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.
