摘要

Recent developments in Vehicular Ad hoc Networks (VANETs) pose new challenges for vehicular communication systems. This paper introduces an innovative framework that significantly improves safety, efficiency, and privacy in VANETs. This framework uses dynamic network management, efficient privacy-preserving techniques, and novel services such as speed limit alerts and SOS messages. These services not only enable the efficient operation of VANETs but also improve driver awareness and traffic safety. The proposed scheme will use an elastic network topology that dynamically adapts to the vehicles’ environment, thereby providing flawless communication and exceptional network performance. The simulation results demonstrate a network latency of 20 ms, a data throughput of 95%, and a packet delivery ratio of 98%, representing improvements of 60%, 19%, and 9% respectively over traditional VANET protocols, through the integration of Zero-Knowledge Proof authentication, blockchain-based dynamic network management, and TDMA-prioritized real-time safety alert dissemination. Additionally, the scheme will ensure the preservation of privacy in cars by using complex cryptographic techniques to enable the exchange of required information among vehicles. Finally, the speed limit alerts, acting as SOS messages, will be executed at each network node and alert drivers to speed limits and potential dangers in the surrounding environment. Additionally, dynamic network management will be employed, leveraging blockchain technology to create an immutable record of network operations and eliminate network failures.
