无线网络最优接入的研究

随着科学技来的不断发展,各种类型的无线接入技术在全球纷纷涌现并被广泛使用.但是虽然用户可以有很多无装网络可以接入,但是用户很少知道他们运行某一应用程序时哪种接入网络对他们来说是最合适的,由此无线网络的最优接入也成了目前最热门的研究之一.本文通过对无线网络的研究提出了一个适用于无线网络的最优接入架构,该架构由四部分组成,分则是：无线网络最优接入服务器、无线网络侦测器、最优网络接入决策器和用户应用判别器.在介绍完架构的功能后,本文对架构所能实现的部分功能进行了性能测试,通过实验,可以发现架构能够较好的选择出最合适用户的接入网络.

Research on Optimal Access Wireless Networks

With the development of scientific technology, various kinds of wireless access technologies have emerged and been widely used all over the world. Although the users can have a great deal of choices to choose the services from multiple access technologies, most of them can＇t know which service is the best for them when they decide to use the application. So access selection in Always Best Connected network has become one of the most popular researches recently. This paper designs the architecture of wireless network access for the purpose of Always Best Connected network. The architecture is composed of Always Best Connected Server, Always Best Connected Network Detector, Always Best Connected Network Optimizer and User Application Discriminator. After introducing the functions of the architecture and its components, the paper demonstrates the performance test of part of architecture functions. The result shows the architecture can help people to access the best wireless network for them.
