf of the MN. PMIPv6 introduced new network entities to handle the signaling on behalf of the MN. However, PMIPv6 protocol can only manage the MN’s reachability within a local domain (intra-domain). If the MN moves beyond the perimeter of PMIPv6 domain, the mobility support will be lost. Thus, it is an imperative need to develop PMIPv6 to support interconnecting neighboring domains, which provide MN continuous support across domains. We propose an inter-domain handover scheme to reduce the handover latency in vehicular environment. The proposed scheme utilizes the Media Independent Information Service (MIIS) to help the vehicle store information about the network that it is attached with. Furthermore, the Local Mobile Anchor (LMA) will use Fully Qualified Domain Name (FQDN).
