摘要： Provided is a wireless sensor network operating method considering energy efficiency. The method for operating a wireless sensor network including clusters of sensor nodes includes: selecting a cluster head based on residual energy amounts of the sensor nodes by increasing a probability that a sensor node with a greater amount of residual energy than the others is selected as a cluster head; transmitting an advertisement message from the selected cluster head to the sensor nodes to form a cluster; and transmitting sensing data acquired in each sensor node to the cluster head. Accordingly, this method can extend lifespan of sensor nodes by not transmitting/receiving data on residual energy amounts and positions between sensor nodes, and increase the entire lifespan of a wireless sensor network by reducing a probability that a sensor node having a relatively small residual energy amount is selected as a cluster head consuming much energy.
