Mpls-Based Micro-Mobility Architecture for 5g Vehicular Visible Light Communication Networks

摘要

Future vehicular networks in the emerging era of 5G will be characterized by ubiquitous connectivity across heterogeneous networks (HetNets) while maintaining their required Quality of Service (QoS). 5G will introduce numerous small cells, implementing extreme densification, in order to increase capacity. In the context of vehicular networks, this translates to multiple handoffs occurring within seconds. It is critical that an efficient mobility management solution is devised for 5G vehicular networks to maintain seamless connectivity. In this paper, we investigate the use of Multiprotocol Label Switching (MPLS) based micro-mobility management to 5G vehicular visible light communication networks. MPLS has the advantage of fast and efficient packet forwarding. This paper proposes a hierarchical Integrated Services based MPLS architecture to overcome the limitations found in existing MPLS based micro-mobility schemes in terms of handoff latency, registration cost and explicit QoS support necessary for 5G vehicular communication networks.
