In wireless body area networks various sensors are attached on clothing or on the body or even implanted under the skin. The wireless nature of the network and the wide variety of sensors offer numerous new, practical and innovative applications to improve health care and the Quality of Life. Using a WBAN, the patient experiences a greater physical mobility and is no longer compelled to stay in the hospital. In this paper, we present an overview of wireless body area network and we also provide the differences between Wireless Body Area Network and Wireless Sensor Network (WSN) that is inadequate to apply in WBAN. We also present an idea to improve healthcare systems in India with the help of telecommunication and information technology by using wearable and implantable body sensor nodes which does not affect the mobility of the patients. We discuss how the wireless body area networks are used for healthcare monitoring by using multiple sensor nodes. In this paper we present various innovations and discuss promising new trends of wireless body area networks for ubiquitous health monitoring applications.
