Transmission Power-Control Certificate Omission in Vehicular Ad Hoc Networks

In this paper, we propose a Transmission Power-control Certificate Omission scheme, which seeks to achieve a better balance between the number of incurred cryptographic packet loss (CPL) and network packet loss (NPL) to maximize vehicle cooperative awareness even under dense traffic conditions. Unlike previously proposed schemes, we efficiently control channel load by adopting a congestion detection and congestion control algorithm in our scheme. The simulation results indicate that our proposed scheme can achieve a better balance between the number of incurred CPL and NPL and can maximize vehicle cooperative awareness even under dense traffic conditions.
