Abstract

Abstract

Objective Vehicle-infrastructure cooperative networks (V2X) are characterized by environmental openness, large node counts, high node mobility, frequent changes in network topology, unstable wireless channels, and diverse service requirements. These technical features present significant challenges to the efficient transmission of data. Thus, rapid network reconfiguration based on different service requirements becomes crucial, and constructing a flexible real-time network is essential for the application of V2X technologies in intelligent transportation systems (ITS). With the rise of programmable network technologies, programmable data plane techniques are driving a shift from “rigid architectures” to “flexible, adaptive” systems, enhancing the flexibility of intelligent transportation networks. In this context, a network protocol standard based on geospatial location information is proposed. Combining this standard with a polymorphic network architecture, a geospatial identifier network modal is designed. In this modal, the traditional three-layer protocol is replaced by packets containing geographic location identifiers, enabling packet forwarding directly based on geographic location information. Addressing and routing based on geographic location are more efficient and convenient than traditional IP-based addressing and routing. Furthermore, a geospatial identifier-based vehicle-infrastructure cooperative traffic system is designed for intelligent transportation scenarios. This system supports direct forwarding of packets based on geographic location information, offering flexibility in supporting the dissemination of road safety and traffic information within the V2X system, ensuring vehicle safety and improving route planning efficiency. Methods Based on the network protocol standard for geospatial location information and the flexible and scalable architecture of polymorphic networks, a geospatial identifier network modal is proposed. This modal replaces IP with a geospatial identifier network protocol at the three-layer network layer and implements addressing and routing based on geospatial information on programmable polymorphic network elements. To achieve end-to-end transmission, a geospatial identifier network modal protocol stack is designed, effectively supporting the unified transmission of various network modals. Additionally, considering the service demands and transmission characteristics of the GEO network modal, we develop a dynamic geographic routing mechanism. This mechanism operates within a multimodal network controller and leverages the relatively stable coverage areas of roadside base stations to establish a two-level mapping: "geographic region - base station/geographic coordinates - terminal". This enables precise end-to-end path matching for GEO network modal packets, achieving flexible and centrally controlled geographic forwarding. To validate the usability of the geospatial identifier network modal, a vehicle-infrastructure cooperative intelligent transportation system that supports the geospatial identifier addressing mechanism is developed, effectively facilitating the dissemination of road safety and traffic information. A detailed analysis of the business functional requirements of the intelligent transportation system is conducted, followed by the design of the business processing flow and the overall system. Additionally, key hardware and software modules, including geospatial representation data plane code, traffic control center services, road test base stations, and vehicle terminals, are designed and their implementation logic is provided. Results and Discussions System evaluation includes four main aspects: system evaluation environment, system operational effectiveness, theoretical analysis and performance evaluation. As shown in Figure 7 and 8, a prototype intelligent transportation system is deployed. The system is tested and validated to ensure it can transmit messages according to the geospatial identifier modal. Taking a typical V2V communication scenario as an example (e.g., onboard terminal T₃ sending a road condition alert M to T₂), we use sequence analysis to compare the forwarding efficiency of the GEO network modal against traditional IP protocols. Theoretical analysis demonstrates that the GEO network modal offers significant technical advantages in forwarding efficiency, as illustrated in Figure 9. Further tests are conducted by varying conditions such as the number of terminals (Figure 10), background traffic (Figure 11), and transmission bandwidth (Figure 12) to assess the changes in transmission performance of geospatially represented modal packets. The network modal transmission performance of the intelligent transportation system is analyzed. System performance evaluation experiments demonstrate that the system exhibits good stability and high efficiency, meeting the demands of typical V2X traffic scenarios, such as massive connectivity and elastic traffic flows. Conclusions Combining the flexible and scalable architecture of polymorphic networks with the network protocol standard for geospatial location information, the geospatial identifier network modal is proposed and successfully implemented, enabling direct packet forwarding based on geospatial location. Additionally, for intelligent transportation scenarios, a prototype vehicle-infrastructure cooperative intelligent transportation system based on geospatial identifier addressing is designed. This system supports a variety of applications within the V2X context, such as road safety alerts and traffic information broadcasting. The intelligent transportation system ensures vehicle safety and enhances route planning efficiency. Experimental results show that the system provides excellent stability and efficiency, effectively supporting typical traffic scenarios involving massive connectivity, network background traffic fluctuations, and elastic service traffic. As vehicular network technologies continue to evolve, this system is expected to play a significant role in broader intelligent transportation fields, providing strong support for the development of safer and more efficient smart transportation systems.
