Channel Modeling and Characterization for VLC-Based Medical Body Sensor Networks: Trends and Challenges

Optical Wireless Communication (OWC) refers to transmission in unguided propagation media through the use of optical carriers, i.e., visible, Infrared (IR), and Ultraviolet (UV) bands. In this paper, we focus on indoor Visible Light (VLC)-based Medical Body Sensor Networks (MBSNs) which allow Emitting Diodes (LEDs) communicate between on-body sensors/subdermal implants central hubs/monitoring devices while also serving as a luminaire. Since Quality-of-Service (QoS) communication systems depends heavily realistic channel modeling characterization, paper aims at presenting an up-to-date survey works activities for MBSNs. The first part reviews existing IR-based MBSNs models based VLC are derived. second review provides details VLC-based according mobility patient’s body. We present approach called site-specific ray tracing that considers skin tissue hospital scenarios.
