The fall detection sensor and the other vital sign sensors
are attached on the patient or the resident. Meanwhile, the
RFID reader has been embedded on the node and used for
personal identification. The data from the RFID reader can be sent wirelessly to the base station. This can reduce the cost of
wiring in the original RFID system and also increase the
flexibility of the installation. Both wireless sensors and RFID
are connected to the wireless router (base station). The
administrator or caregiver can access directly to fall detection
or RFID devices on wireless sensor networks via Internet or
GSM
