Discovery Mechanism in the 5G-VANET Milieu

The petty important performance evaluation metrics which are used to measure the performances of the service discovery mechanism in the 5G-VANET milieu are vehicle user to target delay, success rate, response time, average bandwidth consumption, delivery ratio, packet order ratio, collision ratio, and duplicate packets ratio. The performance evaluation metrics are stated in the definition:

Vehicle User-To-Target Delay: The vehicle user-to-target delay determines the delay in terms of milliseconds from sender to receiver. It includes the queuing delay, processing time, and retransmission delay.

Success Rate (SR): SR determines the failed and successful transactions. Response Time: A response time determines the average time consumption between the response and request.

Average Bandwidth Consumption: It calculates the average bandwidth consumption for a single transaction.

Delivery Ratio: Delivery ratio is calculated by packets delivered to the packet sent, in terms of numbers. It determines the number of successful delivery of packets.

Packet Order Ratio: The packet order ratio determines the received packet order.

Collision Ratio: The collision ratio is calculated by packets collided to the packets sent in numbers.

Duplicate Packets Ratio: The duplicate packets ratio is calculated by determining the duplicate packets at the destination, estimated in numbers.
