Fast Mobility Management for Delay-Sensitive Applications in Vehicular Networks

Abstract—This letter presents a fast IP mobility management scheme in vehicular networks where multiple wireless network interfaces are used to perform the fast handover without packet loss. In order to do that, the IETF standard HMIPv6 has been extended, where multiple simultaneous tunnels between the HMIPv6 MAP and the mobile gateway are dynamically constructed. The architecture for supporting multiple tunnels has been designed, and both mathematical analysis and simulation have been done for performance evaluation. Index Terms—HMIPv6, mobility management, handover with dual interfaces. I
