摘要：
A wireless sensor network for wirelessly monitoring a medical subject includes a plurality of sensor nodes (22, 24, 26, 122, 124, 126). Each sensor node includes a wireless transceiver (46) for sending and receiving wireless messages, a sensor (40, 42, 130, 132, 140, 142) monitoring a characteristic of the medical subject, and a processor (50). The processor is programmed to at least perform an authentication method including: (i) acquiring sensor data via the sensor for a predetermined time (76) responsive to receiving a wireless trigger message (ii) storing an association code (60, 150, 152, 160, 162) computed from the acquired sensor data and (hi) authenticating a subsequently received wireless message containing an association code tag by comparing the association code tag with the stored association code. The processor further attaches the stored association code as the association code tag in messages sent to other sensors.
