Research presented in this paper enhances the power management schemes of Wi-Fi Direct to provide better services for a wider range of Wi-Fi Peer-to-peer (P2P) applications. Although the Wi-Fi Direct defines two power management schemes to provide energy efficiency in P2P devices, neither is enough to meet power efficiency and reliability requirements for various services. To alleviate this problem, the proposed scheme recognizes the properties of applications and dynamically adjusts the duty cycle of P2P devices. The proposed scheme is compared with the schemes in Wi-Fi Direct to analyse its effectiveness.
