Title:Performance Analysis Of Implicit Trust Based Security In AODV Routing Protocol
Author Name:H. Muthukrishnan and K. Akila
Synopsis:
In Ad hoc networks, nodes are trusted implicitly based on cooperation between the entities involved in routing operations. As wireless range of nodes are limited, the nodes cooperate with their neighbors in order to extend the entire size of the network. The explicit trust management allows entities to reason with and about trust and to take decisions regarding other entities. In the proposed work, trust is taken as a security solution for AODV protocol, which fits particularly with characteristics of ad hoc networks. Here implicit trust for the AODV protocol has been analyzed using trust specification language and how a trust based reasoning can allow each node to evaluate the behavior of the other nodes, is shown. During route discovery, a node with more trust is selected, based on a router based parameter called 'Trust value'. Route request from the source is accepted by a node only if its trust value is high. Otherwise, the route request is discarded. This approach forms a reliable route from source to destination. The prevention and counter measures have been proposed to resolve the inconsistency for the misbehaving nodes.
