Abstract

This paper addresses the energy efficiency of impulse radio(IR-UWB) based wireless body area networks (WBAN). An energy efficiency optimization model is proposed for the IR-UWB WBAN which is based on a generic wake-up radio(WUR) based medium access control (GWR-MAC) protocol. GWR-MAC takes advantage of the WUR to decrease the network energy consumption especially in applications with rare events. Energy efficiency gains are enabled by using a dual-radio approach, in which a specific WUR is used to trigger the wake-up of main data radio. Proposed analytical energy efficiency model enables to compare the GWR-MAC based WBAN energy consumption with the duty cycle radio based approach. Results clearly show the GWR-MAC potential to improve the energy efficiency of IR-UWB based WBAN.
