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）系统必须向受灾地区的公共安全人员和用户提供高容量的无线服务，而对基础设施的依赖几乎没有。值得注意的是，现代PSC系统尚未赶上过去十年的无线革命，因为它们仍然依靠过去的技术技术，这些技术无法交付高速无线访问。确实，应对未来PSC系统中预见的严格服务要求授权的主要创新可以提高光谱效率。反过来，这需要应对多学科挑战：1）为政府机构，提供者和用户开发激励机制，以分享其宝贵的频谱资源； 2）动态管理相互依存的频谱市场； 3）有效地建模和操作可持续的通信协议，这些协议几乎没有基础架构支持。该项目汇集了无线通信和网络，游戏理论，数学和公共安全管理部门的研究人员，通过引入一个新颖的框架来解决这些挑战，并提高PSC的效率，该框架为在灾难和紧急情况下提供了建模，设计，设计，分析和运营大规模分享的必要分析工具。这项研究的总体科学优点是启动急需的飞跃，向PSC的无线频谱进行更开放，高度参与和普遍的共享。该项目提供了一系列共享创新的范围：1）新的经济方法和PSC机制，这些机制为政府机构，提供商和最终用户提供了激励措施，以有效地补贴稀缺的无线电范围，并促进新颖的公共安全和光谱分配政策； 2）一个基础框架，该框架紧密整合了游戏理论和拍卖理论的工具，以使共同存在的频谱共享市场具有多跳功能的动态操作； 3）在PSC中表征无线通道，流量，拓扑，用户行为和移动性的新颖现实模型； 4）理论结果有效，有效地通过新的PSC测试进行实践，以进行广泛的验证，并与几个主要的行业合作伙伴和当地公共安全机构进行密切合作。简而言之，该项目提供了新一代的PSC系统和协议，以加快对灾难，挽救生命并降低经济成本的反应。
