The dependability of Wireless Sensor Networks (WSNs) is laid low with faults which will occur attributable to varied reasons like malfunctioning hardware, software system glitches, dislocation or environmental hazards, e.g. fire or flood. A WSN that's not ready to take care of such things may suffer a discount in overall lifespan, or lead to hazardous consequences in important application contexts. In the authors' proposed paper, they will propose the fault tolerance mechanism by finding the fail over scenario and will select the backup cluster head. In case of failure of primary cluster head, back up cluster head will take place of primary cluster head automatically.
