Survey of challenges in hybrid optical wireless broadband network (HOW-B) for e-health systems

The hybrid optical-wireless broadband network (HOW-B) is shows potential future for healthcare communication systems and networks. The marvel innovations in free space optics (FSO) based wireless communication, medical sensors and mobile network technologies have associated with emerging biological fields of telemedicine and bioinformatics. On the other hand, the progressive developments in optical based wireless technology have opened up a window for life-saving network services. The wireless network along with advance modeling technique of patient-care facilitates in monitoring of the physiological data, the treatment optimization, and continuous patient-care. This provides an improvement of care and quality of patient's life without interrupt circulation in everyday life activity. In this paper, the FSO and RF networks viable connectivity and low-cost optical wireless tele-monitoring network system has been introduced. In addition, it provides review of the interoperability and QoS assurance issue, also compare various feature of optical wireless with (RF) wireless network.
