摘要：A mobile ad hoc network (MANET) is formed with wireless mobile devices without the need forexisting network infrastructure. Security design in MANET is complicated because of its features including lack ofinfrastructure, mobility of nodes; dynamic topology and open wireless medium. Due to this MANET suffer from manysecurity vulnerabilities. To enhance the security, it is very important to rate the other node which is trustworthy. Hencea unified trust management security scheme is used. Sometimes the knowledge in rules is not certain. Rules then maybe enhanced by adding information about how certain the conclusions drawn from the rules. In trust managementsecurity scheme, the trust model has two components: direct observation and indirect observation. In direct observation,trust value is calculated from an observer node to observed node. On the other hand, indirect observation is alsoreferred as secondhand information which is obtained from neighbor nodes of the observer node; the trust value iscalculated between them. By combining these two components in the trust model using uncertain reasoning a moreaccurate trust value is obtained. This will help to improve throughput and packet delivery ratio in the network.
