A Smart IoT-Aware System For Crisis Scenario Management

Abstract

Abstract-In most dangerous events, involving many people in large buildings, rescue workers need to intervene in a timely and targeted manner in order to help most number of people and secure the environments without wasting resources. This work presents an Internet of Things(IoT)-based framework, aiming at monitoring environmental parameters in order to alert rescuers when they exceed some alarm thresholds. A hardware infrastructure driven by a software layer adds flexibility and adaptability to the Complex Event Processing engine and to a rule engine-based reflective middleware that manages and analyzes raw data in conjunction with a knowledge base modeling the application domain.

Location Based Indoor and Outdoor Lightweight Activity Recognition System

“…These reasons motivate the research conducted to predict users' behavior and recognize their current and future activities [8][9][10][11][12]. As demonstrated by the various works presented in the literature, thanks to such predictions it is possible to enhance a multitude of existing services, such as improving logistics in different domains [13][14][15], reimagine and dynamically repurpose built environment or customize services [16,17], prevent and manage dangerous situations [18][19][20][21][22], but also their provision. Related to this last aspect, the works proposed in [23,24] demonstrate how the prediction of the user behavior and activities could help in predicting and consequently mitigate the resource demand in a particular moment to distribute the network bandwidth and the processor load dedicated to that service.…”

MQTT-Auth: a Token-based Solution to Endow MQTT with Authentication and Authorization Capabilities

“…The solution we propose has been successfully implemented and its source code is available at the project web page 4 . This implementation, based on Apache ActiveMQ as messageoriented middleware, exploits one of the most popular and powerful open source Message and Integration Patterns server written in Java.…”

“…Examples of these may encompass attacks aiming to exhaust the energy of nodes, such as unsolicited communications from spamming nodes [2], or to manipulate the network such as the intrusion of malicious nodes [3]. However, some of the most dangerous are the large Distributed Denial of Service (DDoS) attacks that have taken place in the last years, with unprecedented volumes of data used to knock-down various Internet services across the world, and that could interfere with important services provided by the Internet of Things, such as alerting in crisis scenarios [4]. The attack performed by the Mirai malware in 2016 [5], specifically designed to attack and hijack IoT devices and to transform them into bots, exploitable to carry out subsequent coordinated attacks, was only the first sign of a still active threat [6].…”

Optimizing the Personnel Position Monitoring System Using the Global Positioning System in Hostage Release

“…Amid an emergency such as a natural disaster or rescue incident, timeliness and accuracy of information regarding the location of rescue team members can make the real difference between safety and danger, between life and death [3]. However, in its implementation, the upper command has limitations in monitoring and supervising location personnel sent to the field [4]. So, we need a system that can monitor the position and location of these personnel [5], [6].…”
