Wireless Body Area Networks and Its Emerging Technologies in Real Time Applications

With the rapid improvement of wireless communication and semiconductor technologies, the body area sensor network (BASN) is fast developing. The BASN which is also referred to as the WBAN (Wireless Body Area Network), is widely used in medical applications and comprises of Body Sensors attached to human body. These body sensors will help to monitor the interior functions of the body. The data generated by the sensors is transmitted via the internet and collected in external servers which are then used for analysis. The sensors being flexible and compact consume less power and provide a perfect environment for wireless sensing research. The main area of application of the WBAN is the medical field although it can also be extended to other areas like gaming, entertainment, road safety etc. These sensors will help to increase sensitivity and specificity. These days body sensors are emerging as wearable computers such as Computer clothing, Google glass, Smart watches etc which paves the way for using it in many more real time applications. In this paper we have discussed in detail about the architecture, application areas, and characteristics of the WBAN and how they are attached with the human body. WBAN is a sure platform that will dominate all the future wireless application
