Wireless communication system between medical devices using cognitive technology

A wireless communication apparatus between medical devices using a cognitive technology, the apparatus comprising:

• an interference signal sensing unit configured to sense an internal interference signal that affects frequencies that are available in a predetermined area;
• a receiver configured to receive assigned frequencies from a local channel coordinator, and to receive sensing information from at least one sensor node;
• a transmitter configured to transmit the sensed internal interference signal to the local channel coordinator;
• and
• a control unit configured to determine a frequency to be reassigned to the at least one sensor node among the assigned frequencies based on the internal interference signal.

A wireless communication method between medical devices using a cognitive technology, the method comprising:

• receiving, from an external frequency coordination database server, state information of frequencies that are available in a predetermined area, and storing interference information associated with the frequencies;
• sensing an external interference signal that affects the frequencies outside the predetermined area, and an internal interference signal that affects the frequencies within the predetermined area;
• determining a priority of each of the frequencies that are available in the predetermined area based on the interference information, the external interference signal, and the internal interference signal;
• and
• assigning a frequency based on the priority.
