摘要： A power-saving method of wireless communication device, which operates a sleep mode for minimizing power consumption except for an active mode for communication, initializes a sleep probability upon the device being turned on, operates the active mode for communication with starting an active mode timer, transits to the sleep mode when there is no packet to transmit or receive before the active mode timer expires; and determines an exit from the sleep mode on the basis of the sleep probability.

摘要： A power saving method of the present invention is provide for a wireless sensor network including a plurality of sensor nodes each transiting between a power saving mode and a transmit/receive mode, determines whether or not there is no transmit or receive data, enters the power saving mode if there is no transmit or receive data, and controls power consumption on the basis of signal-to-noise ratios in the power saving mode. In the power saving method of the present invention, it is possible to minimize the power consumption regardless of nodes density and without an adverse effect on the connectivity of the network, since the sojourn times of the sleep and idle states are determined adaptive to the interference level from neighboring nodes.
