Wi-Fi Direct is a new technology defined by the Wi-Fi Alliance in order to enable efficient device-to-device communication. Portable devices are a main target of this technology and hence, power saving is a key objective. In this paper we analyze the power saving protocols defined in Wi-Fi Direct and design two algorithms to efficiently use them: Adaptive Single Presence Period (ASPP) and Adaptive Multiple Presence Periods (AMPP). Operating only with layer two information, our proposed algorithms allow Wi-Fi Direct mobile devices to address the trade-off between performance and energy consumption in a configurable manner when offering access to an external network. The two algorithms presented, ASPP and AMPP, are evaluated by OPNET simulations.
