SENSOR NETWORK BASED ON LOCATION ESTIMATION AND METHOD FOR RECOGNIZING DOORWAY OF ROBOT IN SAME SENSOR NETWORK

摘要

A position estimating based sensor network and a method for detecting a gateway of a robot in the sensor network are provided to move to a target position quickly by detecting the gateway through the communication with an RF sensor node installed around the corresponding gateway. A position estimating based sensor network includes a plurality of RF sensor nodes(100) and a movable robot(200). A plurality of RF sensor nodes are installed indoors and at least one node is installed in the gateway indoors. The movable robot receives the RF signals transmitted from the RF sensor nodes and estimates the current position and moves using the received RF signals. The movable robot includes a communication unit, an RSSI measuring unit, a storage unit and a robot driving unit. The RSSI measuring unit measures the voltage intensity of the RF signal. The robot driving unit moves the robot by driving the moving unit mounted on the robot.
