Abstract: A moving apparatus for cleaning is provided. The moving apparatus includes a cleaner for cleaning, a traveler for moving the moving apparatus, an image sensor for capturing an image of surroundings of the moving apparatus, and at least one processor configured to control the image sensor to detect at least one mark among a plurality of marks, respectively corresponding to different distances of the moving apparatus in relation to a station apparatus, from the image captured by the image sensor, and control the traveler to move the moving apparatus to a location of the station apparatus, which is determined based on the image where the mark is detected.

Abstract: A method for controlling a multi-sink/multi-path routing sensor network and a sensor network system using the same are provided. The method for controlling the sensor network includes generating, at a sensor node, sensing data; transmitting, at the sensor node, the sensing data to a plurality of sink nodes; and forwarding, at the sink nodes receiving the sensing data from the sensor node, the sensing data to a gateway. Hence, it is possible to satisfy the reliability required in the safety-critical system with the minimum traffic. Both of the two conflicting requirements which are the reliability enhancement of the sensor network and the minimization of the network traffic in the repeated data transmission, can be satisfied adequately.
