Wireless Body Area Network (WBAN)

A Wireless Body Area Network (WBAN) is an advanced wireless communication system made up of small, intelligent sensor nodes positioned on, inside, or near the human body. These sensors constantly track physiological measurements such as heart rate, body temperature, blood pressure, glucose level, and oxygen saturation, then send the gathered information wirelessly to a central coordinator device. The coordinator then transmits the data to medical servers for additional analysis and diagnosis. In modern healthcare, WBAN has a major impact by supporting real-time patient monitoring, lowering hospital visits, and improving healthcare service quality. Beyond healthcare, WBAN is used in areas such as sports, military, and entertainment. This paper offers an overview of WBAN, covering its architecture, applications, benefits, challenges, and future direction.
