Recent technical advancements in low-power integrated circuits, ultra low-power RF (Radio Frequency) technology, wireless communications and micro sensors allowed the realization of a futuristic health care system called Wireless Body Area Networks (WBANs). This new type of technology hold much promise for future patient health monitoring. A body area network wirelessly connects independent nodes (e.g. medical devices, earphones, sensors and actuators) attached to the body surface, implanted into tissues/body, or dispersed in the clothing for applications in home/health care, sports, entertainment, defense, ambient intelligence, pervasive computing and many other areas.
