Abstract—In wireless sensor network probability of fault occurrences are very high mainly for physical deployment and wireless communication policy. Faulty sensors node and transmission fault decreases the network quality. It is most important to tolerate the faults which occur in network to improve the network quality. In wireless sensor network, energy is most considerable thing because each sensor node has a constant power supply. In this paper, we propose group based fault tolerant scheme (GBFTS) for fault tolerant and energy efficient routing in wireless sensor networks. In this technique sensor nodes are organized into some levels and groups. Each node communicates to other node on the basis of level and group. The GBFTS technique recovers data transmission failure, sensor node failure and data transmission delay with the help of alternative node connection in different network levels with minimum energy loss. The simulation result shows that the GBFTS recovers maximum number of sensor node failures or transmission failures. The result shows that the GBFTS technique transmits data very fast in normal and faulty environment.
