Integrated Round Trip Path Dual Registers (RTPDR) Fault Detection

The numerous application of wireless sensor networks (WSNs) in every facet of today's world demands prompt detection and classification of faults. In this paper, an integrated round trip path dual registers (RTPDR) is presented which combines Round Trip Paths (RTP) and Dual Registers (DR) for detection and classification of node failure, node reboot and link failure diagnosis. Round trip path is adopted for nodes grouping and threshold monitoring. Detection and classification of faults are done by comparison of dual registers using each path traversed by a packet from the source node. Two different registers are kept and updated respectively depending on the path traversed by a packet to detect anomalous behaviors. The results from simulation in MATLAB demonstrates the proposed technique achieves better detection latency, false alarm rate and false positive rate when compared with existing protocols.
