In this paper, the study focuses on the many handover methods 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 improvements like HMIPv6 (Hierarchal), FMIPv6 (Fast), FHMIPv6, PMIPv6 (Proxy) are various mobility management methods. A handover management scheme is studied considering heterogeneous network in VANET. SIGMA (Seamless IP diversity based Generalized Mobility Architecture) delivers a seamless handover to mobile host. MMIP6, a scheme which integrate multihop IPv6 VANET in internet is examined.
