Fire is a terrifying weapon, with nearly unlimited destructive power. Fire accidents are a major
cause of human suffering and material loss and the one that perhaps are predicted the least
accurately. A series of computer vision-based fire detection algorithms is proposed in this paper.
These algorithms can be used in parallel with conventional fire detection systems to reduce false
alarms. The motivation behind this research is to obtain beneficial information from images in the
forest spatial data and use the same in the determination of regions at the risk of fires by utilizing
Image Processing and Artificial Intelligence techniques. The proposed intelligent system will thus
aid in alerting the fire stations with the help of a Global System for Mobile Communications in
event of any fire to take immediate actions before fire spreads quickly and causes traumatizing
loss.

Precision agriculture (PA) is a complete farm management approach that uses and exploits different sources of information at different scales (spatial, temporal and spectral) provided by varied technology (sensors, satellites, UAVs, robots) for improved resource use efficiency, productivity, quality, profitability and sustainability of agricultural production.
One of the common methods used in PA is spectroscopy. It relies in the analysis of the electromagnetic spectrum in the visible and near infrared ranges. Some of the applications are quality check of fruits, meat, and fish, grading and sorting at-harvest applications for fruits and vegetables, soil characterization, health of vegetation for monitoring diseases, and many others.
Traditionally, the instruments used in spectroscopy are costly and oriented to laboratory applications. Also exist field instruments but the limited temporal resolution impacts in the overall analysis of the applications.

Smart Home Management System Using Wireless Sensor Network (WSN)paperpublications3
Abstract: Nowadays, shortage of electricity is a very serious problem due to insufficient production. The wastage of electricity can be avoided by switching off the electrical appliances when not in use. This can be achieved by using Smart home system which automatically turns off loads when not in use, the system can save energy in homes and offices. The system will automatically switch off based on the presence of people at home. Another major issue is that there might be occurrence of theft when nobody is present at home. The theft can be avoided by using MEMS accelerometer which intimates the user through registered mobile number when there is an unexpected break of windows or door through the GSM modem. The system in addition also has a provision for the user to fix energy consumption reading and when the user consumption exceeds a fixed reading, a message would be sent to the users registered mobile number through the GSM modem. Applications for this system include workstations, open office cubicles, home offices, and home entertainment systems.

Wireless sensor networks carry out cooperative activities due to limited resources and nowadays, the applications of these networks are copious, varied and the applications in agriculture are still budding. One interesting purpose is in environmental monitoring and greenhouse control, where the crop conditions such as weather and soil do not depend on natural agents. To control and observe the environmental factors, sensors and actuators are necessary. Under these conditions, these devices must be used to make a distributed measure, scattering sensors all over the greenhouse using distributed clustering mechanism. This paper reveals an initiative of environmental monitoring and greenhouse control using a sensor network.
IoT Based Automatic Gas, Smoke and Fire Alert Systemijtsrd
The goal of this system is to build an IoT based automatic gas, smoke and fire alert system via Node MCU. We use a Node MCU, sensors, a microcontroller system, and a few more electronic devices in the current endeavor. This endeavor has easy to use gas, smoke and fire detection. When people are outside of industries, residences, or marketplaces, they are not automatically informed about sudden events caused by fire, gas, or smoke. Not even fire departments receive the information instantly. People suffer greatly as a result, and most of the time, fire nearly destroys residences, companies, and marketplaces. However, our system may be able to help by automatically alerting concerned people to the presence of smoke, gas and fire. As a result, people will be able to arrive at the location swiftly and act promptly. For the system to obtain the data from the fire, gas and smoke sensors, a microcontroller needs to be installed to control every device involved in this work. Wi Fi shield functions a way to connect devices with the network. This system uses an Android app to retrieve the sensors data. This experiment analyses the rooms performance in various fire, gas, and smoke conditions as well as burning objects. The researchers found that when smoke concentrations rise above 100 parts per million, people may get fatal heart attacks, coughing fits, and stinging eyes. However, when the smoke content hits 40 parts per million, our system will automatically send out an alert message. With the help of our technology, we hope that individuals will be able to save their lives and property. Md. Abdur Rahim | Md.

SUPPORT VECTOR MACHINE-BASED FIRE OUTBREAK DETECTION SYSTEMijscai
This study employed Support Vector Machine (SVM) in the classification and prediction of fire outbreak based on fire outbreak dataset captured from the Fire Outbreak Data Capture Device (FODCD). The fire outbreak data capture device (FODCD) used was developed to capture environmental parameters values used in this work. The FODCD device comprised DHT11 temperature sensor, MQ-2 smoke sensor, LM393 Flame sensor, and ESP8266 Wi-Fi module, connected to Arduino nano v3.0.board. 700 data point were captured using the FODCD device, with 60% of the dataset used for training while 20% was used for testing and validation respectively. The SVM model was evaluated using the True Positive Rate (TPR), False Positive Rate (FPR), Accuracy, Error Rate (ER), Precision, and Recall performance metrics. The performance results show that the SVM algorithm can predict cases of fire outbreak with an accuracy of 80% and a minimal error rate of 0.2%. This system was able to predict cases of fire outbreak with a higher degree of accuracy. It is indicated that the use of sensors to capture real world dataset, and machine learning algorithm such as support vector machine gives a better result to the problem of fire management.
COMPLEX EVENT PROCESSING USING IOT DEVICES BASED ON ARDUINOijccsa
Complex event processing systems have gained importance since recent developments in communication
and integrated circuits technologies. Developers can easily develop many smart space systems by
connecting various sensors to an Arduino as an internet of thing device. These systems are useful for many
places such as factories, greenhouses (plant house) and smart-homes. Especially in plant houses when the
desired humidity, temperature, light and soil moisture drops the certain level, the users should be notified
through their smartphones. The sensor information is sent to a central server over the internet via an
access point. The collected sensor data needs to be processed online to check whether an event is occurred
or not. The event processing system based on a complex event processing tool is created on the central
server. It is also an important issue to inform mobile users whenever an event occurs. A publish-subscribe
event based system is implemented on the central server. A mobile user is subscribed to the desired event
topic. When an event occurred, which is related with a specific topic, an alarm notification is sent to the
mobile users about the event information so as to take necessary precautions.

Design of a prototype for sending fire notifications in homes using fuzzy log...IJECEIAES
This paper highlights the need to address fire monitoring in densely populated urban areas using innovative technology, in particular, the internet of things (IoT). The proposed methodology combines data collection through sensors with instant notifications via text messages and images through the user’s email. This strategy allows a fast and efficient response, with message delivery times varying from 1 to 4 seconds on Internet connections. It was observed that the time to send notifications on 3G networks is three times longer compared to Wi-Fi networks, and in some 3G tests, the connection was interrupted. Therefore, the use of Wi-Fi is recommended to avoid significant delays and possible bandwidth issues. The implementation of fuzzy logic in the ESP32 microcontroller facilitates the identification of critical parameters to classify notifications of possible fires and the sending of evidence through images via email. This approach successfully validated the results of the algorithm by providing end users with detailed emails containing information on temperature, humidity, gas presence and a corresponding image as evidence. Taken together, these findings support the effectiveness and potential of this innovative solution for fire monitoring and prevention in densely populated urban areas.
Development in the technology of sensor such as Micro Electro Mechanical Systems (MEMS), wireless communications, embedded systems, distributed processing and wireless sensor applications have contributed a large transformation in Wireless
Sensor Network (WSN) recently. It assists and improves work performance both in the field of industry and our daily life. Wireless Sensor Network has been widely used in many areas especially for surveillance and monitoring in agriculture and habitat monitoring. Environment monitoring has become an important field of control and protection, providing real-time system and control communication
with the physical world. An intelligent and smart Wireless Sensor Network system can gather and process a large amount of data from the beginning of the monitoring and manage air quality, the conditions of traffic, to weather situations.
WSN Based Temperature Monitoring System for Multiple Locations in Industryijtsrd
Wireless sensor network technology has demonstrated a great potential for industrial, commercial, and consumer applications. Speci cally, in process monitoring and control, process data such as pressure, humidity, temperature, ow, level, viscosity, density and vibration intensity measurements can be collected through sensing units and transferred wirelessly to a control system for operation and management. Adopting WSNs for process monitoring and control provides great advantages over traditional wired system. In today's world we are facing with many di erent types of emergencies in the indoor environment. Response to such emergencies is critical in order to protect resources including human life and also we can save property from damage. This wireless sensor network for Temperature monitoring System which can report the emergency to the users in various forms, such as pop ups on a Computer screen, SMS on their cell phones and so on. Due to this exibility of reporting low cost wireless sensor network prepared for emergency response system of future. We are going to develop three wireless sensor nodes and we have to place in di erent position in the building using arduino board and we have to inform to the master node or monitoring node about the temperature available at each sensor node. While sending data to each and every sensor is very costly. Hence nodes are connected to WSN and their is only one node called 'Gateway' which collects the data from all other nodes and sends it to the cloud.

Development of Personal Weather Report for Home SecurityIOSRJVSP
With the fast growing technology, it is a great need to get to know about our surrounding weather parameters (temperature, humidity, atmospheric pressure, gas and light intensity) for better development of living community. A complete weather report can easily access the rarest and the farthest information at one’s own fingertips. It is based on IoT (Internet of Things), which is an emerging field in which all the devices are connected to a channel and collect the data to gather a complete information through a personnel devices. It is generally used to view the weather parameters with the help of unique API key for a particular user. Wi-Fi module, temperature, pressure, humidity, gas, and light intensity sensors are interfaced with the Arduino. The user is prompted to provide the API key of channel. ESP8266-01 reads the key and sends it to the Arduino. If the key is matched, then the data transmission can be carried out between the channel and the microcontroller. The module is connected to the Wi-Fi through some AT Commands.
With the advancements in wireless technology and digital electronics, some tiny devices have started to be used in numerous areas in daily life. These devices are capable of sensing, computation and communicating. They are generally composed of low power radios, several smart sensors and embedded CPUs (Central Processing Units). These devices are used to form wireless sensor network (WSN) which is necessary to provide sensing services and to monitor environmental conditions. In parallel to WSNs, the idea of internet of things (IoT) is developed where IoT can be defined as an interconnection between identifiable devices within the internet connection in sensing and monitoring processes. This paper presents detailed overview of WSNs. It also assesses the technology and characteristics of WSNs. Moreover, it provides a review of WSN applications and IoT applications.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Abstract: Fires usually occur in homes because of carelessness and changes in environmental
conditions. They cause threats to the residential community and may result in human death
and property damage. Consequently, house fires must be detected early to prevent these types
of threats. The immediate notification of a fire is the most critical issue in domestic fire detection
systems. Fire detection systems using wireless sensor networks sometimes do not detect a fire
as a consequence of sensor failure. Wireless sensor networks (WSN) consist of tiny, cheap, and
low-power sensor devices that have the ability to sense the environment and can provide real-time
fire detection with high accuracy. In this paper, we designed and evaluated a wireless sensor network
using multiple sensors for early detection of house fires. In addition, we used the Global System for
Mobile Communications (GSM) to avoid false alarms. To test the results of our fire detection system,
we simulated a fire in a smart home using the Fire Dynamics Simulator and a language program.
The simulation results showed that our system is able to detect early fire, even when a sensor is not
working, while keeping the energy consumption of the sensors at an acceptable level.

1. Introduction
In recent years, fire detection has become a very big issue, as it has caused severe damage
including the loss of human lives. Sometimes, these incidents are more destructive when the fire
spreads to the surroundings. Early detection of a fire event is an effective way to save lives and reduce
property damage. To escape a fiery place and to douse the fire source, the fire must be detected at its
initial stage. The installation of a fire alarm system is the most convenient way to detect a fire early and
avoid losses. Fire alarms consist of different devices working together that have the ability to detect
fire and alert people through visual and audio appliances. The detection devices (i.e., heat, smoke,
and gas detectors) detect events and activate the alarm automatically, or sometimes the alarms are
activated manually. The alarm may consist of bells, mountable sounders, or horns.
Most of the fire alarm systems use the technology of a wireless sensor network (WSN). WSNs have
gained popularity because they have a variety of uses in different applications, such as target
tracking [1,2], localization [3], healthcare [4,5], Smart Transpiration [6], environmental monitoring, and
industrial automation [7]. WSN is also used in collecting data and monitoring, both autonomously or
with the help of users [8,9]. WSN applications also help human and animals [10,11] and are also used
for industrial purposes, for example, underground pipeline monitoring. In a WSN, sensor devices
are often very tiny, battery-powered, and densely populated with the functionality of monitoring
several parameters of the environment. The sensed data are sent to the main collecting unit (i.e., the

sink, cluster head etc.) for processing [8]. WSNs used for fire detection systems also have the same
functional properties. Each sensor detects rising heat, smoke, or gas in some spots in a home and
generate san alert in its head node in a network. The head node collects reports from various sensors
and identifies the presence of a fire. Next, different heads coordinate the received inputs and consult
with a remote command center to plan a response that may consist in a simple fire alarm generation
or in complicated evacuation methods. Numerous technologies based on WSN have already been
proposed to detect fire. Some of them are stand-alone with WSN, and some have hybrid technologies.
There are many event detection systems, which help to identify heat, gas, and smoke.
Today, smart houses and smart cities are equipped with different type of WSNs [12]. In WSNs,
more energy may be consumed because of communication overhead. Thus, most of the time, a sensor’s
battery is exhausted very fast and it may cause the failure of the sensor or the breakdown of whole
network, as houses have different sub-portions and each portion is equipped with one sensor with
a single function, which in case of failure causes a system flaw. In this scenario, if an event occurs
in a certain portion and the sensor fails to detect the accident, then there is no other way to detect
the incident at its initial stage. As unifunctional sensors are only be able to detect one event, there
is another noticeable issue regarding the possibility of false alarms. For example, a heat detector
detects temperature in the environment and produces the alarm if the temperature increases beyond a
threshold. However, the increase in heat may be due to environmental changes or human activity in
the room. In the case of smoke detectors, the smoke may come from outside or from other sources.
The cost of a false alarm is estimated between $30,000 and $50,000 per incident [13].
Today, sensors are very cheap and very small in size. Thus, to address the above-mentioned
challenges, we propose an efficient, IoT-based intelligent home fire prevention system using multiple
sensors. Each of the sensors uses its own mechanism for detection. Our method detects fire
very efficiently and reduces false positives by using Global System for Mobile Communications.
The contribution of this article is manifold.
• Problems and challenges related to the current approaches are identified. The existing methods use
single sensor for each target regions. Nowadays, sensors are very cheap so we used multi-sensors
for every critical region to address problems linked to single sensor detection.
• We use GSM communication to alert the user at early stages if the sensor reports a fire.
• The identification of the fire is made by the system after verification from two sources.
These sources are: (1) Response of the user to the GSM alert, i.e., if the user response is fire,
then our system directly generates the alarm; (2) When two or more sensors report fire, then the
system directly generates a fire alarm without waiting for the user response.
• We use star topology for the deployment of sensors and communication between sensors and
main home sink. We use the ZigBee protocol to provide communication between the sensors and
the sink.
• Finally, we evaluate the system concerning energy consumption.
The rest of the paper is organized as follows. The related work is presented in Section 2. Section 3
discusses the analysis of fire data. Section 4 describes the overview of our proposed work and the
detailed design of the fire detection system. Simulation details and results are exposed in Sections 5
and 6, respectively. Finally, the article is concluded in Section 7.
2. Related Work
In the last few years, sensors have been widely used for fire detection [14–19]. Silva et al. [14]
proposed a work for fire detection in mines by using wireless sensor networks called WMSS.
For determining the hazardous factor in the mines, they used gas sensors and designed a wireless
sensor network which collects and analyses the gas level in mines. The work proposed in [15] used
Zigbee-based wireless sensors for fire detection in forests. They used temperature sensors to establish
the intensity of fire in a forest. They used a CC2430 chip in their hardware design for network
3. J. Sens. Actuator Netw. 2018, 7, 11 3 of 16
nodes. Similarly, Buratti et al. [16] also designed a framework for forest fire detection. In their
work, they used a model for fire detection using different clustering schemes and communication
protocols. They performed the simulation for validation and evaluation of their work. W. Tan et al. [17]
implemented a work for forest fire detection. They used multi-sensor and wireless IP cameras to
avoid false alarms. Their system also connected to the internet via gateways for uploading the data
to the cloud. A work proposed in [18] for forest fire detection was based on a ZigBee wireless sensor
network in China. A work for forest fire detection is proposed in [19]. A. Rehman proposed a
work for WSN [20]. South Koreans [21] also designed a system for fire detection in their mountains.
They named their system FFSS (Forest fire Surveillance system). They developed their system by using
WSN, middleware, and web applications. Network nodes (i.e., temperature sensors and humidity
sensors) collect measurements and send them to the sink node. Afterwards, the sink node transmits
that data to the cloud via a transceiver (gateway). Later, by using a formula, the fire risk level is
determined in the middleware program. After detecting the fire, FFSS is activated automatically.
TinyOS is used as an operating system for network nodes.
Similarly, few other systems utilize the WSN for early fire detection. Few of them use IP-based
cameras and mixed multi-sensors [22] on wireless mesh network to detect a fire efficiently. They use
these three parameters to make an efficient system to identify and verify fire. A software application
exists, which selects the closest IP base camera. When sensors sense a fire, they send the information to
the central server where the software program selects the nearest camera. That camera takes pictures
of the location and send them back to the main sink. Alarm decision is made on the basis of the
sensor’s information and selected images. Also, a clustering-based forest fire detection system was
proposed in [23]. The proposed method uses advanced communication protocols. The proposed
work consists of four major parts: (i) an approach for sensor deployment, (ii) the use of WSN for fire
detection, (iii) intra-clustering protocols, and (iv) an inter-clustering communication protocol. Aother
work was proposed by Wenning, Pesch, Giel, and Gorg [24] for disaster detection, including the fire
event. This method can quickly adapt the routing work state on the basis of the threat of possible
failure. In [25], researchers proposed a protocol for the adaptation of the Context-Aware Routing
Protocol (CAR) to WSN and named it SCAR. Energy, colocation with sink, and their connectivity was
evaluated in SCAR. For the delivery of data packets to the sink, delivery probability and forecasted
values were combined on the basis of previous knowledge of SCAR parameters. In this system, buffer
space and delivery probability are exchanged periodically with neighbor nodes. An order list of
neighbors is sorted by delivery probability, which is kept by each node. Garcia et al. [26] proposed
a work to create a model for fire detection. They performed a simulation by analyzing sensors data
and geographic information. To differentiate from the existing work, they used topography of the
environment under study.
Energy and time factors are an unavoidable requirement that should be satisfied efficiently.
The energy factor plays a vital role to maximize the lifespan of sensors in the WSN environment.
The ever-increasing demand by the market leads the researcher to invent new hardware and algorithms
that are more reliable and efficient. IEEE 802.15.4/ZigBee with cluster-tree topology [27] assures
reliable performance and efficient energy consumption that significantly increases the lifespan of WSN.
This IEEE standard reduces the time slot collision named guaranteed time slot (GTSs). GTSs can
also be used in real-time transmission scenarios. Allocating GTSs to the sensor nodes indicates
that nodes will remain in sleep mode until they get a time slot. Other anomalies, such as optimal
sensor placement, data communication, security, and sensor’s energy factors, are also involved in
sensor environments. A considerable amount of work has been done in this domain. Gul et al. [28]
proposed a work that optimized the sensor node placement and analyzed the energy constraints on a
significant amount of data passing through the WSN while the network was suffering from a DDoS
attack. Techniques like the Constrained node-weighted Steiner tree-based algorithm [29] have proven
to be helpful while creating WSN. This technique optimized the sensor node placement efficiently.
A proposed method [30] maximized the lifetime of a sensor by optimizing data aggregation. Intelligent

systems, from vehicular networks to the smart buddy and other evolutionary systems, are applied in
various fields of technology [31–35] which also poses many challenges in implementation, especially
in analyzing fire simulations without human intervention.
3. Home Fire Data Analysis
To understand the importance of the study, we did some analysis by using different fire datasets.
We took these datasets from very reliable sources [36,37]. The datasets include fire statistics containing:
(i) a percentage of homes that have fire alarms in England & Wales, (ii) causes of the fires, (iii) fire
alarms with respect to sensors type, and (iv) death data per million population because of dwelling
fires. While analyzing the house fire data initially, we examined the trend of using alarm during the
years from 1988 to 2015. Figure 1 shows the graph of this trend. It shows that almost 93.4% of houses
in English countries are now using fire alarms.
As this analysis shows, almost 93% of houses are equipped with fire alarms but the study
indicates that there are still many deaths despite the fire detection systems. Figure 2 shows the
pictorial representation of the analysis of the death dataset taken from [37]. The graph shows the
number of deaths per million people in each year. The study shows that more than ten deaths per
million population are still occurring every year. The loss of lives or property caused by fire is due to
many reasons, such as alarm failure, false alarm, no response, and many other unspecified reasons.
We performed another analysis of fire-caused losses where fire detection systems were installed.
This analysis was made on the data taken from England between 2010 and 2016. Figure 3 shows the
study of fire-caused losses per year. We analyzed fire losses due to three causes: (1) Fire damages due
to a false alarm, (2) Fire losses due to no person response, (3) Other/unspecified reasons. The analysis
shows that most of the losses were caused by false alarms. As we described earlier, most of the fires
are not detected because of sensors’ failure and thus progress. Most of the houses examined were
equipped with WSN-based fire alarm systems.
Most of the time, alarm failures are due to the breakdown of the WSN. In the WSN, the association
between sensors is essential. Therefore, the communication between sensors cannot be performed if
the network is disconnected. So, the failure of a single sensor may result in many harsh events. Most of
the sensors are battery-powered and might not have the possibility to recharge. Most of the energy is
spent in communication, and, if the sensor energy is exhausted during communication, sensor failure
occurs, and this can sometimes lead to network failure. We performed analyses on alarm’s failure
in the presence of a fire detector sensor. The analysis results are shown in Figure 4. The analysis
graph displays the percentage of true alarm generation and sensors failure with respect to the different
categories of sensors from 2010 to 2016.

4. IoT-Based Intelligent Modeling of Smart Home Environment for Fire Prevention and Safety
In this section, we breakdown of our work into four parts. The first unit describes the sensor
which collects the information from the environment and transmits it to the second unit, i.e., the
processing unit, by using the ZigBee protocol. The third unit is the GSM communication unit, which
alerts the users about the event. The fourth unit triggers the alarm. Details of these units are as follows.

4.1. Overview
The existing systems have flaws because they contain single unifunctional sensors for each target
portion in the residential place. However, if an event occurred in a particular place and the sensor of
that region was not working, then it would be highly improbable to detect the incident at its initial stage.
The second major problem is the generation of false alarms. The proposed smart home fire detection
system consists of four major parts: (i) sensor; (ii) processing unit as the main home sink; (iii) GSM
communication system; (iv) alarm system. In the sensor unit, we deployed multi-sensors, i.e., smoke,
gas, and heat sensors for each portion of the smart homes. All these sensors have their own event
detection mechanism. Figure 5 shows the complete model of our proposed work. The processing unit
contains a home sink, which communicates with the sensors through the ZigBee Protocol. The decision
of fire detection is taken on the sink on the basis of the information received from the sensors and of the
user’s response. If a single sensor node sends fire alert to the sink, it automatically activates the GSM
communication and sends an alert message to the user. The sink make decisions on the basis of the
user’s response or of the alert notification from the other sensors. After getting confirmation of a fire
event either from two or more sensors or from the user, the sink generates an alarm. Simultaneously,
the system shares the event information with the cloud and with the local server which helps to
spread the information to the basic service units. The local server is connected with the surrounding
inhabitants to inform the other houses about the current situation. We present the detail design of each
unit in the following subsections.

home fire detection system consists of four major parts: (i) sensor, (ii) processing unit as the main
home sink, (iii) GSM communication system, (iv) alarm system. In the sensor unit, we deployed
multi-sensors, i.e., smoke, gas, and heat sensors for each portion of the smart homes. All these
sensors have their own event detection mechanism. Figure 5 shows the complete model of our
proposed work. The processing unit contains a home sink, which communicates with the sensors
through the ZigBee Protocol. The decision of fire detection is taken on the sink on the basis of the
information received from the sensors and of the user’s response. If a single sensor node sends fire
alert to the sink, it automatically activates the GSM communication and sends an alert message to
the user. The sink make decisions on the basis of the user’s response or of the alert notification from
the other sensors. After getting confirmation of a fire event either from two or more sensors or from
the user, the sink generates an alarm. Simultaneously, the system shares the event information with
the cloud and with the local server which helps to spread the information to the basic service units.
The local server is connected with the surrounding inhabitants to inform the other houses about the
current situation. We present the detail design of each unit in the following subsections.

4.2. Sensors
The products derived from the fire are heat, smoke, gas, or infrared/ultraviolet radiations.
The sensors can detect one or more of these phenomena. In our model, we used smoke, gas
and heat sensors to detect changes in the above-mentioned aspects. The temperature sensors are
mainly designed to detect changes in temperature. Temperature sensors are classified into two
classes according to their operations, i.e., (i) rising rate of heat (ii) fixed temperature. The LM35
7. J. Sens. Actuator Netw. 2018, 7, 11 7 of 16
(Texas instrument, China) is a temperature sensor which is very efficient and highly calibrated. This
sensor is used to detect the rise in temperature. It may have attributes such as less heating and low
linear impedance. It can operate in the voltage range from 4 V to 30 V which is lower than 60 µA of
drain current [38]. The smoke sensors are devices that can detect smoke from a fire. The smoke sensors
are packed in a plastic cage varying in size and shape, but mostly disk-shaped, 25 mm thick, and
150 mm in diameter. MQ9 (Henan Hanwei Electronics Co., Ltd., Zhengzhou, China) is a smoke sensor
made of microaluminum oxide which is used to detect smoke in a room. In order to detect the smoke,
this sensor combines the high sensitiveness of carbon monoxide and a layer of in oxide. It contains
very sensitive components, work conditions, and measuring electrodes [39]. During a burning fire,
the gases produced (e.g., carbon dioxide, carbon monoxide, and many others) are very hazardous.
The devices which are used to detect gases like CO, CO2, etc. are called gas detectors. These devices
are used to identify toxic, combustible, flaming gases, and also depletion of oxygen. These devices
can be grouped into different classes (infrared, photoionization, catalytic, semiconductors, oxidation,
etc.). They are available in two primary forms: (i) portable devices (ii) fixed gas detectors. MH-Z19
NDIR (Zhengzhou Winsen Electronics Technology Co., Ltd., Zhengzhou, China) is an infrared gas
detector which is quite common. These sensors are tiny, have a long life, and work on the principle of
non-dispersive infrared (NDIR) to detect the presence of carbon-dioxide in the air very efficiently.
In proposed work, we used these three sensors for each sub-portion and set a threshold for these
sensors. For the kitchen environment, we used different limits. The sensors sense the environment
and collect data in raw form. If the sensed data is higher than a threshold, which is δS, then the sensor
reports the information as fire. This report goes to the sink which works as a processing unit that
analyzes the report.
4.3. ZigBee as the Used Communication Protocol
To set up the wireless sensor network, it is possible to use different topologies, depending on the
number of sensor nodes and communication methods. The four most common topologies are: (i) The
peer to peer, (ii) The mesh, (iii) The tree, and (iv) The star network topologies [40]. Comparatively,
the star network topology setup is very competent compared to other network topologies. Figure 6b
shows the star network topology. For communication between the sensor and the home sink, we
used the Zigbee protocol. Figure 6a shows the communication method. ZigBee is based on IEEE
802.15.4 standard specification and uses high-level communication protocols to build personal local
area networks. It uses tiny, low powered, digital radio devices and it can be used to transfer data over
some limited distance from 10 to 100 m. This distance depends on the environmental conditions, and it
varies for different homes. It is considered a low-powered protocol because it needs a minimal amount
of energy to receive and transmit data.J. Sens. Actuator Netw. 2018, 7, x FOR PEER REVIEW 8 of 16

It consumes most of its energy in transmitting the data. This protocol uses different types of
devices like: (i) Coordinator, (ii) Router, and (iii) End devices. ZigBee uses as a coding technique the
direct sequence spread spectrum, abbreviated as DSSS. Therefore, it uses two primary types of
communication modes, i.e., (i) Beacon-enabled and (ii) Non-beacon enabled. The outlines of the
beacon-enabled and non-beacon-enabled communication are shown in Figure 7a,b [41]. In
beacon-enabled communication, the beacon frames or beacon packets are broadcast periodically by
the PAN coordinator [41]. In non-beacon-enabled communication, the PAN coordinator broadcast
the beacon packets randomly. When the sensors are in the inactive state or do not send the data, this

the beacon packets randomly. When the sensors are in the inactive state or do not send the data, this
protocol automatically turns off its interface to save energy. When it sends beacon messages, the nodes
remain in the active mode. Usually, beacon intervals are between 15.36 ms and 251.65 ms at the speed
of 250 kb/s, but this depends on the data flow rate. By keeping in mind this ZigBee communication
model, we used ZigBee for data communication.

4.4. Processing Unit
The information collected from the sensors is then sent to central processing hub or main home
sink wirelessly. Nowadays raspberry pi, abbreviated as (RPI), is being used as the primary
processing unit. The main reasons for choosing it are its popularity and versatile functionalities. This
device works as a processing unit and processes the data that comes from sensors to decide whether
to activate the alarm. To handle the information which comes from the sensor nodes, RPI starts
initializing the modules that are required for that specific processing. For example, in our proposed
method, we used SMS alert system via GSM technology and then GPIO general purpose input–
output. If the measurements that come from the sensor nodes consist of a fire alert, the GSM module
is activated and send an alert SMS automatically to the specific user. The general purpose of the
input–output GPIO module is to check the user response to the fire. This response will always be in
the form of “yes” or “no”.

If the response is “yes”, this means a fire is present, but if the response is “no”, that means no fire.
For each of the deployed sensors in homes, the GSM module gets activated automatically. The final
decision of alarm depends on both the user’s response and the sensor’s readings. The flow diagram of
this system is shown in Figure 8. If a single sensor’s reading contains a fire alert message, then the
system does not make any decision on behalf of this single reading. The system waits for the response
to a pre-warning SMS. After receiving a response to the pre-warning SMS, that can be either “yes” or
“no”, the alarm will be activated if the response is “yes” or if the system receives the event notification
from two or more sensors.

5. Simulation
To evaluate the efficiency and effectiveness of our proposed work, we simulated fire in a smart
home using the Fire Dynamic Simulator, abbreviated as FDS [42]. FDS is a tool developed by
NIST to simulate a fire in different environments. It is a computer language program which solves
Navier–Stokes Equations numerically. It is written in FORTRAN and it takes multiple inputs like:
(i) Sensors thresholds; (ii) Initial values of sensors; (iii) Humidity; (iv) Different parameters to design
the environment, and many more. By using these inputs, it computes the Navier–Stokes Equations.
Figure 9 shows our simulated work scenario using FDS. We divided the house into four parts,
i.e., (i) Bedroom; (ii) Living room; (iii) Kitchen; (iv) TV Lounge. To monitor fire, we examined three
different parameters, i.e., temperature, gas, and smoke. For each portion of the house, we used three
sensors, while 12 thermocouples were used in whole. The initial inputs of the sensors were 25 ◦C,
15 ppm, and 60 ppm for temperature, gas, and smoke sensors, respectively. We ignited the fire in the
kitchen and we assumed that it started 30 min after the beginning of the simulation. After the fire
started, it spread at a rate of 1500 KW/m2.
We performed the simulation for both scenarios, first in the presence of a single unifunctional
sensor and then in the presence of the multi-sensor. For the first scenario, we used temperature sensors
to monitor the fire. As the fire started from the kitchen, we made this sensor inactive and continued
11. J. Sens. Actuator Netw. 2018, 7, 11 11 of 16
the simulation for 40 min. For the second scenario, we performed the same simulation and setup, as
shown in Figure 9. We measured the data generated by the simulation for these two scenarios.

Figure 9. Indoor scenario of the simulation using FDS.
To check the efficiency of our work, we also implemented our proposed method by using C++
programming language. We performed our implementation in visual studio 2017 in which we used
C++ libraries. We installed our simulation environment and visual language on a machine with
specification “Intel(R) Core(TM) i5-3570 CPU @ 3.40 GHz 3.80 GHz and RAM 16 GB”. The data
produced by FDS during fire simulation was used for our algorithm to check the efficiency of our
work.
6. Results
While performing the simulation, the system took the initial values of the sensors and the other
parameters. We set a threshold for every sensor and used the GSM module to avoid false alarms.
The system generates the alarm when two or more sensors value exceed the sensors’ threshold
values or if the user response contains a fire confirmation message. The system was tested many
times and produced almost zero percent of false alarms. We compared the simulation results with
those from other existing techniques to check the efficiency of our proposed method and we found
that our system is efficient. We discuss our simulated results in the following subsections.
6.1. Sensor Behavior
We simulated two different scenarios to compare the sensor’s behavior and overcome the
problem discussed in this paper. First, we simulated a single-sensor scenario by deploying a
temperature sensor for each portion. Then, we used a multi-sensor as in our proposed work. After
performing both simulations, two types of data were generated, i.e., (i) data generated during the
single-sensor environment simulation, (ii) data generated in the multi-sensor environment
simulation. Then, we examined the sensor’s behavior for these datasets, as shown in Figures 10 and
11, respectively. For the first scenario (uni-sensor), we assumed that the fire started from the kitchen,
we made kitchen sensor in-active and then checked the behavior of the other sensors. Figure 10
shows the sensors’ behavior in the unifunctional, single sensor simulation. WE found that the
kitchen sensor was in-ctive throughout the fire. When the fire and heat spread out, the other sensors
deployed in TV lounge, living room, and bedroom started detecting a temperature increase after 8,
14, and 18 min respectively.
When we simulated and analyzed our multi-sensor system, we found that it detected the event
in quite a short time as compared to the single sensor. As the fire started from the kitchen, we
analyzed the sensor’s behavior only in the kitchen.

the sensor’s behavior only in the kitchen.
The graph in Figure 11 shows that, when the fire started, the sensor that we deployed in the
kitchen started sensing the environment immediately. When the temperature, gas, and smoke values
exceed the threshold values, the sensor started sending fire alerts to the sink. The simulation results

proposed approach and compared it with the 50% and 100% duty cycle, and the results are shown
in Figure 12. Duty cycles of 100% and 50% indicate the time when the radio interface remains in the
active state. An energy-efficient communication stack has a duty cycle less than 1%. The sensors used
in each room had a pair of AA batteries (3000 mAh). The total energy consumption of the sensors
during 12 h was calculated (for both 50% and 100% duty cycles), and the results are presented in

Figure 13 shows the results for energy consumption. The sensors used in some rooms consumed high
energy compared with the sensors in others rooms. More energy was consumed during the morning,

of the sensors during the fire event. Figure 14 shows the energy consumption during one hour of
fire. It shows that more energy was consumed during the fire.

7. Conclusions
The primary objective of the proposed work was to design an intelligent analysis of smart
home for fire prevention. Two major flaws of the currently used systems are: (a) the fire prevention
systems mostly use a single sensor for event detection but problems arise if the target sensor does
not detect the event; (b) false alarms can be generated. Overall our proposed method provides a
solution to these problems. We introduced an efficient technique to overcome these problems. We
used multi-sensors for each region in smart homes. To reduce the false alarms, we used the GSM
communication system. The purpose of GSM communication was to alert the user at the very initial
time of the fire. Fire detection decisions were made by the main home sink connected with all the
sensors wirelessly. The decision was made on the basis of the sensor’s values or the user’s response.
We simulated fire in FDS that was designed by NIST, and the generated results of the simulation
were analyzed by our proposed algorithm that we implemented in Visual Studio using C++ libraries
programming language. The simulators were installed on a machine with the following specification:
Intel(R) Core(TM) i5-3570 CPU @ 3.40 GHz 3.80 GHz, and RAM 16 GB. The energy consumption
of the deployed sensors was also computed, and we noticed that it was within an acceptable limit.
The results and other evaluations showed that our proposed work fulfills all the desired requirements.
In the future, as we used multi-sensors for the detection of fire and the amount of data generated by
the sensors during a fire was high, we will work to find a method that deals with this high amount of
data efficiently.
