A Novel Intra-Domain Continues Handover Solution for Inter-Domain Pmipv6 Based Vehicular Network

Abstract

Abstract-IP mobility management protocols (e.g. host based mobility protocols) incur significant handover latency, thus aggravate QoS for end user devices. Proxy Mobile IPv6 (PMIPv6) was proposed by the Internet Engineering Task Force (IETF) as a new network-based mobility protocol to reduce the host based handover latency. However the current PMIPv6 cannot support the vehicles high mobility while the vehicles motion within PMIPv6 domain. In this paper we introduce a novel intra-domain PMIPv6 handover technique based vehicular network using Media Independent Handover (MIH). The novel intra-domain PMIPv6 handover based vehicular network improves the handover performance of PMIPv6 by allowing the new PMIPv6 domain to obtain the MIIS information to estimate whether the handover is necessary or not before the vehicles movement to the second MAG of the new PMIPv6 domain. We evaluate the handover latency and data packet loss of the proposed handover process compared to PMIPv6. The conducted analysis results confirm that the novel handover process yields the reduced handover latency compared to that of PMIPv6 and also prevents data packet loss.
