DirectSpace: A Collaborative Framework for Supporting Group Workspaces over Wi-Fi Direct

Wi-Fi Direct is a new feature in the 4.0 version of the Android operating system, allowing devices to connect directly to each other via Wi-Fi without an intermediate access point. Based on the Wi-Fi Direct feature, in this paper, we present a collaborative framework named DirectSpace that supports various collaborative situations to resolve the problems of traditional application paradigm such as client-server model. For this, we design collaborative services to support various environments, and develop collaborative protocols for providing workspaces over Wi-Fi Direct. On the top of DirectSpace, we also present a collaborative application for utilizing the group workspaces.
