PURPOSE: A method for tracing a moving target in a sensor network is provided to anticipate a next location of the target based on speed and a yaw angle of a detected target. CONSTITUTION: A moving target is detected(S520). A location of the detected target is calculated(S525). Speed of the detected target and the yaw angle of the detected target are calculated. A next location of the target is anticipated based on the location, the speed, and the yaw angle of the calculated target(S545). A sensor node which is closest to the anticipated next location and at least 2 sensor nodes selected based on the calculated yaw angle are activated(S555).
