A Review Paper on Different Mobility and Handover Management Techniques in VANET

In this paper, the study focuses on the various mobility and handover management schemes for different networks (like heterogeneous/homogeneous networks) in Vehicular Ad hoc Network (VANET). Internet Engineering Task force (IETF) purposed MIPv4/v6 (Mobile Internet Protocol-version4/6) and its enhancements like HMIPv6 (Hierarichal), FMIPv6 (Fast), FHMIPv6, PMIPv6 (Proxy) are various mobility management techniques. A global mobility and handover management scheme is studied considering heterogeneous network in VANET. SIGMA (Seamless IP Diversity Based Generalised Mobility Architecture) provides a seamless handover to a mobile host. MMIP6, a scheme which integrate multihop IPv6 VANET in internet is analysed. A new scheme having Virtual Map (VMAP) to HMIPv6, another EAR-FMIPv6 (Enhanced Access Router) and also Media Independent Handover (MIH) supplied FMIPv6 schemes makes an optimised handoff. A scheme for supporting multimedia services, another scheme using VMAP to HMIPv6 and Simple Mobility Management Protocol (SMMP) uses a separate location management function provide a seamless handover.
