Wireless Sensor Networks (WSN) can be used to monitor the people environment, objects in that environment and interactions of objects with each other. Use of WSN for emergency applications includes fire detection system in forest, soil motion detection, monitoring historical and public places, volcano monitoring etc. In WSN errors or faults tends to occur frequently due to node mobility or energy shortage (battery limitation). Faults cannot be tolerated in WSN for emergency applications, hence fault tolerance is an important issue in network design and thus networks have to be tolerant of error and fault.
