DOI: https://doi.org/Vehicular Ad Hoc Networks (VANETs) have become an integral component in enabling dynamic communication among military vehicles in battlefield environments. However, ensuring secure and efficient data transmission in such highly mobile and critical scenarios remains a significant challenge. This paper proposes an Enhanced Weight-Based Clustering Algorithm (EWBCA) specifically designed for military VANETs to facilitate stable communication and robust security. The algorithm employs multiple weighted parameters, including node mobility, transmission range, residual energy, and trust value, to determine optimal cluster heads, enhancing cluster stability and data integrity.The EWBCA framework integrates secure routing mechanisms and adaptive cluster maintenance to prevent frequent re-clustering and malicious node entry. Additionally, a lightweight encryption layer is embedded within the data exchange module to ensure secure communication between cluster nodes and heads. Performance metrics such as packet delivery ratio, end-to-end delay, cluster stability, and security throughput were evaluated using NS-3 simulation. The outcomes of the research workexhibit that EWBCA outperforms accessible clustering approaches in stipulations of stability, security, along with communication efficiency, particularly in hostile and fast-changing military environments. This study contributes a significant step towards building secure, reliable, and energy-efficient VANET architectures tailored for military vehicular networks.
