ABSTRACT
Providing
security in Mobile Ad Hoc Network is crucial problem due to its open shared
wireless medium,multi-hop
and dynamic nature, constrained resources, lack of administration and
cooperation. Traditionally routing protocols are designed to cope with routing
operation but in practice they may be affected by misbehaving nodes so that
they try to disturb the normal routing operations by launching different
attacks with the intention to minimize or collapse the overall network
performance. Therefore detecting a trusted node means ensuring authentication
and securing routing can be expected. In this article we have proposed a Trust
and Q-learning based Security (TQS) model to detect the misbehaving nodes over
Ad Hoc On Demand Distance-Vector (AODV) routing protocol. Here we avoid the
misbehaving nodes by calculating an aggregated reward, based on the Q-learning
mechanism by using their historical forwarding and responding behaviour by the
way misbehaving nodes can be isolated.
