An Approach to Prevent Gray-hole Attacks on Mobile ad-hoc Networks

Wireless communication is used to establish connection between nodes that communicate with each other. MANET (Mobile ad hoc Network) is having Open nature that makes it vulnerable for various security threats. These vulnerabilities allow the attacker to compromise the network and degrade the performance of the network. Gray-hole attack is one of the dangerous attacks. A gray-hole attack is extremely standard and applies on network layer by targeting vulnerabilities of routing protocols. This work considers gray-hole attack as study target and derives mechanism to spot and stop MANETs from security threat. The entire works take into account Ad-hoc on Demand Routing protocol and prevention of Gray-hole attack in MANET on AODV protocol.
