While this is surely beneficial, it also leads to higher load on the communication channel, which poses a problem, especially when considering IEEE 802.11p V2X communication. To overcome this problem, several mitigation strategies were formulated by ETSI. In the literature, several simulation studies regarding the effect on the communication can be found. Goal of this paper is to enrich the discussion with measurements from a real vehicle, showing how many objects might be available for CPM inclusion in the near to mid future.enfalseCollective Perception MessageCPMETSI ITS-G5IEEE 802.11pMitigation StrategiesV2Xconference paper
