Provided are a route guidance system and method for emergency vehicle using telematics. The route guidance system includes an instruction station, a vehicle telematics and a traffic signal controller. The instruction station sends destination information to an emergency vehicle for dispatch due to an occurrence of an emergency circumstance. The vehicle telematics is attached to the emergency vehicle, and searches a plurality of travel routes on the basis of the destination information to provide the shortest travel route. The traffic signal controller controls a corresponding traffic signal on the travel route before the emergency vehicle approaches on the basis of travel information sent from the vehicle telematics.

The present invention relates to a system and method of transmitting an emergency condition using a wireless sensor network that transmits a user's emergency condition using a wireless sensor network. A wireless sensor network communication device integrated with a biological sensor is attached to a user's body in order to gather user's biological information, and transmits the user's biological information through the wireless sensor network. A repeater receives the biological information from the communication device, and sends the received biological information by using a routing protocol of the wireless sensor network. A management server receives the biological information through the repeater, analyzes the biological information, and transmits a warning signal to a user or takes emergency measures. Therefore, it is possible to detect and cope with sudden physical problems, which are generated during user's exercises and outdoor activities, at an early stage. As a result, it is possible to significantly contribute to the prevention and reduction of danger for the weak and the elderly, and a user who is to be taken care of.

Provided are a node update system using virtual partition technique and a control method thereof. A storage region of a sensor node is divided into a non-updatable invariable region and an updatable variable region to be virtually generated according to an execution operation of the sensor node. The states of the sensor nodes are monitored, and an update request signal is transmitted to a corresponding sensor node when update is necessary. Execution image information is received, and the execution image information is stored in the variable region to update an execution image, according to a response signal to the update request signal.
