MANET Attack Prevention - All across the world, majority of humans rely upon wireless ADHOC network. So, it turns into the maximum priority to lessen the vulnerability of wireless network. Wireless networks are exposed to many distinct varieties of attacks out of which wormhole attack is most dangerous. Unlike many different attacks on ad hoc routing, wormhole attack could be very effective and cannot be avoided with cryptographic approach due to the fact intruders do now no longer modify the packet data, it replays the packets. An intentionally positioned wormhole can cause a significant breakdown in communication. An analysis was performed in this study that removed wormhole attacks from MANET using changes to the AODV routing protocol. We have used Smart Packet Detection and Prevention Technique (SPDPT) to remove Wormhole. We have examined simulation parameters such as packet delivery ratio, end-to-end delay, energy consumption, and throughput.
