Metric
Description
End-to-end delay
The safety message dissemination single-hop delay
Packet reception ratio (PRR)
The percentage of nodes that successfully receive a packet from a tagged node given that all the receivers are within the transmission range of the sender at the moment that the packet is sent out [18]
Packet transmission ratio (PTR)
The percentage of nodes that successfully transmit a packet given the prevailing contention for channel access
