Effect of opportunistic forwarding on the VANET performance. In terms of CAM PSR, best results are achieved for a Tmax value of 200 ms and a value of 1. However, this results in a relatively large DENM delay. This configuration is called the aggressive approach. When configuring a Tmax value of 75 ms and an a value of 2, CAM PSR profit is still significant, and the DENM delay is clearly lower. This is called the balanced approach.
