A Semantic Caching Service for Wireless Network Centric Environments

无线通信技术的快速发展及其对日常生活的影响在过去几年中大大增加。但是，传统的客户机/服务器体系结构（客户机完全依赖于服务器获取信息）在无线环境中并不适用，因为服务器通常因为未连接而无法访问。该方案着眼于无线通信技术的发展，并计划设计、开发和实现一个“客户端/代理/服务器系统”，其中客户端代理在断开连接期间承担本地服务器的角色。初步工作表明，该方法在改善数据访问、计算和服务方面具有很大的潜力。目标应用领域包括远程学习、快速移动互联网以及第三代和第四代无线蜂窝网络。

The rapid development of wireless communications technologies and their impact on everyday life has greatly increased over the last couple of years. But, the traditional client/server architecture, where the client relies completely on the server for information, is not useful in the wireless environment, as the server is often not reachable because it is not connected.The proposal focuses on the development of wireless communications technologies and plans to design, develop and implement a "client/proxy/server system" in which a client-side proxy assumes the role of a local server during the disconnections. Preliminary work shows that the approach has great potential to improve data access, computation and service. The targeted application areas include distance learning, fast mobile Internet as well as 3rd and 4th generation wireless cellular networks.
