移动互联网:终端、网络与服务

Mobile Internet: Terminal Devices,Networks and Services

随着宽带无线接入技术和移动终端技术的飞速发展,人们迫切希望能够随时随地乃至在移动过程中都能方便地从互联网获取信息和服务,移动互联网应运而生并迅猛发展.然而,移动互联网在移动终端、接入网络、应用服务、安全与隐私保护等方面还面临着一系列的挑战.其基础理论与关键技术的研究,对于国家信息产业整体发展具有重要的现实意义.文中从移动终端、接入网络、应用服务及安全与隐私保护4个方面对移动互联网的研究进展进行阐述与分析,并介绍了作者在WLAN基站原型系统及无线Mesh网络性能优化方面的研究工作.最后对未来的研究方向进行展望.

The technologies for wireless broadband access and mobile devices have been changing very fast.People expect that information and services can be delivered from the Internet anytime and anywhere even while they are moving.Under the current circumstances,the Mobile Internet becomes an emerging technology and expects to grow up in an accelerated pace.The challenges we are facing from the Mobile Internet come from the mobile devices,access networks,services and security and privacy protection.It is essential for us to further explore the fundamental theories and key technologies to meet the requirements from our national information industry and broad research communities.We conduct a survey of the Mobile Internet on four aspects,namely mobile devices,access networks,services and security and privacy protection.We further give our research on test-bed of WLAN base station and performance optimization of wireless mesh networks.Finally we conclude the paper by elaborating the future research directions on the Mobile Internet.
