Research Abstract

With the development and wide spread of diverse wireless network technologies, such as wireless local area network (WLAN) and WiMAX, they will be the underlying basis of heterogeneous networks. In the heterogeneous networks, mobile stations can access the Internet at anytime and anywhere, but they cannot seamlessly move between the individual wireless networks. In this study, we proposed handover management methods to maintain communication quality during their movement, and showed the effectiveness of our proposed methods through simulation and experimental results.
