Recent research in handover schemes for VANETs focuses on designing seamless, low-latency mobility management protocols that accommodate high vehicle speeds, frequent network transitions, and heterogeneous access technologies. Emerging solutions integrate mobile edge computing (MEC), software-defined networking (SDN), and multi-tier infrastructure (e.g., RSUs, cellular base stations, fog nodes) to proactively manage handovers, reduce packet loss, and maintain service continuity. For example, schemes that pre-cache data at MEC servers, utilize global network views via SDN controllers, and employ Layer-2 extensions to minimize Layer-3 re-configuration overhead have demonstrated significant improvements in throughput and reduced handover latency. There is also growing attention on secure handover architectures that incorporate multicast support, authentication, and blockchain frameworks to ensure uninterrupted connectivity while preserving privacy and trust in high-mobility vehicular environments.
