The next generation wireless communications systems are envisioned to integrate multiple wireless access technologies (i.e., IEEE 802.11-based WiFi WLAN and IEEE 802.16-based WiMAX WMAN) to provide high-speed communications services to mobile users in a seamless manner. In such a heterogeneous wireless network, the users are able to access different wireless networks according to their preference, performance and cost. In this research, the radio resource management for this integrated heterogeneous wireless network will be proposed. At the mobile terminal, network selection algorithm will be developed to make the decision of connection (either WiFi or WiMAX or both) so that the QoS requirements are satisfied while the connection cost is minimized. An optimization problem will be formulated and solved for an optimal decision. In addition, the applications of this integrated heterogeneous wireless networks in vehicular network and e-Health will be explored.
