Abstract
Vehicular communication is an emergent technology with promising future, which can promote the development of mobile vehicular networks. Due to the broadcast nature of wireless channels, vehicular user mobility, and the diversity of vehicular network structures, the physical layer security issue of the mobile vehicular networks is a major concern. In this paper, the physical layer security performance of the mobile vehicular networks over N-Nakagami fading channels is investigated. Exact closed-form expressions for the probability of strictly positive secrecy capacity (SPSC), secrecy outage probability (SOP), and average secrecy capacity (ASC) are derived. Monte-Carlo simulation is used to verify the secrecy performance under different conditions. We further investigate the relationship between secrecy performance and the system parameters.
