However, for data collection in a wireless sensor network, since the set of communication nodes is limited and the transmission directions are toward the sink, we show that a less strict set of interference neighbors can be defined. Based on this observation, we develop an efficient distributed wake-up scheduling scheme for data collection in a sensor network that achieves both energy conservation and low reporting latency. © 2009 IEEE.Communication protocol | Power saving | Sensor network | Slot/code assignment | Wireless network[SDGs]SDG7journal article10.1109/LCOMM.2009.0907122-s2.0-70450277220https://api.elsevier.com/content/abstract/scopus_id/70450277220
