A Novel Resource Management Scheme for Integrated Multiple Traffic Heterogeneous Systems

The next generation wireless network system will be an integration of heterogeneous wireless networks. On the other hand, the future terminals will be equipped with multiple radio interfaces that can access different types of networks. Therefore, the terminals can roam and switch among different types of networks based on their service requirements. With the terminals receiving multiple services and doing vertical handoffs between two different types of networks, how to effectively manage the resources of different types of networks for a better entire system performance has imposed a great challenge for the next generation wireless network. Most of the previous works on this issue discussed the resource management with single type of traffic, while few works have considered the multiple traffic in a heterogeneous network environment. In this paper, we consider multiple traffic with different priorities, and propose a novel resource (or channel) allocation scheme. The proposed system is evaluated through extensive simulations and the results show that the proposed scheme can significantly improve the system performance.
