HIBERNATION SUPPORT FOR WI-FI DIRECT

Abstract

Wi-Fi Direct is 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. 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. Lower power consumption means lower heat dissipation, which increases system stability, and less energy use, which saves money and reduces the impact on the environment. For mobile device and embedded system device, it’s much more important because the battery power is very limited. Nowadays, android phone and iPhone are more and more pervasive. There are more and more sensors and I/O in mobile device that can be used to improve the effectiveness of PM. 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 Implement Hibernate Mode in Wi-Fi Direct to analyse its effectiveness.
