A Survey Paper on Body Area Network in Healthcare System

Body Area Network (BAN) is widely used in medical healthcare systems. Under WSN (Wireless Sensor Network) technology many applications are developed in Body Area Network (BAN). In medical applications the sensor network is widely used now days. Applications like Healthcare Monitoring System, Smart Hospitality, and Continuous patient monitoring system are under Body Area Network (BAN) technology. Sensors are attached on the body of patient by which values are to be taken, analyzed for healthcare system. WBAN offers wide variety for evaluation of healthcare in medical systems. Various sensors can be connected to the on clothing or on-body and also implanted under skin. There sensors are used to calculate the parameters from the body of patient. And the values are taken from sensors is given to the analyzing device or hardware by the wired or wireless devices such as Bluetooth, Zigbee etc. BAN gives wide availability of healthcare devices all the time. Projects are done in Body Area Network (BAN) from 1976. A wearable computer, sensor network based medical monitoring system, Europian Mobihealth etc. are some of the examples of project in WBAN. Wireless Body area network is now often used in Mobile Health Application and it is emerging technology which gives facilities for human health applications.
