A Smart, Reliable and Green Communication System for Emergency Communications

公共安全通信（PSC）系统目前是一个主要因素，作为从灾难性情况中恢复努力的支持因素。它们是在公共基础设施遭到严重破坏后，使人们，特别是应急人员保持联系的手段。对于PSC系统来说，具有可靠性、适应性、可扩展性和可达性是至关重要的。这些综合特性带来了一些技术挑战，因此涉及几个领域的研究机会。由这些因素产生的解决办法的综合应构成一种强有力和持久的解决办法，在混乱的灾难局势占上风之后，可以依靠这种办法恢复正常情况。为了满足这些需求，我们提出了一个具有以下特点的解决方案：独立于现有的基础设施。2. 完整的冗余。3. 绿色行动。4. 易于部署、安装和升级。5. 安全操作。所提出的系统架构为现有移动通信基础设施的覆盖或并行系统。它不是一个细胞系统。相反，它是一个低功耗系统，能够覆盖数十公里以上的通信。该系统还可以通过无人机等自主系统进行增强，用于填补重要的通信空白。这种系统最有力的竞争者是低功耗广域网（LPWAN）技术。该体系结构的元素可以总结如下：-LPWAN网关：这些网关应部署在战略位置，以确保在出现任何故障情况时其安全性和生存性-LPWAN服务器：作为管理整个操作的后端。-基于能量收集的电源：最初可以从电网或其他来源充电，然后依靠周围环境来补充日益减少的供应，随着时间的推移-无线充电元件和链接：这些将使网关通过远程安装的基于能量收集的电源充电继续正常运行-网关安装的无人机用于填补固定网关的通信空白，当需要时，无人机可以战略性地定位以取代高干扰或高碰撞率的网关。提出的算法，协议和方案将使用计算机模拟，分析方法和实验工作进行分析。这三种方法将相互补充和验证。研究结果对突发事件中的公共安全沟通具有重要意义。此外，这项研究将使许多研究人员、研究生和本科生在先进技术和顶尖研究方面得到培训。

Public safety communication (PSC) systems present a major factor nowadays as a support element in the efforts to recover from disastrous situations. They are the means that keep people, especially emergency personnel, connected after the public infrastructure has been stricken in such a way that renders it dysfunctional. It is crucial for the PSC system to have the Reliability, Adaptability, and Scalability and reachability These combined characteristics introduce some technical challenges and hence research opportunities that touch several areas. The integration of the solutions that result from these elements should constitute a robust and long lasting solution that can be relied on to restore the normal conditions after the chaotic disaster situation has prevailed. In order to address these requirements, we propose a solution that has the following features: 1. Independence from existing infrastructure. 2. Complete redundancy. 3. Green operation. 4. Ease of deployment, installation and upgrade. 5. Secure operation. The proposed system is architected as an overlay or a parallel system to the existing mobile communication infrastructure. It is not a cellular system. Rather, it is a low power system that is able to cover communications over tens of kilometers. The system can also be augmented with autonomous systems, e.g. drones, that would be used to fill important communication gaps. The strongest contender for such a system is the low power WAN (LPWAN) technology. The elements of the architecture can be summarized as follows: -LPWAN gateways: these should be deployed in strategic locations in such a way that ensures their safety and survivability should any trouble conditions arise -LPWAN servers: as the backend for managing the whole operation. -Energy-harvesting-based power sources: can be initially charged from the grid or other sources then rely on the ambient environment for the replenishment of the dwindling supply, as time passes -Wireless charging elements and links: these will enable the gateways to continue to function normally via charging from the remotely installed energy-harvesting-based power sources -Gateway-mounted-drones: used to fill the communication gaps with the fixed gateways, when needed Drones can be strategically located to replace gateways that experience high interference or high collision rate The proposed algorithms, protocols and schemes will be analyzed using computer simulation, analytical methods and experimental work. The three approaches will be employed to complement and verify each other. Results from this research are crucial for public safety communication during emergencies. In addition, this research will enable the training of many researchers, postgraduate and undergraduate students in advanced technologies and top notch research.
