However, these scenarios were created specifically to compare
and evaluate CARTIM’s message relaying process with
the presence of obstacles. Table V shows that scenario 2
experienced an increase of approximately 2.5% in the message
loss rate compared with scenario 1. This occurs because of
the obstacles. However, due to the specificity of vehicular
networks, the rates achieved do not compromise the functioning
of CARTIM. Moreover, as congestion increases, vehicle
density in the area also increases, which in turn decreases the
mobility of nodes in the network, thereby reducing message
losses. This statement is verified in Table V, which compares
message loss rates in scenarios 1 and 2 with scenarios 3, 4, 5.
