# UAV Charging Station Placement in Opportunistic Networks
## 7 Routing Protocols
### State-Based Campus Routing (SCR) Protocol
Epidemic routing gives the best message delay and success rate readings among the SCR and the Spray and Wait routing protocols; however, it overloads network resources which results in high energy consumption rates. SCR shows almost the same message delay and success rates as Epidemic routing with the best energy consumption performance that makes it competitive

We conclude that SCR performs the best when it comes to the overall network performance as it succeeded in maintaining a good balance among all the metrics used.
