Abstract
Background/Objectives: When disasters caused by nature occur, for example, floods or earthquakes, it is common for communications infrastructure to collapse, leaving people isolated; which can increase the risk of vulnerability after the disaster, due to ignorance of vital information to receive help. The objective of this work is to provide a mechanism to enable people affected during a disaster to have a communication channel to inform aid entities about their personal condition. Methods: The present work is based on a descriptive methodology that allows representing an architecture that makes it possible to send messages through an ad hoc network generated with mobile devices, which is based on the guides of the 4 + 1 views model. Findings: The work provides a guide that enables connectivity for communication during disaster situations, being of great help, for disaster response agencies, to quickly assist potential victims of disasters, who are in a vulnerable situation. Application/Novelty: The work has allowed us to generate a test scenario where the functionality of the architecture is validated. There has also been a simulated scenario where the behavior of the Ad hoc network is studied, which allows sending help messages in the moments after the occurrence of a natural disaster. Keywords: Adhoc Network, Disaster Relief, Mobile Networks, SOS Messages
Highlights
A natural disaster is defined as an event of nature that threatens and jeopardizes the function and safety of the community
The importance of this work lies in the fact that it allows providing a form of alternative communication for victims in a natural disaster situation and save their lives; this can become a valuable tool for disaster response agencies when seeking victims and helping them, as well as a useful tool to meet communication needs in cases where conventional communication methods do not work
The test scenarios indicate that it is possible to create communication channels independent of the infrastructure that currently exists in a certain area, so that victims can rely on their mobile devices in a disaster situation
Summary
A natural disaster is defined as an event of nature that threatens and jeopardizes the function and safety of the community. When a natural disaster occurs the communications infrastructure usually collapses. This situation does not allow affected people to inform their families or disaster assistance organizations about their state of health or where they are located placing this population in a vulnerable state. The lack of information and communication channels generates noise that increases the potential risk in people after a catastrophic situation has occurred. The above can aggravate the situation, creating confusion in the population, which generates uncertainty, chaos in the moments after the eventuality, problems distribution of resources, problems of public order, congestion in hospitals, saturation of security agencies, among others
