Method for measuring physiological data with a body area network

A method for measuring physiological data with a body area network (BAN) architecture including a plurality of ultra-wideband (UWB) BAN node devices, a control node device, and a remote node device, the method comprising:

• mounting the plurality of ultra-wideband (UWB) BAN node devices on a human body,
• measuring, by the plurality of UWB BAN node devices, real-time physiological data of a patient, wherein the real-time physiological data include a pulse rate, a body temperature, an electrocardiogram (ECG) activity, and an electroencephalogram (EEG) activity;
• transmitting, from the plurality of UWB BAN node devices to the control node device, the physiological data using UWB signals;
• encoding, by the control node device, the UWB signals using a spectral amplitude coding-optical code division multiple access (SAC-OCDMA) encoder;
• modulating, by the control node device, the encoded UWB signals using an on-off keying (OOK) scheme;
• combining, by the control node device, the modulated UWB signals into an optical signal using an optical coupler;
• transmitting, from the control node device to the remote node device, the combined optical signal through a free space optics (FSO) link;
• decoding, by the remote node device, the combined optical signal using an SAC-OCDMA decoder;
• converting, by the remote node device, the decoded optical signal into an electrical signal;
• and
• analyzing, by the remote node device, the physiological data of the patient based on the electrical signal.
