An Overview of Emergency Communication Networks

Abstract

In recent years, major natural disasters and public safety accidents have frequently occurred worldwide. In order to deal with various disasters and accidents using rapidly deployable, reliable, efficient, and stable emergency communication networks, all countries in the world are strengthening and improving emergency communication network construction and related technology research. Motivated by these situations, in this paper, we provide a state-of-the-art survey of the current situation and development of emergency communication networks. In this detailed investigation, our primary focus is the extensive discussion of emergency communication network technology, including satellite networks, ad hoc networks, cellular networks, and wireless private networks. Then, we explore and analyze the networks currently applied in emergency rescue, such as the 370M narrowband private network, broadband cluster network, and 5G constellation plan. We propose a broadband-narrowband integrated emergency communication network to provide an effective solution for visual dispatch of emergency rescue services. The main findings derived from the comprehensive survey on the emergency communication network are then summarized, and possible research challenges are noted. Lastly, we complete this survey by shedding new light on future directions for the emergency communication network. In the future, the emergency network will develop in the direction of intelligence, integration, popularization, and lower cost, and space-air-ground-sea integrated networks. This survey provides a reference basis for the construction of networks to mitigate major natural disasters and public safety accidents.

Healthcare and successive natural disasters: Lessons still to be learned

“…These updates should ensure the establishment of protected and targeted cellular communication pipelines for first responders, critical health infrastructure, and public notifications during large disaster responses, through cellular, satellite, and unmanned aerial vehicles bandwidths. 14-16…”

“…These updates should ensure the establishment of protected and targeted cellular communication pipelines for first responders, critical health infrastructure, and public notifications during large disaster responses, through cellular, satellite, and unmanned aerial vehicles bandwidths. [14][15][16] Implementing such dedicated communication channels will be vital in ensuring that healthcare providers and emergency responders can maintain the flow of essential information, thereby significantly enhancing the overall effectiveness of disaster response.…”

Energy efficient optimal deployment of industrial wireless mesh networks using transient trigonometric Harris Hawks optimizer

“…Wireless Mesh Networks (WMNs) have emerged as a promising solution for providing ubiquitous and high-speed connectivity in various domains, ranging from urban environments to rural areas [1] . These networks consist of interconnected mesh nodes that collaborate to relay data and extend the coverage area.…”

Urban disaster prevention radio system [1] Moreover, video transmission in urban disaster management systems faces challenges due to limited network infrastructure [6], bandwidth constraints [7], line-of-sight obstructions [8], mobility in dynamic environments [9], and signal interference [10]. These challenges can hinder reliable and timely video transmission, impacting communication and coordination efforts during disasters.…”
