Named data networking (NDN) is one representation and implementation of information-centric networking (ICN) and is considered to be among the most promising designs for the next generation of network architecture. The introduction of NDN into vehicular ad-hoc networks (VANETs) and utilization of its content-centric characteristic to improve data transmission and distribution in VANETs has become a research hotspot in recent years. However, research on mobility support of NDN-based VANETs still faces many challenges. To solve the issue of data transmission path breaking due toConsumermobility in NDN-based VANETs, this article proposes a novel vehicle tracking-basedDatapacket forwarding scheme (VTDF) to improve the successful delivery rate ofDatapackets in mobile environments. In this approach, the urban road structure is divided into complex multi-junction and straight lane scenarios andDatapackets are forwarded according to vehicle movement information. Simulations indicated that this vehicle tracking scheme provides a lower average data transmission delay, shorter handover delay between roadside units, and higher data delivery rate forConsumerscompared to the standard methods.
