Hybrid Routing and Security Framework for High Speed Vehicular Networks based on BESO Algorithm

The VANET architecture is highly dynamic due to the constant movement of vehicles, which complicates routing and data scheduling for high-speed communication. Incorporating security measures further adds to the complexity, often leading to increased delays and decreased throughput. To tackle these challenges, the proposed system focuses on reducing the overhead of key generation and utilizes a fog computing platform combined with lightweight encryption techniques. Specifically, the Batched Eagle Spotting Optimizer (BESO) algorithm is employed for efficient route selection, optimizing parameters like packet transmission timing and hash-based key creation. For security, a lightweight encryption method called ROTR is used, enabling faster data transmission by generating smaller keys. Overall, the integrated BESO-ROTR approach enhances routing efficiency and security while minimizing processing delays, with performance validated through metrics such as packet loss, transmission success, and throughput in high-mobility VANET environments.
