Accurately positioning nodes in wireless sensor networks is very important because the location of those devices and sensors is a critical input to many higher-level applications used for sensing. Faults occurring in the sensor nodes are commonly due to the sensor device and the environment which is harsh where the sensor nodes were deployed and used for data communication. To ensure the networks quality of service it is necessary for a WSN to be able to detect the faults and actions to be taken to avoid further degradation of the sensing service. The Extreme goal of this paper is to locate the faulty sensor nodes in the wireless sensor networks as well as to find trust for other nodes. We have propose an algorithm to deduct node fault using localized node fault detection and introducing Trust dependability to the non-faulty nodes for energy efficient data communication. The implementation complexity of this LF algorithm is less and the probability of correct diagnosis is high even in the presence of large fault sets.
