only join through the wireless network and interact while he is mov-
ing around. The available choices of wireless network include GPRS,
3G, WiMAX, WiFi, and so forth. Due to the fragility of the wireless
signal while the user is moving, the issue is how to keep a logical
link between the mobile player and the server alive while the signal
strength is still within an acceptable threshold. However, this chap-
ter does not concentrate on the network technologies of any specific
wireless network, but only the logical linking problem is explored.
The MSS periodically detects the connecting status to re-login the
mobile player or dead reckoning missing data.
Data filtration: The mobile player uses a mobile device, such as a
notebook or a wearable computer, to navigate the 3-D virtual space.
Due to the limitation of power consumption, the mobile computer
has inferior computing resources and insufficient network band-
width. For this reason, the issue focuses on how to filter messages
to reduce the computing load of the mobile device. To achieve this
purpose, part of rendering related computing work is shifted to
the MSS, such as the visibility of objects, the level of detail of object
appearance, and the realism of object animation.
Data mediation: Since the mobile player uses the location sensing
device (such as GPS) to navigate the virtual world and animate his
remote avatar, this location information has to be converted into the
