Devices in energy-limited wireless sensor networks remain in a low-communication 'sleep' mode until an alarm event is detected. It has been proposed to use 'censoring sensors' to reduce the probability that a sensor must transmit in this mode, thereby minimizing energy consumption when alarm events are not occurring, and lengthening sensor lifetime. Further, since devices in multi-hop networks are not usually in single-hop range of a fusion center, hierarchical distributed detection can lead todoi:10.1109/ssp.2003.1289329 fatcat:bouaj3utuza2pepzgxs6syz5ue
