Vanet Routing Compare Example

[jasmi]

Hello,

I am triying to understand  src/wave/examples/vanet-routing-compare.cc File .

I read all the explanations in the code file but there are some points that aren't clear in my mind. When I run it, I get the result as shown in the enclosed. 

1. What is the meaning of 3th value (I show it as bold in the next sentence) in the AODV outputs ? For example; "AODV 2.18255  6  received one packet from 10.1.0.17" . If it is one of the nodes i.d., why is it just 3, 6, 8 and 9 during all AODV outputs. It says in the code file that there are 40 nodes for scenario-1. Why is it not i.e 25 or 36 or 21 etc. ?

2. For t=2s there is 5 AODV output but there is 10 BSM_PDR value. How is it can be? I think I didn't understand also how to find BSM_PDR value for this example. I thought that if there is 5 AODV output, it can be 5 BSM_PDR value for the t=2s.

3.  There is 5 AODV output for the t=2s, 4 AODV output for t=3s, 4 AODV output for t=4s,..., 9 AODV output for t=6s etc.  Why aren't the number of the AODV outputs equal to each other in every t moment.
