Health Diagnosis Using Wban Technology

Abstract

Invention of the low power consuming wireless sensors are raising the emergence for the usage of wireless body area networks (WBAN).WBAN is widely used in many applications such as entertainment, gaming, army etc this is widely used for active applications as it provides instant monitoring .So, this is very useful for healthcare sensing which provides effective monitoring with the help of tiny sensors. In, this paper we discuss about the architecture of health monitoring system using WBAN, how to overcome the path attenuation, devices used in this WBAN, body sensor network and security. Keywords: WBAN, Health monitoring system (HMS) , Path Attenuation , Body sensor network, security. I. Introduction Now a days health is the at most concern for the people in our country due to the increasing population the health problems are also getting worse due to their change of lifestyle and they are not even having time to visit a doctor and sometimes during the times of emergency the doctors may not be available so keeping this in mind our technology has new advancements in the field of health so as to save people from problematic situation. This technology is helping the old who are weak from going to the clinics regularly they can happily verify their health condition by sitting in their home. This WBAN uses tiny sensors for determining the health condition which are placed on or around the body. The sensors are placed on the body or around it and these sensors collect the data regarding the health and then after this the WBAN uses data transfer mechanisms like bluetooth, wi-fi, zigbee for giving the data to the doctor. this also uses several devices such as sensor shirt, watch sensor, abdominal belt etc to collect the important data from the patients body and transfer it to the medical practitioner. The path loss depends on the distance of the transmitter and receiver. The different types of sensors used for different body parts and based on body communication we use different antennas. The sensors whish are placed on the body collect the data about our body now to transfer the data to the physician first it should send the data to the remote server using a base station transceiver(BST) this is then connected to the sever pc. The health monitoring system is component based so it consists of bluetooth and smart phone for maintaining patients health condition and his location with help of a accelerometer which acts as intelligent control node(ICN).As we have different types of architectures for WBAN such as sensor shirt, watch sensor, abdominal belt etc we gather data from sensors and using zigbee which is more power efficient than bluetooth that data will be transferred to doctor using a BST which is connected to the server pc. The sensor shirt is a multi-hop sensor network.
