The evolution of software radio has enabled wireless network devices to dynamically reconfigure their air interfaces. As a result, network protocols and resource management should fully exploit the advantages provided by this flexibility. Although extensive work has been done to enable network reconfiguration at the physical layer, little has been done to study issues related to quality of service (QoS) provisioning and resource management in a network where stations can dynamically reconfigure their air interfaces. In the proposed project we will study important issues in allocating radio resources for supporting multimedia services in reconfigurable wireless networks. The objective of this research is to provide solutions and technologies so that mobile stations can keep their traffic always best connected by dynamic and adaptive reconfigurations, and the precious radio resources can be efficiently utilized. Specifically, we will propose strategies for mobile stations to adaptively select their air interfaces, design admission control and transmission scheduling schemes for networks to effectively support the QoS of multimedia traffic, and provide solutions to ensure smooth connections during and after reconfigurations. The basic approach is to take into consideration both horizontal and vertical information in a reconfigurable network in order to optimize the resource allocation performance, where horizontal information comes from sub-networks using different air interfaces, and vertical information is from different layers of the network protocol stack. The outcomes of this research will contribute towards future always-best-connected networks and benefit network operators, mobile users, and equipment manufacturers. This work will benefit the Canadian telecommunication industry by attracting more investments in wireless networks and encouraging more mobile wireless users.

软件无线电的发展使得无线网络设备能够动态地重新配置其空中接口。因此，网络协议和资源管理应该充分利用这种灵活性所提供的优势。尽管在物理层实现网络重新配置方面已经做了大量的工作，但在研究与网络中的服务质量（QoS）配置和资源管理相关的问题方面却做得很少，在网络中站可以动态地重新配置其空中接口。在拟议的项目中，我们将研究分配无线电资源以支持可重构无线网络中的多媒体服务的重要问题。本研究的目的是提供解决方案和技术，使移动台能够通过动态和自适应重新配置来保持其流量始终处于最佳连接状态，并有效利用宝贵的无线电资源。具体来说，我们将提出移动站自适应选择空中接口的策略，设计网络准入控制和传输调度方案，以有效支持多媒体流量的服务质量，并提供解决方案以确保重新配置期间和之后的平滑连接。 基本方法是在可重构网络中同时考虑水平和垂直信息，以优化资源分配性能，其中水平信息来自使用不同空中接口的子网，垂直信息来自网络协议的不同层堆。 这项研究的成果将为未来始终保持最佳连接的网络做出贡献，并使网络运营商、移动用户和设备制造商受益。这项工作将吸引更多无线网络投资并鼓励更多移动无线用户，从而使加拿大电信业受益。
