WBAN: Wireless Body Area Network

Wireless Body Area Network (WBAN) is a network of wearable computing devices that are in contact with or close to the body. These devices are used to monitor and control various aspects of a person's health and well-being. WBANs are also known as Body Sensor Networks (BSNs) or Medical Body Sensor Networks (MBSNs).

Components of a WBAN

  • Body Sensor Units (BSUs): These are the individual sensor nodes that collect data from the human body. They can be embedded in the body, attached to the skin, or integrated into wearable devices.
  • Central Unit (CU): This is the central processing unit of the WBAN, responsible for collecting, processing, and transmitting data from the BSUs. It can be a standalone device or integrated into a smartphone or other wearable device.
  • Communication Channel: This is the wireless link between the BSUs and the CU. It can be based on various wireless technologies like Bluetooth, Zigbee, or proprietary protocols.
