A wireless sensor network is a distributed network system consisting of distributed nodes called sensors. Sensor nodes are disposed to have errors. It is thus needed to sense and locate defective sensor nodes to ensure the quality of service of sensor networks. The authors propose an asynchronous based wakeup scheduling scheme, which optimizes energy saving ratio and achieves bounded neighbor discovery latency, without requiring time synchronization. Heterogeneous duty-cycling causes transmission latencies to be time-varying. Hence, the routing problem becomes more complex when the time domain must be considered for data delivery in duty-cycled WSNs (Wireless Sensor Networks).
