Nowadays wireless local area networks (WLANs) are widely deployed to provide internet access. Even at home, the number of devices to be connected to the internet increases and consequently the energy consumption of the home multimedia network grows. The necessity to reduce the energy consumption of the connected devices is an ongoing challenge for researchers in order to develop a green home wireless network.
The main goal is to reduce the total energy consumption of a home multimedia network by switching off the data module of each equipment during the periods when it is not used. The wake-up receiver is designed to be able to detect a wake-up signal which has a frequency signature and so, it is avoided to activate all data interfaces but only the one of interest.
