Description

MANET is a collection of mobile nodes communicating in a multi hop manner without any fixed infrastructure such as access points. MANET is not immune to attack making it easy for the attackers to easily access this kind of network. In this project we analyze the behavior and impact of Jellyfish attack over TCP-based MANETs. The compromised/malicious node alters the packet, drop the packet or delay the forwarding behavior in transmission process. MANET is a collection of mobile nodes communicating in a multi hop manner without any fixed infrastructure such as access points. MANET is not immune to attack making it easy for the attackers to easily access this kind of network. In this project we analyze the behavior and impact of Jellyfish attack over TCP-based MANETs. Jelly fish attacks are targeted against closed loop flows. TCP has well known vulnerabilities to delay, drop and disorder the packets. To combat the attack and optimize the network and provides defense to Mobile Ad Hoc Networks against this technique we enhanced the strong novel mechanism. Jelly fish attacks are targeted against closed loop flows. TCP has well known vulnerabilities to delay, drop and disorder the packets. We proposed a RSA algorithm to detect and remove a Jellyfish node.
