State Of The Art : Security In Wireless Body Area Networks

--Advances in wireless communication technologies and sensors have scepter development of Wireless Body Area Network (WBAN). The wireless nature of network and sort of sensors provide various new, sensible and innovative applications to enhance health observance and alternative health care applications system. Within the past few years, several researches targeted on building system design of health observance to enhance the technical demand specifically designed for WBAN. However, as a part of communication medium, WBAN faces with varied security problems like loss of information, authentication and access control. Less research were found in providing robust security system in WBAN. Throughout this study, we tend to believe that WBAN will offer varied applications together with medical and non medical. During this paper, we tend to gift an summary of body area network and their connected problems stress in security downside. We tend to conjointly offer the variations between Wireless Body Area Network and Wireless Sensor Network (WSN) that is inadequate to use in WBAN though some challenges visaged by WBAN area unit in many ways just like WSN. Finally, we tend to highlight security challenges that also have to be compelled to be addressed to create WBAN actually present for a wide range of applications.
