Almost all distributed virtual environments (DVEs) have been implemented on high-speed wired network. In this study, we have explored a new approach to realize DVEs on wireless mobile network. We designed and developed a set of elemental functions to realize DVEs on the wireless network with fixed transmission delays. Then, a collaborative 3D modeling system allowing remote users to cooperatively create various 3D models on the network is implemented based on the basic functions. This study has produced the following results :1. The DVE architecture for wireless network is designed. It defines a new protocol for each participating host to autonomously control transmission and visualization of update information to realize DVEs on the wireless network.2. The 3D data sharing method based on functional representation to enable transmission and sharing of huge 3D data between remote systems on the network is invented It provides some enhanced functions such as progressive and difference value transmission strategies for the shared data based on the functional 3D model representation.3. The Collaborative design system using interactive evolutionary computation (IEC) is developed. It allows the remote users to collaboratively create new 3D shapes. The system assists the users to easily externalize their unshaped images to some concrete 3D models by employing the IEC framework.4. The application systems aimed at urban planning, civil engineering work management, and production of fireworks animation are implemented to comprehensively evaluate the above three functions.These results are published in IEEE/ACM conference papers and IPSJ/IEICE journal papers. We also apply for a patent about a part of them.

几乎所有分布式虚拟环境（DVE）都是在高速有线网络上实现的。在本研究中，我们探索了一种在无线移动网络上实现 DVE 的新方法。我们设计并开发了一组基本功能，以在具有固定传输延迟的无线网络上实现 DVE。然后，在基本功能的基础上，实现了一个协作3D建模系统，允许远程用户在网络上协作创建各种3D模型。本研究取得了以下成果： 1．设计了无线网络的DVE架构。它为每个参与主机定义了一个新的协议来自主控制更新信息的传输和可视化，从而在无线网络上实现DVE。 2．发明了基于功能表示的3D数据共享方法，能够在网络上的远程系统之间传输和共享庞大的3D数据。它为基于功能3D模型表示的共享数据提供了一些增强功能，例如渐进式和差值传输策略。 3．开发了使用交互式进化计算（IEC）的协同设计系统。它允许远程用户协作创建新的 3D 形状。该系统通过采用IEC框架帮助用户轻松地将其未成形图像外化为一些具体的3D模型。4．实现了针对城市规划、土木工程作业管理、烟花动画制作等方面的应用系统，对上述三项功能进行综合评价。相关成果发表在IEEE/ACM会议论文和IPSJ/IEICE期刊论文中。我们还为其中的一部分申请了专利。
