Mobile Ad hoc networks are becoming popular with the advances in wireless technology. In MANET the main issue is the security management. When it comes to node level a trust scheme is needed for secure transmission of data. We have to ensure that a minimum trust is guaranteed for each node. In this paper a review is conducted on the basis of a trust model proposed for MANETs including two methods for trust evaluation, Direct Observation and Indirect Observation. Uncertain reasoning derived from artificial intelligence used to evaluate the trust values. In direct observation method a node is directly observing the other node to which it has to send the data. Then calculate the trust value using Bayesian Inference. Indirect observation deals with observing nodes indirectly from neighbor nodes. Then calculate the trust value using Dempster Shafer Theory. Bayesian Inference and DST are coming under the field of uncertain reasoning. Values obtained from these two components are combined to get more accurate trust value. Routing protocol OLSRV2 is used to evaluate the trust model. With this proposed scheme throughput and packet delivery ratio can be improved.
