Abstract

With the development of mobile communication and wireless technology, communication networks become increasingly large, network type and network structure also becomes increasingly complex. The constant introduction of new technology like 3G, WLAN, WIMAX , makes the network more persified. Network must be moving in the heterogeneity and the integration of development in the future. How to achieve the integration of heterogeneous networks to meet different business needs in the current network environment become the focus of research.

Firstly, this paper briefly discusses the topic background and the research content. And then analyze the WIFI and WIMAX, including both the respective characteristics as well as the feasibility of their convergence. After that, this paper introduces the simulation tool called NS3 which is used in the study, mainly describe the function associated with the simulation of NS3. Based on this technical theoretical knowledge, the specific implementation process of integration of WIFI and WIMAX based on the NS3 is given in this paper. Finally, the simulation of the integration of wireless heterogeneous networks is completed and simulation results are analyzed.
