Abstract: A firmware updating method for the new node includes (a) a new node searching for neighbor nodes located within a predetermined distance, (b) the new node designating a parent node among the searched neighbor nodes, (c) in the case where the plurality of nodes include a join receiving state for joining the new node to the wireless sensor network, the designated parent node and the new node establishing a communication link by using the join receiving state, (d) the parent node transmitting firmware to the new node through the established communication link and (e) the new node receiving the firmware from the parent node, updating existing firmware with the received firmware, and driving the updated firmware to be jointed to the wireless network.

Abstract: A method for updating firmware of a plurality of nodes constituting a wireless sensor network is disclosed. The wireless sensor network includes a server, a gateway and the plurality of nodes. The firmware to be updated is transmitted from the server through the gateway to an uppermost node. The firmware is sequentially transmitted to the plurality of nodes from the uppermost node to a lowermost node using wireless communication, and the respective nodes, which have received the firmware, record the firmware in their own memory. When the recording of the firmware is completed in all the nodes, boot programs of the respective nodes are run and the firmware, stored in the memory, is recorded in program memory, the firmware recorded in the nodes are executed, and the nodes constitute a new network while communicating with the peripheral nodes thereof.

Abstract: A vehicle theft prevention service method and system is capable of estimating theft of a vehicle even in the case where such a two-wheeled vehicle can be moved without start-up to be stolen and a vehicle theft prevention service method and system where a user is informed of location of a vehicle at the time of estimating theft of the vehicle, so that it is possible to accurately determine the theft based on the location of the vehicle at the time of estimating the theft of the vehicle. The vehicle theft prevention service system includes an electronic key and a theft monitoring device. The theft monitoring device is installed in a vehicle and determines that the vehicle is in a theft-estimated state and transmits an alarm message if a sensed acceleration value obtained by sensing a movement of the vehicle is a predetermined value or more. The electronic key outputs an alarm if the alarm message is received. Herein, the external apparatus may be a user terminal or a server.
