Handover performance analysis of distributed mobility management in vehicular networks

The provision of seamless mobility is crucial for an efficient support of global roaming in vehicular networks. The most compatible and interoperable handover management solutions are designed based on IP mobility protocols. Current IP mobility management protocols, including Proxy Mobile IPv6 (PMIPv6), rely on centralized and static mobility anchor, which intrinsically pose enormous burdens on the central anchors in terms of user mobility management and connectivity needs. Recently, network-based Distributed Mobility Management (DMM) based on PMIPv6 has been proposed to overcome the aforementioned issues. In this paper, we study the worth of adopting network-based in vehicular networks. We analyze and compare the handover performance of network-based DMM with PMIPv6. For handover analysis, the effect of system parameters, such as vehicle velocity, radius of cells, and network scale are investigated with respect to handover latency and packet loss metrics. Numerical results show that network-based DMM outperforms PMIPv6.
