With the explosion of wireless technologies, variable types of mobility are presented. To provide seamless communication and mobility management, IP based mobility management protocols are proposed. One of them, to provide inter/intra/inner vehicle communication, the vehicles’ mobility management is studied that called VANET (vehicular ad hoc network). However, the mobility of vehicular results in short lived connections to access router (AR), affecting the availability of IP services in VANET. The most critical issue consists of the design of scalable routing algorithms that are robust to frequent path disruption caused by vehicles' mobility. With the navigation information that one of vehicles’ mobility features, we are classified into intra highway mobility and global mobility management mobility. Furthermore, we propose efficient mobility management scheme based on route prediction in VANET. Experimental analysis shows that proposed mobility management protocol reduces handoff latency, signaling costs and packet loss.
