摘 要：A theoretical study on the impact of using a wake-up radio architecture in terms of energy consumption is proposed. The main objective is to reduce the overall energy consumption of a home multimedia networks. The energy consumed by the proposed wake-up radio architecture is compared to a classical WiFi architecture, for an ad-hoc scenario. The sleep time has an important role to compare the dissipated energy. This study demonstrates that the longer the sleep time the better the energy saved is obtained by the wake-up architecture.
