The integration of heterogeneous wireless networks has been studied for some time. Wireless networks can be complementary by providing additional resources to one another if properly integrated. For example, 3G networks offer increased coverage, but they have a low capacity for data transmission. In contrast, WLANs (Wireless Local Networks) offer a limited coverage range while allowing high rates...
Along with the rapid development of 3rd generation mobile communication technologies, the applications of M-Commerce have been greatly expanded. Based on the research and analysis of the J2ME platform, this paper proposes a secure architecture for M-Commerce systems under the 3G networks. The proposed solution is the combination of J2EE and J2ME capabilities based on the three-tier architecture, as...
As heterogeneous wireless networks are deployed and users need more flexible mobility services, there has been a lot of research work about interworking mechanism between widely deployed 3G network and rapidly boarded WLAN. On the other side, WiBro is newly commercialized in Korea as the next generation wireless network. WiBro is based on IEEE 802.16e and it is expected to provide enough mobility...
