A survey on security issues and wearable sensors in wireless body area network for healthcare system

Several works have been done in recently geared towards improving and maintaining the aging world population from chronic diseases due to our numerous activities. Researchers actively working in various fields (medical, academic, military, and industry). This survey report focuses on developing and implementing wireless body area network technology (WBAN) in healthcare systems. Body area network (BAN) technology establishes a system which monitors patient health status using tiny wireless sensors devices placed in or around the human body that aids medical professionals, and the patients with easy and convenience of operation and mobility. However, this technology faces peculiar challenges in designing and implementing, such as security vital for any system, privacy concern for everybody because it holds our data and must maintain high secrecy, power failure, sensor validation versus system compatibility, data consistency, cost and many others. Moreover, the survey suggests ways to improve and maintain the dependability of WBAN.
