MAODV: To Identify a Secure Route Selection in MANET under Blackhole
Sumer Singh, Chakshu Goel, Gurjeevan Sandhu · International Journal of Computer Applications · 2012
Mobile Ad-hoc Network (MANET) is an open loop infrastructure, having independent movement of each node without any decentralized control. Due to dynamic nature. MANET has a many security issues than conventional networks. In this paper AdHoc on Demand Distance Vector (AODV) is used as a routing protocol in MANET. Many types of attack are introduced in MANET such as blackhole attack, wormhole attack,routing table overflow attack, routing cache poisoning attack etc.,which occur due to the malicious node and degrade the achievement of AODV. In this paper, blackhole attack is taken into consideration which is more dangerous than other attacks. To maintain a secure route selection under blackhole attack, it is necessary to make a strong security proposal, which maintain the performance of network. This paper introduces a new security scheme which deals with MAODV (Modified AdHoc on Demand Distance Vector) which enlarges the performance of network and eliminates the risk of blackhole attack in the presence of malicious node.
