NS2 Black Hole Attack

What is Black Hole Attack?How Black Hole attack is implemented using NS2?

In Routing Protocol,a malicious node advertise itself as a shortest path routing protocol. NS2 is best suited for implementing black hole attack.

Types of black hole attack:

• Collaborative black hole mechanism.
• Single black hole.
• External black hole attack.
• Internal black hole attack.

Detection mechanisms for Implementing NS2 Black Hole Attack :

Time based threshold detection method.

DPRAODV.

BDSR.

Neighborhood based and routing discovery.

Random two-hop ACK and Bayesians detection scheme.

Redundant route and unique sequence number scheme.

REAct.

IDS based on ADM.

Hash based hashed base.
