Exposure and Anticipation of Black hole attack: A Literature Review

computer science engineering

Mobile ad hoc network (MANET) is a self-configuring infrastrucless wireless network. In this all mobile nodes behaves as a router and they can select and forward the packets. There is several routing protocol in which AODV is one of the most useful protocol for delivering the packets from source to destination. But due to the dynamic nature of the networks it is more vulnerable to severe type of security threats such as black hole, wormhole, hello flood attack , Sybil attack etc. Black hole attack is one of denial of service attack which inject false route for the transmission of packets which behaves as “freshest” or shortest route. In the case of multiple malicious nodes that work together with cooperatively, the effect will be more. This type of attack is known as cooperative black hole attack. This paper presents the review of different proposed or implemented method for the removal of malicious node from the AODV protocol also comparing it with existing methods.
