Journal On Wireless Communication Networks 2320 - 2351 3 3 18 24 Adhoc Networks, Trust, Routing Protocol ,OLSR (Optimized Link State Routing) In Adhoc networks, nodes will be trusted implicitly based on cooperation between the entities involved in routing operations. As wireless ranges of nodes are limited, the nodes cooperate with their neighbors in order to extend the entire size of the network. Trust is taken as security solution for OLSR protocol which fits particularly with characteristics of ad hoc networks. The explicit trust management allows entities to reason with about trust and to take decisions regarding other entities. In this paper, analysis of implicit trust for the OLSR protocol using trust specification language have been done and it is shown how trust based reasoning can allow each node to evaluate the behavior of the other nodes. After the detection of misbehaving nodes, the prevention and countermeasure have been proposed to resolve the inconsistency. The same analysis of implicit trust using trust specification language can be implemented in other protocols. October - December 2014 Copyright © 2014 i-manager publications.
