# On the Potential of Enhancing Delay-Tolerant Routing Protocols via Age of Information
## 4 Protocol Evaluation
### Larger-Scale Simulations  
In this subsection, we present the results obtained from more extensive simulations, in which the behavior of the six versions studied in the work is examined by changing parameters, such as the number of DTN nodes, the number of time slots, as well as the value of the Bound for the AoI (for the three versions of the modified protocol). The results are shown below in Tables 8-13: \begin{table}
