With the continuous development of millimeter-wave communication technology, new requirements such as ultra-reliability and higher data rates pose challenges to security issues traditional cryptographic encryption in vehicular ad hoc networks (VANET). Physical layer uses characteristics different wireless channels protect information security. In this paper, we propose a novel VANET routing mechanism that utilizes physical improve secrecy performance, which is compatible with network. Specifically, design secure selection factor, utility function, takes into account effects both rate single-hop transmission distance achieve hop selection. addition, waiting based on function. Compared algorithms, greedy perimeter stateless (GPSR) Dijkstra simulation results illustrate our achieves superior performance dynamic adaptability.
