Body Area Network (BAN) or Body sensor network (BSN) are terms used to describe the application
of wearable computing devices. BSN consists of a large number of smart sensors that have limited
computing, storage, communication and energy resources. The sensors that are worn in the human body
will collect various physiological changes in order to monitor the patient's health status. The information
will then be transmitted to a system/home pc which processes the data and then transmits it to the server
at frequent intervals, where the data is stored in a uniform format in relational database irrespective of
client side systems database format.
