    In the modern era, Disaster Management has become an important field of study. With the advent of telecommunication system and their possible integration with the existing disaster management system, it is possible to minimize the after effects of disaster. In this paper we present a study of available and possible disaster management system based on wireless mobile telecommunication. In order to use such a system in the actual world security requirements such as availability, accountability, integrity and confidentiality must be ensured by the disaster management system

    An overview of emergency communication networks

    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

    SOS Message Distribution for Searching Disaster Victims

    Get PDF
    This chapter presents the design and implementation of the SOSCast application which enables SOS message distribution for searching victims in a disaster-damaged area. During catastrophic disasters such an earthquake or tsunami, people may be injured or trapped in fallen buildings and debris. In situations like these, it is critical that rescue operations must be done within the first 72 h to save many lives. It is also during these events where communication infrastructures are severely damaged, and thus, makes it difficult for victims to ask for help due to the absence of communication channels. By using the SOSCast application in such scenario, victims are able to exchange SOS messages automatically by communicating directly among smartphones with less operation. By collecting these SOS messages, rescuers can find the existences of the victims as mapped on their smartphones. We have shown in our preliminary experiment within a residential area that SOSCast is capable of determining the existence of a propagator based on the collected SOS messages

    The UK government’s Critical National Infrastructure policy for emergency services communications platforms: vulnerabilities in the TETRA architecture

    Get PDF
    In this era of global communications individual communities and entire cities rely heavily on the public telecommunication platforms to support the emergency services workers to provide a professional service in extreme situations, such as natural disasters - floods, earthquakes and hurricanes etc; or terrorist / political attacks, such as London, New York and Madrid. Previous experiences have demonstrated that in such situations entire cities find their general communication platforms such as the Public Switched Telephone Networks and Cellular systems are overwhelmed with emergency communication traffic, as huge number of calls are made locally and internationally to the disaster area to determine if love ones are injured or safe. Until recently under these extreme conditions the emergency services would have to rely solely on the available telecommunications bandwidth and any contingency bandwidth that has been allocated for such situations. However the UK government has a part of its Critical National Infrastructure as deployed a TETRA based private mobile radio (PMR) system to separate critical emergency communication from the general communication platforms. This paper analyzes whether this new system is resilient or could the use of MANET’s be utilised to operate in extreme situations to provide a crucial short/mid-term communication platform

    Designing an Architectural Model of Crisis Management Information System for Natural Disasters in Iran

    Introduction: The crisis management information system (CMIS) is a mission-critical system that enables the crisis management team for understanding, diagnosing, interpreting, analyzing, structuring, and making decisions faster by providing timely and high-quality information at the right time. The purpose of this research is to provide an architectural model of a CMIS for managing natural disasters in the process of finding trapped victims and relieving them. Materials and Methods: This applied study was conducted in 2020 in two stages. First, data on CMIS used in selected countries were collected from electronic resources and digital libraries and were then analyzed. Next, a preliminary model of CMIS architecture including three aspects of informational content, applications, and technological requirements, was prepared using these systems and experts’ interviews. Finally, the architectural model of CMIS validated by the Delphi technique and the focus group. Results: The analysis of experts in three rounds of Delphi test for three aspects of informational content, applications and technological requirements in the architectural model was performed with the presence of experts at the national level and the consensus rate over 75% was obtained for 7 modules and 28 proposed components of the CMIS. Conclusion: The architecture of information systems has a direct impact on the performance of these systems. Using an appropriate architecture for CMIS can be an effective step towards reducing the costs and consequences of crises in Iran and countries with similar conditions and have a significant impact on saving human lives in emergency situations
