The presence of soft faulty sensor nodes in wireless sensor networks (WSNs) creates problem for maintaining the consistent performance over the entire life span. For this, a distributed fault detection algorithm is proposed which is based on the neighboring coordination technique. The sensor node characteristics are accumulated at a particular time instant to compute the faulty status. In this approach the number of message exchange to identify the faulty sensors is less and also saves substantial amount of energy of the sensor nodes. The proposed algorithm is implemented in NS3. The simulation result shows that the detection accuracy is better compared to other detection techniques.
