Method, system and device for scheduling sensor nodes in wireless sensor network

The embodiment of the invention discloses a method, a system and a device for scheduling sensor nodes in a wireless sensor network. The method comprises the following steps: acquiring a network connection relationship and a target coverage relationship of each sensor node; acquiring an output result by a column generating method according to the network connection relationship, the target coveragerelationship and a coverage requirement, wherein the output result comprises the number of time slices required by different working modes; acquiring a schedule table according to the output result;and broadcasting the schedule table in the wireless sensor network to schedule each sensor node. The method, the system and the device implement the scheduling of the sensor nodes in the wireless sensor network by the column-based generating method, and reduce power consumption required by the wireless sensor network to monitor target nodes.
