Radio Frequency Propagation Characterization, Statistical Channel Modeling, Interference analysis and Mitigation in Body Area Networks

Description

A body area network (BAN) is a wireless network consisting of small, low power, wearable, implantable or ingestible devices. Integrated with various biomedical sensors or actuators, these devices basically provide data communication paths between the human body and the external world. As such, they are regarded as the fundamental components in IoT-Health. Knowledge of the radio frequency propagation on the surface, or inside the human body is the first step in understanding the communication channel among wearables or medical implants. However, physical experiment is extremely difficult, if not impossible, for scenarios involving the human body. Using a 3D computational human body model, an immersive visualization platform has been developed at the Applied and Computational Mathematics Division of ITL to study the wireless channels between wearables, implants and ingestible devices. Using this platform, the objective of this project is to conduct an in-depth study of the communication channels in body area networks for various physiological monitoring applications.
