大规模分布虚拟环境的分级兴趣管理

Hierarchical Interest Management in Large Scale Distributed Virtual Environment

大规模分布虚拟环境中 ,兴趣管理技术使其中的实体只向对它感兴趣的实体发送数据 ,大幅度减少了系统的网络通信开销及计算开销 .然而由于参与分布交互仿真的实体兴趣域的巨大差异 ,可能导致网络通信负载的极度不平衡 ,由此提出了分级兴趣管理技术 .分级兴趣管理技术把兴趣域内实体根据兴趣度分级 ,在此基础上 ,对低兴趣度实体提出了高效的状态数据包压缩、还原算法 ,并提出多阈值 DR技术 ,以减少通信频率 .

The technology of interest management makes the large scale distributed virtual environment only send data of interesting entities, so that the cost of communication and computation is reduced greatly. But the large differences among the interesting domains of objects in distributed interactive simulation cause much unbalance in communication loads, we present the technique of hierarchical interest management which classifies the entities in interesting domains according to their degree of interest. For the entities of lower interest, two measures involving compressing the data packages and lowering the frequency of communication are taken to reduce the volume of communication, which could help solving the problem of unbalance in communication loads.
