Abstract

In the European Telecommunication Standards Institute (ETSI) framework, the vehicle-to-vehicle (V2V) and the vehicle-to-roadside (V2R) communications on the 5 GHz frequency band must use the decentralised congestion control (DCC) algorithm standardised by the ETSI. The DCC algorithm distinguishes itself from other methods in that it simultaneously regulates no less than four parameters that all work to the identical effects. However, it is have claimed that this apparently reassuring feature is actually excessive and can lead DCC to perform sub-optimally. It is shown that it could be simplified to use fewer parameters by demonstrating that a physical layer data rate control, which is only one of the four used by the DCC, achieves a better result.
