چکیده (انگلیسی):

MANET networks are defined as the wireless self configuring networks that are capable of operating
without the support of any fixed infrastructure and a central coordinator which makes the routing a
complicated task. For detecting misbehaving and selfish nodes between the intermediate nodes it is essential
to evaluate the Intermediate Trust Value (ITV) for each node in the network, so that malicious node is
isolated. A threshold value is maintained and if the ITV of a node falls below the threshold value, then it is
considered as a misbehaving node and are avoided for data communication in a MANET network.
Simulation results are evaluated under blackhole attack which also proves that the proposed Authenticated
Trust based AODV protocol (AT-AODV) eliminates blackhole attacks and performs well in malicious
nodes isolation which increases the packet delivery ratio.
