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).

VANETs are one of the main next generation wireless networks which are envisaged to be an integration of homogeneous and heterogeneous wireless networks. The inter-networking of these wireless networks with the Internet will provide ubiquitous access to roaming network users. However, a seamless handover mechanism with negligible handover delay is required to maintain active connections during roaming across these networks. Several solutions, mainly involving host-based localized mobility management schemes, have been widely proposed to reduce handover delay among homogeneous and heterogeneous wireless networks. However, the handover delay remains high and unacceptable for delay-sensitive services such as real-time and multimedia services. Moreover, these services will be very common in next generation wireless networks. Unfortunately, these widely proposed host-based localized mobility management schemes involve the vehicle in mobility-related signaling hence effectively increasing the handover delay. Furthermore, these schemes do not properly address the advanced handover scenarios envisaged in future wireless networks. This paper, therefore, proposes a Logical Cross-Layer Optimization Block for VANET vertical mobility management framework utilizing cross-layer design, the IEEE 802.21 future www.macrothink.org/npa 1 Network Protocols and Algorithms ISSN 1943-3581 2015 standard, and the recently emerged network-based localized mobility management protocol, Proxy Mobile IPv6, to further reduce handover delay.
