Low Power Design of BAN Node for Healthcare System

摘要

In this paper, we design and implement a body area network (BAN) based on ZigBee to detect physiological parameters data. The main content can be divided into the design of end node (EN) and sink node (SN). EN collects data by physiological parameter sensor, processes the collected data and sends the data to SN. SN receives all EN’s data, and transmits data to PDA(Personal Digital Assistant) in certain format. PDA sends the received data to the internet or saves it to database. The performance is evaluated through numerical results. The results indicate that the system not only have superiority on complexity, but also have a low power consumption.
