A Sensitive Metric for the Assessment of Vehicular Communication Applications

The technical evaluation of Vehicle-2-X communication properties in the field operational test simTD delivered first results. However, the need for new metrics arose to be able to measure the influences of communication characteristics on the application performance more precisely. Hence, we proposed the Consecutive CAM Period (CCP) as a suitable metric. In this paper we discuss the advantages of using the CCP compared to the classical communication metrics as the Packet Delivery Ratio (PDR). In a short evaluation study we furthermore present a method that helps to approach two issues. 1) The time and space dependent nature of the CCP facilitates to detect if use cases actually exist or not. 2) Particularly, the evaluation of the maximum CCP guaranties that certain situations are not missed compared to the usage of metrics with an arithmetic mean calculation.
