Although a lot of resource management schemes have been proposed to support multiple traffic in wireless networks, they mostly focused on a single wireless network, such as cellular network. In order to provide more comprehensive services, an integrated wireless network is introduced which consists of several different types of wireless networks and provides more connection options for mobile users than a single wireless network. However, it also imposes a great challenge to efficiently utilize the resources, where existing resource management schemes may not be suitable. In this paper, we propose two resource management schemes to support multiple traffic in an integrated wireless network. In these two schemes, higher priority traffic can preempt lower priority traffic. The system performances are evaluated and compared with one existing scheme by extensive simulations. The simulation results show that the proposed schemes can significantly improve the system performances.
