An Efficient Security Enhancement of AODV Protocol

AODV routing protocol is widely used in mobile ad hoc networks, but it does not have any security mechanism, so it is very vulnerable to security attacks. This paper analyses the common threats of AODV and then a security improvement is carried out. By setting up blackholes and rushing attack models, the performance of improved protocol is simulated using QualNet simulation tools. The results show that our security enhanced solution can not only protect against those attacks but also maintain the efficiency of AODV.
