Data Forwarding Scheme for Vehicle Tracking in Named Data Networking

What is it about?

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 to Consumer mobility in NDN-based VANETs, this article proposes a novel vehicle tracking-based Data packet forwarding scheme (VTDF) to improve the successful delivery rate of Data packets in mobile environments. In this approach, the urban road structure is divided into complex multi-junction and straight lane scenarios and Data packets 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 for consumers compared to the standard methods.

Why is it important?

In this paper, we proposed a vehicle tracking-based data forwarding method for efficient Consumer mobile support in NDN-based VANETs. The method of forwarding Data packets along the direction of motion of the Consumer was adopted, a TNS and QHM were utilized to reduce the communication interruptions caused by user migration as well as the network overhead, and a popular caching approach was used to reduce data retrieval latency. We firstly analyzed the effects of the TNS and QHM on the performance of VTDF, then investigated the network delay, handover delay, and data delivery rate of VTDF and other mobility solutions. The simulation results showed that the VTDF scheme performs better than other mobile support methods. In future research, we will further study the datatransmission rules in the case in which both the requester and publisher move and reduce the network consumption as much as possible in the combined V2R and V2V communication mode to improve the network transmission performance.
