Generally, fault detection approaches pursue high detection accuracy, but neglect energy consumption due to the high volume of messages exchanged. Therefore, in this work we propose a reactive distributed scheme for detecting faulty nodes. The scheme is able to detect transient and permanent faulty nodes accurately by exchanging fewer messages. In existing fault detection schemes, nodes exchange too...
Currently available fault detection approaches generally pursue high fault detection performance but neglect energy consumption due to high volume of messages exchanged during fault detection process. Therefore, in this work we propose a reactive distributed scheme for detecting faulty nodes. The scheme is able to detect transient and permanent faulty nodes accurately with very less false alarm rate...
In wireless sensor networks (WSNs), sensor nodes are deployed densely in large numbers to increase the quality of services (QoS). However, QoS is significantly affected by faults in such networks. The probability of faults in WSNs increases with increase of sensor nodes. In order to provide better QoS, it is essential that faulty nodes should be diagnosed and handled timely without affecting the underlying...
Since sensor nodes in wireless sensor networks (WSNs) are deployed randomly in hostile and ill-disposed environments, failures occur more frequently and unexpectedly as compared to other traditional networks. These frequent faults and failures in the network are major attributes towards poor quality of services (QoS). Therefore, for providing better QoS, such failures should be identified and recovered...
