Summary
This paper addresses the limitations of the current TCP/IP architecture in supporting connected vehicle communications, specifically regarding mobility, latency, and quality of service. Motivated by the need to enhance road safety through Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) interactions, the authors evaluate Named Data Networking (NDN) as a promising alternative. NDN is an information-centric architecture that routes data based on content names rather than host addresses, featuring in-network caching that allows vehicles to serve requests from cached data even when original producers are unavailable. The study aims to demonstrate whether NDN’s inherent features, such as adaptive forwarding and built-in security, offer superior performance compared to traditional IP-based protocols in dynamic vehicular environments. To evaluate these architectures, the authors conducted a simulation study using ndnSIM, an ns-3-based simulator, combined with SUMO for traffic generation. The experimental design simulated an urban scenario in Kenitra, Morocco, involving 66 vehicles moving at 20 m/s. The network consisted of 12 producer vehicles and 54 consumer vehicles, with consumers generating Interest packets at a rate of 10 per second. The simulation lasted 30 seconds and utilized IEEE 802.11p for the MAC layer. Key parameters included a data payload size of 1200 bytes, a Least Recently Used (LRU) cache replacement policy, and a maximum Content Store size of 1000 entries. The study compared the performance of NDN against TCP/IP across metrics including throughput, packet delay, and packet delivery success rates. The results indicate that NDN significantly outperforms TCP/IP in vehicular networks. In terms of throughput, NDN demonstrated a higher average throughput that increased over time, whereas TCP/IP throughput started higher but declined as the simulation progressed. Regarding latency, NDN reduced the average packet delay to nearly zero microseconds, leveraging its caching mechanism to satisfy requests locally without contacting distant producers. In contrast, TCP/IP delays increased over time. Furthermore, NDN achieved a null data drop rate, with almost all sent packets successfully received by consumers throughout the simulation. TCP/IP, however, experienced increasing packet loss as time elapsed, with successful delivery limited primarily to the beginning of the simulation. The authors conclude that NDN is a more suitable architecture for connected vehicles than TCP/IP, offering lower latency, higher throughput, and improved reliability due to its content-centric routing and in-network caching capabilities. These findings suggest that NDN can effectively support the high mobility and intermittent connectivity characteristic of vehicular networks, potentially contributing to safer and more efficient intelligent transportation systems. The paper identifies NDN as a viable future standard for vehicular communications and proposes future work focused on enhancing security mechanisms within NDN-based vehicular networks.
