CRYPTOGRAPHIC METHOD TO SECURE AD-HOC ON DEMAND DISTANCE VECTOR (AODV) ROUTING PROTOCOL FROM BLACK HOLE ATTACK

Abstract

Secure communication is more challenging task in Mobile Ad-hoc Network (MANET). Protocols are the common sets of rules and signals that are used to communicate over network. Ad-hoc On-Demand Distance Vector Routing (AODV) is an on-demand reactive routing protocol designed for operation of MANET. Black hole attack is an attack in which a malicious node drops all packets that it receives instead of normally forwarding those packets. This attack cause to degrade the performance of AODV Protocol and hence affect the performance parameters. To secure and enhance the performance of AODV protocol under Black hole attack, cryptographic method is used. So here, we study the performance parameters like Packet Delivery Ratio (PDR), Average end-to-end delay (AETED) and Throughput under AODV routing protocol.
