During the recent decade, wireless body area network (WBAN) was developed and prioritized. This gives reliability, energy efficiency, and guaranteed results. Moreover, internet of medical things (IoMT) also enhances the significance of WBAN networks. To achieve high throughput, performance, and efficiency, WBAN deserves a new protocol definition as compared to general wireless sensor network along with a more enhanced framework. The standard 802.15.6 with PHY and MAC layers follow the standardization of WBAN. The wireless nature of the network and various varieties of sensors in the presence of IoMT made it possible to develop new, effective, innovative, and demand-driven solutions for health improvement and quality of service. In the recent literature, the researchers have proposed an IoMT-based secure framework for WBAN. In this chapter, an in-depth and comprehensive depiction of the security issues of IoMT-based framework of the wireless network is highlighted that incorporates security measures in different levels of the WBAN network. © 2020, IGI Global.
