Efficient symmetric cryptographic
method with Ariadne which is a
secure on demand routing protocol
No trusted environment needed
Routing protocol used here is less
efficient than the optimized version
of DSR
Dynamic learning method

with
Training data can be updated
according to the changing network
environment
Updating training set is a tedious
process.
Adaptive Probing technique with On
demand secure Byzantine routing
protocol.
Route discovery is Based on the
aggregate signature.
Does not provide effective solution
to the attacks other than the
Byzantine attacks.
Dempster – Shafer Theory
Valuable tool for the evaluation of
risk in engineering applications
when it is not possible to obtain a
precise measurement from
experiments.
It does not support the non
associative and weighted
combination of rule which is
required in most of the cases.
IV. CONCLUSION
Risk mitigating technique is one of the major issues in Mobile
Ad Hoc environment. This paper surveyed the various existing
Risk Mitigating techniques in MANET environment and
compares their various parameters. Earlier Risk Mitigating
technique does not consider the Risk because of countermeasure.
Therefore there is a need to implement a new Risk Mitigating
technique that can consider both the Risk because of attacks and
Risk because of countermeasure in MANET environment.
