In Wireless Sensor Network every Sensor node having a tendency to shut down ,due to computation power, Hardware Fail, Software Fail, environmental Condition and energy depletion. Fault Tolerance is a major problem in a wireless sensor Network. A Fault Management is key of Network Management. Fault management Algorithms is divided into fault detection, fault diagnosis and fault recovery.The fault detection schemes classified in a two types: Centralized Approach and Distributed Approach.Fault diagnosis is the whole process of fault management. In a Fault Diagnosis cover only three question like where the fault is located,what type of fault it is like node failure,how a fault does occurs. Fault recovery is the last phase of the fault management process. The various algorithms are available for the recover the Faulty Node like FNR Algorithm. The increase the Lifetime of WSN Using Fault Node Recovery Algorithm when Sensor Node is dead. Fault Node Recovery Algorithm it depend on Generic Algorithm and Grade Diffusion Algorithm. The algorithm can result in fewer replacements of sensor nodes and more reused routing paths. This Algorithm also increases the number of active nodes, reduces the rate of data loss and reduced energy consumption.
