Method for estimating position of multiple sensors using mobile anchor node and apparatus thereof

摘要

According to an embodiment of the present invention, a beacon signal receiving step of receiving a beacon signal from a mobile anchor node capable of grasping its own location information at a current point of time by a first sensor based on GPS, and the first sensor Location information extraction step of extracting location information of the mobile anchor node from a beacon signal, sensor location information estimation in which the first sensor estimates location information of the first sensor based on the extracted location information of the mobile anchor node A second sensor determining step of determining, by the first sensor, a second sensor from among at least one or more sensors based on the intensity of the received notification signal; And identification in which the first sensor transmits the identification information of the second sensor to the mobile anchor node, so that the mobile anchor node estimates the location information of the second sensor through repeated communication with the second sensor. Disclosed is a method of estimating a plurality of sensor positions based on a mobile anchor node including an information transmission step.
