Both social based as well as location based routing protocols were tested and compared with CALAR in this scenario.

Even though CALAR achieves better performance as compared to other protocols, the rate of increment in performance is less as compared to results obtained in Map based mobility model scenario.

CALAR achieved nearly 35% (Figure 15) increment in delivery ratio as compared to community based routing protocols and nearly 75% increment in delivery ratio as compared to location based routing protocols (Figure 16).

The simulation results of CALAR in different DTN scenarios show its improved performance over other existing community and location based routing protocol due to its better selection of relay nodes that belong to the destination community and are moving towards destination.
