Black hole attack is one of the active DoS attacks possible in MANETs so
has got lots of attention by the researchers. Research focus mainly given to
securing existing routing protocols, developing new secure routing protocols,
and intrusion detection techniques. Researchers have proposed various
techniques to prevent black hole attack in mobile ad-hoc networks. Many studies
on MANET focus on the protocols used their security issues such as data
encryption, authentication, trust, and cooperation among nodes, attacks on the
protocols and proposed solutions or preventions. - See more at:
