QoS Adaptation for Realizing Interaction between Virtual and Real Worlds in Pervasive Network Environment ∗

By Shinya Yamamoto, Yoshihiro Murata, Naoki Shibata, Keiichi Yasumoto and Minoru Ito


We propose a framework called FAIRVIEW which realizes cooperative work and interaction between mobile users in real world and remote network users. FAIRVIEW allows mobile users and network users to share the same view of a shared space including many moving objects in sufficient quality for interaction. For this purpose, we devised a mechanism which continuously measures information (called AR information) of the position and direction of each object and delivers AR information to user terminals, so that users can see moving objects in real-time. In order to realize real-time delivery of AR information with limited network resource in an ordinary wireless LAN and Internet environment, we propose a QoS adaptation mechanism which allows users to observe more important objects with a higher framerate. Through experiments supposing network environments with various available bandwidths, we confirmed that the proposed mechanism achieves a practical framerate of moving objects between mobile users and remote users in pervasive network environment
