A BiLSTM-integrated WAVE protocol for optimizing communication in high-density Vehicular networks using Dynamic Priority management

Abstract

This article presents a modified WAVE protocol optimized for vehicular ad hoc networks (VANETs), integrating a BiLSTM-based model for dynamic message priority estimation. The proposed method addresses the challenges of ensuring timely and reliable communication in highly dynamic network environments. By accurately assessing message priorities and adapting to varying network conditions, the protocol significantly reduces end-to-end delays, improves Packet Delivery Ratio (PDR), and maintains high throughput while minimizing routing overhead. Our analysis across different node densities and message priority loads demonstrates the protocol’s robustness and scalability, achieving superior performance in handling high-priority traffic. The results highlight the protocol’s effectiveness in real-time, safety-critical applications, such as collision avoidance and traffic management. The modified WAVE protocol, with its advanced priority estimation and resource management capabilities, offers a promising solution for enhancing communication efficiency in complex vehicular networks.
