Safety of human in body area network: A review

Abstract

Body area network is most important topic of research now a days and it is under developing technology in the field human health care. BAN plays an important role to improve human health. BAN contains small electric devices such as sensors and actuators to make a complete network. These sensors are attached with the patient body or implant under the skin of patient. Body area network (BAN) is not only used in health care bus also used in non medical applications such as military and entertainment. BAN plays an important role in the field of health care for patient monitoring to avoid the restriction in patient's daily life. BAN is simplest and fastest way to monitor patient health regularly. The potency of BAN is depended in the safety of human from its radiations and other effects. This paper describes the main feature and key components of BAN, basic structure of BAN, importance of BAN and challenges face during implanting, architecture of sensor node is described, IEEE standard that is used in BAN, different applications, physiological signal and their frequencies; data rate and latency of BAN, and describe the safety of human in BAN in details. Finally, the open research issues and challenges are also pointed out.
