QoS metrics	Spray-and-Wait protocol	FRESH protocol
Message delivered	Best	May be improved
Message dropped	May be improved	Best
Delivery probability	Best	May be improved
Overhead ratio	Best	May be improved
Average latency	May be improved	Best
Average hop count	Best	May be improved
Average buffer time	May be improved	Best
