Improving Power Efficiency in WBAN Communication Using Wake Up Methods

Power efficient communication in a Wireless Body Area Network (WBAN) is critical for successful system deployment. Stringent constraints of size and weight of sensors significantly limit available sensor power, particularly in the case of implantable sensors. This paper discusses and analyses methods that could be used to improve power efficiency of implantable WBAN systems, with focus on the Wake Up Radio (WUR), which allows power efficient listening of wireless channel. The paper presents analysis of existing hardware and design trade offs in WUR implementation.
