Wireless Body Sensor Networks

Definition

Wireless body sensor networks (WBSNs) are a collection of interconnected sensors worn on or implanted in the body that monitor physiological parameters and transmit the data wirelessly. These networks facilitate real-time health monitoring, allowing for continuous data collection and transmission to healthcare providers or personal devices. WBSNs enhance the ability to track health metrics, enabling early diagnosis and management of medical conditions.
