Maximum lifetime scheduling for target coverage in wireless sensor networks
Hoon Kim, Youn‐Hee Han, Sung-Gi Min · 2010
The best way to conserve energy in wireless sensor networks is to change the radio interface state to sleep mode. The sensors in sleep mode conserve energy, whereas the sensors in active mode use their energy to continue to monitor the target. How sensors are scheduled between active and sleep modes affects the lifetime of the sensor network.
