Herein, we propose a novel scheme that combines information exchange and user activities in real-time so that those users can integrate their communications seamlessly with their daily lives. Called the Real-Spatial Information-Based Group Communication (r-Space) system, this scheme creates r-Space groups by considering personal and location information and enables users to share information within those groups. In a conventional message sharing scheme, when a user sends a data to other group members, multicast is normally used for the data delivery. However, because multicast does not have a mechanism to ensure the delivery of lost packets, the message may not be able to reach all of its intended recipients. With that point in mind, this paper proposes a reliable data delivery scheme that can improve packet delivery ratios and reduce transmission delays for r-Space communication. Later, we will evaluate this scheme via simulation.
