Fault-diagnosis becomes an important building block to establish fidelity in MANET. Distributed system-level diagnosis is an important problem in MANET whose purpose is to have each fault-free mobile node to determine the state of all the mobile nodes in the system. The parameters such as diagnostic latency and message complexity are used for evaluating the proposed diagnosis algorithm Crash fault and value faults are challenging problem in MANET. Cluster based architecture is used for diagnosis the fault. The dynamic environments of nodes are used in mobile ad hoc network. Crash faults due to out of transmission range, battery depletion or physical damage. Value faults are due to improper communication of nodes. The faults are finding by the use of heartbeat testing mechanism.
