Next-generation public safety communication (PSC) systems must deliver high-capacity wireless services to public safety personnel and users in disaster-affected areas, with little reliance on infrastructure. Remarkably, modern-day PSC systems have yet to catch up with the past decade's wireless revolution, as they still rely on technologies of yesteryears that fall short on delivering high-speed wireless access. Indeed, coping with the foreseen stringent service requirements in future PSC systems mandates major innovations that can increase spectral efficiency. This, in turn, requires tackling multidisciplinary challenges: 1) developing incentive mechanisms for government agencies, providers, and users to share their precious spectrum resources; 2) dynamically managing interdependent spectrum markets; and 3) efficiently modeling and operating sustainable communication protocols that can function with little infrastructure support. This project brings together researchers in wireless communications and networking, game theory, mathematics, and public safety administration to address these challenges and boost the efficiency of PSC by introducing a novel framework that provides the necessary analytical tools for modeling, designing, analyzing, and operating large-scale spectrum sharing in disaster and emergency situations. The overarching scientific merit of this research is to initiate the much-needed leap towards a more open, highly participatory, and pervasive sharing of the wireless spectrum for PSC. This project offers an array of spectrum sharing innovations: 1) new economic approaches and PSC mechanisms that provide incentives for government agencies, providers, and end-users, to effectively subsidize the scarce radio spectrum and facilitate novel public safety and spectrum allocation policies; 2) a foundational framework that tightly integrates tools from game theory and auction theory for enabling a dynamic operation of co-existing spectrum sharing markets with multi-hop capabilities; 3) novel realistic models for characterizing wireless channels, traffic, topology, user behavior, and mobility in PSC; and 4) effective and accelerated transition of theoretical results to practice via a new PSC testbed for extensive validation and close collaboration with several major industry partners and local public safety agencies. In a nutshell, the project provides a new generation of PSC systems and protocols that expedite the response to disasters, save lives, and reduce economic costs.

下一代公共安全通信 (PSC) 系统必须为受灾地区的公共安全人员和用户提供高容量无线服务，并且几乎不依赖基础设施。值得注意的是，现代 PSC 系统尚未赶上过去十年的无线革命，因为它们仍然依赖于过去的技术，而这些技术无法提供高速无线接入。事实上，应对未来 PSC 系统中可预见的严格服务要求需要能够提高频谱效率的重大创新。反过来，这需要应对多学科挑战：1）为政府机构、提供商和用户共享宝贵的频谱资源制定激励机制； 2) 动态管理相互依赖的频谱市场； 3）有效地建模和操作可持续的通信协议，这些协议可以在很少的基础设施支持下运行。该项目汇集了无线通信和网络、博弈论、数学和公共安全管理领域的研究人员，通过引入一种新颖的框架来应对这些挑战并提高 PSC 的效率，该框架为建模、设计、分析和操作提供必要的分析工具灾难和紧急情况下的大规模频谱共享。这项研究的首要科学价值是启动急需的飞跃，实现 PSC 无线频谱的更加开放、高度参与和普遍共享。该项目提供了一系列频谱共享创新：1）新的经济方法和 PSC 机制，为政府机构、提供商和最终用户提供激励，以有效补贴稀缺的无线电频谱并促进新颖的公共安全和频谱分配政策； 2) 紧密集成博弈论和拍卖理论工具的基础框架，以实现具有多跳功能的共存频谱共享市场的动态运行； 3) 用于表征 PSC 中无线信道、流量、拓扑、用户行为和移动性的新颖现实模型； 4) 通过新的 PSC 测试平台进行广泛验证并与几个主要行业合作伙伴和当地公共安全机构密切合作，有效、加速地将理论结果转化为实践。简而言之，该项目提供了新一代的 PSC 系统和协议，可以加快灾难响应、拯救生命并降低经济成本。
