Faulty Sensor Detection for Wireless Sensor Networks

Due to the increasing growth in wireless networks in different areas, reinforcing and developing faults management in wireless sensor networks will have an important role in effective use of them, so we must identify and put aside faulty sensors so that they won’t affect the entire network performance. these faults may be transient, permanent or intermittent .The proposed method covers any defects in the sensor nodes and each sensor in a self-constructive, distributed and local manner in such a fashion that the value received from the environment periodically sends data to all its neighbors, and all sensors make decisions about this point as if the sensor is faulty based on information received from the neighbors or not. This algorithm optimizes sensor energy sources, enhances detection accuracy and reduces the error percentage in detecting faulty wireless sensor networks.
