Mobile data traffic has dramatically increased in recent years with the emergence of smart devices. Device-to-Device (D2D) communications are expected to become a key feature supported by next generation cellular networks with advantages of: 1) extended coverage; 2) offloading in cellular networks; 3) improved energy efficiency; 4) enhanced throughput and spectrum efficiency; and 5) creation of new services. Interference management is of key importance for deployment of D2D networks. Although D2D communications bring improvement in spectral efficiency and system capacity, it also causes interference to the cellular network as a result of spectrum sharing. Thus, efficient resource allocation and interference coordination must be addressed to guarantee a target performance level of the cellular communications. This project constructs a distributed and cross-layer framework to turn the interference challenges into dynamic resource allocation auspice. The fundamental results to be obtained from this project will enable transformative techniques that can lead to improved performance of the next generation wireless networks. The results will be publicly available through publications and open source software release. The research results will be integrated into the existing combined education and research effort. Furthermore, the education component will equip both undergraduate and graduate students with the skills needed to contribute to the field of wireless networking. Outreach activities will be directed to high school students and increase the participation of women and minority in science and engineering. As such, the broader impact resulting from the proposed activities is also reflected through the integration of research and education for the training of future wireless workforce.The proposed activities are primarily targeted at constructing the new D2D networks, and then uncovering the design challenges, tradeoffs, and requirements for cross layer resource allocation approaches. Major intellectual merits in our proposed research thrusts are: 1) Resource Allocation with Underlay D2D Communication in Cellular Networks: Innovative resource allocation schemes are proposed to maximize the overall network throughput while ensuring quality-of-service. The proposed schemes consist of techniques, such as admission control, power control, and matching potential D2D partners, and then conduct joint cross-layer optimization for both D2D users and cellular users. 2) Game Theoretical Distributed Scheme: A variety of game theory approaches, such as reverse iterative combinatorial auction and Stackelberg game, are adopted for dynamic opportunistic resource allocation. Furthermore, the equilibrium of the game is investigated, and the approaches are designed for the game equilibria to be close-optimal compared to the optimal solutions. 3) Joint Consideration with Femtocell: Since femtocell/smallcell networking and D2D networking are two major research directions pushed by cellular service providers, open access is designed for femtocell together with D2D LTE-Advanced networks in order to optimize network connectivity, coverage, system performance, and balance. 4) Context Aware Network: a context aware framework is optimized for resource management in D2D networks, which is aligned with LTE-direct. Ultimately, the proposed interdisciplinary and cross layer framework will provide a blueprint towards building new perspectives on future wireless network design.

近年来，随着智能设备的出现，移动数据流量急剧增加。设备到设备（D2D）通信预计将成为下一代蜂窝网络支持的关键功能，具有以下优点：1）扩展覆盖范围； 2) 蜂窝网络中的卸载； 3）提高能源效率； 4) 增强的吞吐量和频谱效率； 5) 创建新服务。干扰管理对于 D2D 网络的部署至关重要。尽管D2D通信带来了频谱效率和系统容量的提高，但也由于频谱共享而对蜂窝网络造成干扰。因此，必须解决有效的资源分配和干扰协调的问题，以保证蜂窝通信的目标性能水平。 该项目构建了一个分布式跨层框架，将干扰挑战转化为动态资源分配支持。该项目获得的基本成果将实现变革性技术，从而提高下一代无线网络的性能。结果将通过出版物和开源软件发布公开。研究成果将被纳入现有的联合教育和研究工作中。此外，教育部分将为本科生和研究生提供为无线网络领域做出贡献所需的技能。外展活动将针对高中生，并增加妇女和少数族裔对科学和工程的参与。因此，拟议活动产生的更广泛影响也通过将研究和教育相结合来培训未来无线劳动力来体现。拟议活动主要旨在构建新的 D2D 网络，然后揭示设计挑战、权衡，以及跨层资源分配方法的要求。我们提出的研究重点的主要智力优点是： 1）蜂窝网络中底层 D2D 通信的资源分配：提出了创新的资源分配方案，以最大限度地提高整体网络吞吐量，同时确保服务质量。所提出的方案包括准入控制、功率控制和匹配潜在D2D伙伴等技术，然后对D2D用户和蜂窝用户进行联合跨层优化。 2）博弈论分布式方案：采用反向迭代组合拍卖和Stackelberg博弈等多种博弈论方法进行动态机会性资源分配。此外，还研究了博弈的均衡，并设计了使博弈均衡与最优解相比接近最优的方法。 3）与Femtocell的共同考虑：由于femtocell/smallcell网络和D2D网络是蜂窝服务提供商推动的两个主要研究方向，因此开放接入是为femtocell与D2D LTE-Advanced网络一起设计的，以优化网络连接、覆盖、系统性能和平衡。 4) 上下文感知网络：上下文感知框架针对 D2D 网络中的资源管理进行了优化，与 LTE-direct 保持一致。最终，所提出的跨学科和跨层框架将为构建未来无线网络设计的新视角提供蓝图。
