Increasing demand for high data rate applications, such as multimedia services and mobile TV over wireless ad hoc networks, urges researchers to develop more flexible network protocols in order to meet various Quality of Service (QoS) requirements. Unfortunately, the traditional strict layering design approach is no longer effective in wireless ad hoc networks, particularly in the mobile ad hoc networks, and fails to achieve the desired flexibility. Thus, cross-layer network design becomes much more important than ever and should be investigated thoroughly. In this project, the PI carefully selects three research tasks ? joint design of flow/congestion control and medium access control, active collaborative relaying, and opportunistic medium access control and auto rate control ? to demonstrate how cross-layer design should be done and how this design could improve the performance. In all these problems, the medium access control (MAC) layer acts as the anchor point to extract the needed information about the wireless environment to be used for other layers. In so doing, network protocols can be made more adaptive and responsive. It is expected that cross-layer design methodology can be significantly advanced through this research. Moreover, the basic ideas and the cross-layer design methodology introduced in this research open a new avenue to the design of efficient network protocols and the proposed technologies could be easily incorporated into the commercial products, and hence will have significant economic impact on the telecommunication industries. Finally, any research outcome of cross-layer design can be easily incorporated into wireless network courses that train the future work force.

对高数据速率应用（例如通过无线自组织网络的多媒体服务和移动电视）的需求不断增长，促使研究人员开发更灵活的网络协议，以满足各种服务质量（QoS）要求。不幸的是，传统的严格分层设计方法在无线自组织网络中，特别是在移动自组织网络中不再有效，并且无法实现期望的灵活性。因此，跨层网络设计变得比以往任何时候都更加重要，应该进行彻底的研究。在这个项目中，PI精心选择了三个研究任务？流量/拥塞控制和介质访问控制、主动协作中继、机会性介质访问控制和自动速率控制的联合设计 ?演示如何进行跨层设计以及该设计如何提高性能。 在所有这些问题中，媒体访问控制（MAC）层充当锚点来提取有关无线环境的所需信息以供其他层使用。这样做可以使网络协议更具适应性和响应能力。预计通过这项研究可以显着推进跨层设计方法。此外，本研究中引入的基本思想和跨层设计方法为高效网络协议的设计开辟了一条新途径，所提出的技术可以很容易地融入到商业产品中，因此将对电信行业产生重大的经济影响。最后，跨层设计的任何研究成果都可以轻松地纳入培训未来劳动力的无线网络课程中。
