Mobile IP performance and interworking architecture in 802.11 WLAN/cdma2000 networks

IEEE 802.11 WLAN is designed to provide high data speed in a small coverage area. 2.5G/3G networks, on the other hand, are intended to offer ubiquitous connectivity with relatively low data speed over a wide area. Accordingly, these two technologies can be viewed as a complement to each other. However, for complementary service, the two access networks have to be integrated and the service provided by both should be transparent to users. Consequently, one of the main challenges is to provide seamless roaming between them that can meet service requirements. Mobile IP (MoIP) has been considered as the most suitable candidate for achieving seamless roaming. We investigate interworking architecture between 802.11 WLAN and 2.5/3G CDMA cellular networks with emphasis on the performance of MoIP. A test bed system has been used and results are presented.
