Global mobility and Handover management for heterogeneous network in vanet

Internet services. The access is provided by Internet gateways located on the site of roadside. However, the Internet integration requires a respective mobility support of the vehicular ad hoc network. In this paper we will study about the network mobility approach in vehicular ad hoc network; the model will describe the movement of vehicles from one network to other network. The proposed handover scheme reduces the handover latency, packet loss signaling overhead.
