A Body-Coupled Communication and Radio Frequency Dual Technology Cooperation Protocol for Body-Area Networks
Body-Area Networks (BANs) are Wireless Sensor Networks (WSNs) that operate in close proximity to the human body, being used for example for distributed wireless medical body sensors. Current implementations of BANs use standardized Radio Frequency (RF) technologies like IEEE 802.15.4, and do not account the characteristics of the body channel, e.g., strong attenuation of high frequency radio waves. In order to provide high reliability as well as energy efficiency while communicating close to the human body, a new technology called Body-Coupled Communication (BCC) was developed. As it uses the human body as channel, it does not suffer from shadowing and enables efficient and reliable data communication between nodes in close contact with the human body.
