A schematic review on body area networks for E-health systems

The speedy elevation in the field of Wireless Communication and Semi-Conductor technologies have led to the expansion of Sensor networks aiding a wide range of applications in field of the Wireless Sensor Networks. IEEE 802.15 WPAN Task Group 6 (TG6) has developed Communication Standards optimized for the low power Body Area Networks. The recent trends in the Wearable devices have made the World smaller and healthier by integrating portable and low power computing devices. Thus, making it feasible to track and reach the Health and Fitness goals by monitoring Physical activity, Exercise, Sleep, Heart Rate, Blood Pressure etc. In order to achieve real time Fitness monitoring, multiple Sensor nodes are either placed externally or implanted inside body. These nodes yields the Bio-information of the patient supporting Quality of Service (QoS) for extremely low power application. The obtained information from the sensor nodes is passed on to the E-Cloud by means of E-Health platform. Various E-platforms have been launched encouraging the integration of new and existing networks to maximizes the scope of WBAN. This paper evaluates and reviews the latest low power Wireless systems and the future scope of Tele-Monitoring and Mobile Health (mHealth). It highlights the evolution of Body Area Network with Wireless Technologies and existing Standards addressing health priorities.
