Implementation of Resource Integration and Application of Grouped Mobile Devices Using Wi-Fi Direct

Following the constant improvements in technology and rapid developments in the computers, communications, and consumer electronics (3C) industry, mobile devices have become assistive tools for everyday life. They are lightweight, thin, and convenient for carry and their functionality is akin to a portable computer. However, these devices are normally equipped with small displays. At times when a larger screen is needed, such as when sharing information, watching videos, or discussing in groups of people, the physical device must be passed between all members in the group. Therefore, this study proposes a convenient way to integrate the resources, including display, computation, communication, etc., of multiple mobile devices to create a portable cloud for various applications. This study focused on display integration, combining multiple device screens into one large screen for data display, interaction, and sharing in meetings, for entertainment, or at school. The screens of mobile devices in different locations can also be integrated to create a dynamic billboard. This study also incorporated near field communication (NFC) to share data from one device with all other integrated devices. Wi-Fi Direct was used for group device communication to eliminate the need of Internet connection.
