A Pmipv6-Fog Scheme for Vehicular Mobility Support

Vehicular Ad-hoc Networks (VANETs) and the rapid development of communicationand computation technologies are one of the main next generation wireless networks which are envisaged to be an integration of homogeneous and heterogeneous wireless networks. Although VANETs are deployed in reality offering several services, a seamless handover mechanism with negligible handover delay is required to maintain active connections during roaming across these networks. Cloud computing as a solution has been deployed with special requirements of mobility, location awareness, and low latency. However, the handover delay remains high and unacceptable for delay-sensitive services such as real-time and multimedia services. This paper, therefore, proposes a PMIPv6-Fog model for VANET mobility management framework utilizing the merging of VANETs with fog computing, and the recently emerged network-based localized mobility management protocol, Proxy Mobile IPv6, to further reduce handover delay.
