Abstract
Named Data Networking (NDN) is considered to be one of the most promising designs for the next generation of network architecture. Vehicles are typically interested in the content itself than the location of the host. Owing to the content-centric attributes, NDN can support highly dynamic topologies more than the traditional host-centric communication mode. So it will be widely used in vehicluar networks. The moving vehicles are constantly handover between different roadside units (RSU), which affects the backhaul of data packets and increases transmission delay. Therefore handover in Internet of Vehicles (IoV)-based NDN is a challenge to be solved. In order to improve communication quality, this paper proposes a pre-handover forwarding mechanism based on RSU level and content popularity by establishing a probability model. Routing data packets in advance by predicting whether the content requested by the vehicle is cached in the RSU after handover. Thus the mechanism not only reduces delay, but also solves the problem of packet loss caused by network topology changes. In addition, in order to further improve content retrieval efficiency and reduce delay, this paper also proposes a method based on the tabu search (TS) algorithm to quickly search for the target vehicle within the coverage of the RSU. Simulation results show that the mechanism proposed in this paper outperforms existing related mechanisms in terms of average delay and delivery rate.
