Detection of Black Hole Attack With Improved AODV Protocol in Manet

Lalita Prajapati, Anurag Singh Tomar

Ad-hoc network is a collection of dynamic nodes it means any node can join the network and leave the network any time. Wireless communication is less secure than wired communication and that’s why it is the vulnerability of mobile ad-hoc network and any threat can easily affect the communication. Many types of attacks are developed today which badly crash the network and make the communication performance degrade. So for avoid these vulnerabilities and make network secure we propose the technique on SECURITY of mobile ad-hoc network. To provide the security of mobile ad-hoc network we generate new techniques for detection of black hole attack. Black hole attack is type of malicious node who drops the packet instead to send that packet to their destination.
