The Improved Overhearing Backup AODV Protocol in MANET
Table 5
Evaluation of the results under attack.
| Scenario | Overhead | Delay | Packet delivery ratio |
| Black hole attack scenario | Under black hole attack, the overhead was almost the same. | In this attack, delay will increase when there are more nodes. | The most packet delivery ratio belonged to M-AODV. |
| Wormhole attack scenario | Under wormhole attack, M-AODV had higher overhead. | Under wormhole attack, M-AODV delay has been improved compared to AODV. | Under wormhole attack except in the situation with 50 nodes, the most packet delivery ratio belonged to M-AODV. |
