Study Of Heterogeneous Integrated Mechanism In Wireless Networks

In recent years, wireless networks technology especially WLAN, WiMAX, 3G and Mesh, and its application develop rapidly. WLAN, WiMAX and 3G have strong complementary characteristics,and the heterogeneous network integrating technology has been increasingly discussed.This paper mainly explores the heterogeneous integrating mechanism in wireless networks. Based on the analysis of the network security of WiMAX and 3G, we introduce the ideology of hierarchical Moblile IP agent, and synthesize the advantages of loosely coupled integration architecture and tightly coupled integration architecture in heterogeneous network, then put forward an optimized integrating scheme of WiMAX and 3G. Moreover, according to the new requirements of the heterogeneous integrated Network to authentication scheme and related theoretical knowledge of cryptology, a new authentication scheme is put forward, which enables the users to complete their authentication process within their own network covering fields, and thus reaches the aim of self-management, and improves the performance and efficiency of the heterogeneous Integrated Network.Finally, according to the research on the key technologies of wireless Mesh network, the designing scheme of wireless Mesh network system based on WLAN is proposed, which supplies the heterogeneous integrated network with the fundamental facilities of mutual communication. In this paper the designing pattern and systematical structure are analyzed in detail, followed by the elaboration of the implementation of system terminal authentication access model.
