A synchronization mechanism in networked virtual environment

We describe the design of a group synchronization mechanism for a local area network virtual environment and introduce a step synchronization mechanism. We use a football game to evaluate this mechanism. In this football game, users can share a virtual space where they can move around, dribble and shoot. To achieve synchronization among users, a client of the game exchanges data through a server within a certain period time. A problem of such a system is that all users should share the space in the same time for justice competition. But because of the different capacity of computers and the time cost of the communication between clients, it is difficult for all clients to update the virtual space simultaneously. In our systems, we introduce a waiting time synchronization mechanism. To evaluate our proposed architecture and mechanisms, we make a series of experiments in our local area network and then build and analyse the model of our system.
