A Policy enforcing mechanism in MANET is performed to provide the secure communication. If two nodes enforce the same set of policies for two instance of application and also if the underlying protocol used by the application are the same then these two instances running on different nodes can engage in communication. Nodes can be a member of multi-tier network at the same time. A policy enforcing in MANETs challenging because lack of they infrastructure so introduce a Satem. Satem verifies the trustworthiness of the new node when it joins the tier. Policy enforcing mechanism based on Satem, a kernel-level trusted execution monitor. The security provided by the mechanism is validated by performing the security analysis. Performance of the network is evaluated using network simulator.
