CRYPTOGRAPHIC APPROACH TO ELIMINATE BLACK HOLE ATTACK IN MANET

In Manets, nodes usually cooperate and forward each other packets. But in hostile environment some nodes may intentionally misbehave or would not forward disrupting from communication. One of the attacks is black hole attack. The black hole attack intentionally drops the packet or jeopardize. Black hole node claims to have shortest path and participate in communication. The proposed system uses AODV encryption and decryption to prevent black hole attack .it is simulated using NS 2.34.
