Risk Mitigation of Black Hole Attack for Aodv Routing Protocol
Varsha Patidar · IOSR Journal of Computer Engineering · 2012
Due to the flexibility and independence of network infrastructure, MANET is a hot research topic among researchers.MANET is dynamic infrastructure less in nature and lack of centralized monitoring points and such network are highly vulnerable to attacks.The performance and reliability is break by attack on Ad hoc routing protocols.Nodes can leave and join the network at any time.AODV is an on demand routing protocol for MANET.In AODV protocol, security is compromised by "Black Hole "attack.A black attack is a severe attack that can easily employ against routing in MANET.In black hole attack, a malicious node that falsely replies for an rout request without having an active route to specified destination and drops all the receiving packets.In this paper we will focus on various techniques on how black hole attack can be detect and mitigate in AODV routing protocol and will also compare the existing solution to black hole attack on AODV protocol and their drawback.
