Research Of Campus WLAN Authentication And Design Of An Authentication Client

In recent years, with the rapid development of information technology, wireless network and mobile intelligent terminal are very popular in people’s daily life, and people’s life and work are also changed deeply. In campuses, as the majority of pursuing fashion, students have a vast number of smart terminals, so they have an active demand for the campus WLAN. However, the construction of the campus WLAN is not perfect now. There are two disadvantages in it, on one hand, in authentication, Web Portal is widely used in campus WLAN, and it is very complicated. On the other hand, in application, as a solution of Campus Area Network, campus WLAN provide a network environment for schools in daily researching, teaching, working and management, which is very simplex infunction. As a supporter of education informationization and an important content of Smart Campus construction, it is very significant to improve the campus WLAN and enhance its application value.In this paper, we start with the authentication of WLAN, andargument and compare with the major authentications which are often used. Then, the Client Portal has been presented as the best authentication which is used in campus WLAN, and the HTTP packages in the authentication process are analyzed and designed in detail. Then, we realize the client demo in Android OS. After that, we extend the client in socializing function by raising two applications which are chatting room based on the same AP and friend recommendation based on the WLAN traces, then, we design the two applications from system architecture. Finally, we summary our current work and the future work are prospected.
