Abstract Multimedia content boosts the learning trends. This paper is aimed to presents
an electronic learning system based on Internet of Things (IoT) for the synchronous and
asynchronous communications. The infrastructure of IoT provides the adaptable, scalable
and open access for the eLearning paradigm. The multimedia-based IoT-centric environ-
ment is suitable to enhance the effectiveness of the delivery of learning contents.
Students can take full advantage of 7As of IoT, which provides the opportunity to the
students that they can access everything on the internet at any time and place. It creates a
flexible eLearning paradigm for the teachers and students. The proposed eLearning
modeluses sensors to detect the student location, temperature, and mobile camera to
identify the student activeness in thelearning environment. Virtual campuses are con-
trolled from a centralized location that may be called the head office. The MAQAS
framework provides the solutions to the problems and analyzes the results for the
efficient and connected eLearning paradigm. The MAQAS system is used to answer
student’s queries, which are responded to automatically by agent-based question answer-
ing system. The results show that the students’ participation towards learning and
teacher’s pedagogy are more efficient in synchronous and asynchronous modes. Perfor-
mance evaluated by comparison to the existing question answering Live QA Trak, Quora

1 Introduction
Electronic Learning (eLearning) is utilized to teach individuals nowadays. Various schools are
beginning distinctive courses by utilizing eLearning for secondary education level to degree
level and even at postgraduate level. This paper depicts the best-known distinctive machine
studying methods to help up the e-Learning training standard and model [2, 12]. Exhaustively
supervised and unsupervised systems are portrayed here for the e-Learning standard to the auto
answer of learners’ inquiries. Web bot is consolidated for the studying of people who are
taking courses in remote mode [15]. This paper focuses the multimedia-based IoT system
architectures and services used in eLearning paradigm. IoT is well defined, and it offers the
innovative techniques for the connectivity of devices with systems. The computing devices are
connected to existing infrastructure using IoT. IoT provides the variety of connection that can
be used for the Machine-To-Machine (M2M) communications. It also offers the connectivity
for the devices, system, and services by using different protocols. The smart object like smart
mobile phone, watches, and other personal handheld devices, as well as embedded devices, are
utilized for the automation of the all the fields of the life [10]. The IoT with multimedia offers
services multimedia data optimization, camera networks, complexity aware algorithms de-
signs, security algorithms, low power design, distributed network implementation and man-
agement, and for audio-video services [4, 8].
The mix of eLearning with IoT offers the utility computing as Software as a Services (SaaS).
The deployment of the eLearning resources and tools are accessible by using the connectivity
through IoT. IoT provides the services at less hardware requirement need and connects offers at
minimal cost. That leads to lessening the burden of the infrastructure cost. It allows the institution
to focus on their core business of teaching instead of concentrating on the search and purchase of
cost-effective module for the eLearning System [17]. It also helps them to obtain the latest
technology and updates without charges. IoT provides the following advantage in eLearning [8]:
& IoT delivers the better facilities for the students to get connected with their Institute and
teacher 24/7, even they are travelling from one place to another place
& A student may take the online exam by any of the internet connection through Wi-Fi,
GSM-based 2G, 3G, 4G and 5G.
& The IoT offers the connectivity to anyone, anytime and anywhere. The eLearning appli-
cation development and accessibility are demanding high web development skill.
& As student are connected through IoT, they have used to take back on OneDrive, Google
Drive, and another lot of space available by the other vendors.
& It also allows the students to work and take lectures from anyplace, i.e. library, home,
office, campus, workplaces.
& Student using the IoT having access to their files and data on the laptop, mobile and
desktop PC to use an update.
& Using IoT and internet-storage crash-recovery techniques are nearly unneeded.
IoT-based connection scenarios are too many that used to connect the devices for a short
time as well as permanent [1]. The connection modes used for the IoT device connectivity are

following: Wired technology, Wi-Fi technology, mobile GMS based connectivity, ZigBee,
Bluetooth, ISA100, 6LowPAN and Hi-Fi [27, 30, 38]. IoT connected scenario is shown in
Fig. 1.The student can connect the servers, printers, scanners, laptop, vehicles, tablet,
smartphones, healthcare units, IP phones, gadgets and sensors by the IoT-centric devices for
the collection of multimedia data. The eLearning needs connectivity with the learning man-
agement system and teacher on the priority basis for the student.
1.1 Contribution

Agent-based Question Answering System (MAQAS). The MAQAS framework facilitates the
student and teacher interaction in an improved fashion. Multimedia base Internet of Things
provides the connectivity to the students and teachers with significant improvements. The
mechanism introduced in this study enhance the learning skill of the student. The student using
the IoT having location free access to their files and data on the laptop, mobile and desktop PC
to use an update. Moreover, the sensors used for the collection of data for the identification of
location, study and lecture area conditions and Mobi-came for the attentiveness of the students.
The manuscript is organized as follows: Section 2 is literature review which provides the
comparative and existing material about the multimedia, eLearning, and IoT. Section 3 is the
comprises of the proposed solution. In this section multimedia agent based question answering
system is discussed. The 4th Section gives the results and discusses the proposed solution and
comparisons with other question answering systems. References in 5th section proceed the

2 Literature review
The information values are increasing at high speed with a contribution in the interconnection
provided by the IoT for the information processing and transformations. IoT plays an excellent

role for the betterment of the society and humanity. IoT replaces the existing connectivity with
new trends and techniques. Now connectivity for the peoples becomes a service. People may
connect in seven A’s fashion. The IoT provides the connectivity for Anywhere, Anytime,
Anyplace, with Anyone, Anything using Any-network path for any service, which the students
are required. This well defined in the ITU vision which describes the four A’s, i.e. anyplace,
anytime, for anyone, and connectivity for anything [3, 22] as shown in Fig. 2.
2.1 Asynchronous communication
In eLearning paradigm, synchronous and asynchronous types of communication tools are used
by the student-teacher interactions [19]. Synchronous communication tools are used for the
group chat, one-to-one using Skype, TeamViewer, and so on. The devices utilized for the
synchronous communication have the fast data transfer rates. In asynchronous techniques, the
student and teacher are present in virtual space for communication. Asynchronous does not
need to send and receive the data in real time. It is slower than synchronous communications,
i.e. electronic mail, Moderated Discussion Boards. Student by using the asynchronous tools
repeat the lectures as many times as they required. The asynchronous tools provide the
facilities to students to participate in group studies. It enhances the learning of the student
by the group activities. The use of the asynchronous tools eliminates the preconceived notions
about the race, sex, and colour. These tools are time efficient and profitable.
2.2 The role of IoT in eLearning
Virtual campuses are controlled from a centralized location that may be called the head office.
The LMS may contain the portal software for course management [20]. LMS will have
additional tractability in the plan and incorporation of intelligent agents. The agent is a piece
of code with persistent ownership and control of working mechanism. In-house designed and
development of agents can be more skilful, more accessible and faster. However, this is only
feasible for more prominent institutes with better programming and database expertise, as well
as substantial resources [7, 19]. These institutions may have IT support units and cloud

services or more research groups within their academic departments [13, 21, 28].FUNF-
Journal allows the user or researcher to configure data collection parameters for over 30
different built-in data probes, including all phone sensors, as well as additional data types and
high-level probes that generate inferences and new data based on the output of sensor data.
Further probes are continuously added to the system. The app supports importing and
exporting of probing configurations, as well as remote configuration (with user permission).
The FUNF tool is based on the simple configurations that data for investigation is
automatically gathered if the smart mobile phone used in daily routine life. This data is stored
securely on the smart cell phone in an encrypted format. This information used to be extracted
from the smart cell phone in many ways. Data collected by manually exporting is done via
email or any other Android service. Data can be transferred by manually copying to another
device by the memory card. Data also be collected by linking DropBox account with
application configuring FUNF to auto uploading using IoT services. When the server config-
uration is set up, the data collection configuration could also be performed remotely. Once the
data is extracted from the phone, we provide a set of desktop utilities that allow decryption of
the data, demonstrate some examples of visualizing and considering the collected data.
2.2.1 Student-teacher interaction systems
The automated question answering (QA) track, which has been one of the most popular tracks in
TREC for many years, focuses on the task of providing automatic answers to human questions.
The Question Answering track primarily deals with factual questions. The responses of the
participants are extracted from the News article corpus. While the task evolves to model increas-
ingly practical information needs, addressing question series, list questions, and even interactive
feedback, a significant limitation remains: the questions do not directly come from real users in real
time. The LiveQA track revives and expands the QA track, focusing on Blive^ question answering
real-user questions this year [9]. Real user questions, extracted from the stream of most recent
questions submitted on the Yahoo Answers (YA) site that has not yet been answered by humans,
will be sent to our systems. Then our system provides an answer in real time [9].
Quora is a fast-growing social Q&A site where users create and answer questions, and
identify the best answers by up-votes and down-votes with crowd wisdom. The Web of Data
has grown to contain billions of facts about a broad variety of domains. While experts can
easily access this wealth of data, it remains difficult to use for non-experts [25]. The pre-
implemented HAWK system, however, performs better on hybrid questions than on plain
English questions. Systems like YODA, which do only provide answers without a SPARQL
query cannot be analyzed sufficiently [32]. AskMSR to a new question answering dataset
created using historical TREC-QA questions; we find that the critical step, query pattern
generation is no longer required but instead, more in-depth NLP analysis on questions and
snippets remains critical [31].
3 Proposed Multimedia and Agents based Question Answering System
(MAQAS)
The Multimedia and Agents based Question Answering System (MAQAS) in eLearning paradigm
help the student to find answering more relevant and accurate. The proposed solution is based on
multimedia data for the eLearning systems [18]. This solution is agent-based to facilitate the student

and utilization of the resources efficiently. Text Mining comprises of the pattern discovery from the
contextual documents. Mobile Sensor for Student data collection using FUNF is shown in Fig. 3.
The Multimedia-centric Internet of Things (mm-IoT) is the collection of interfaces, proto-
cols and associated multimedia-related information representations that enable advanced
services and applications based on human-to-device and device-to-device interaction in
physical and virtual environments. Information refers to data sensed and processed by a
device, and communicated to a human or another device [26]. The IoT-based for a smart
framework for the eLearning is used to student-student interaction as well as for the student
teacher interaction [16]. Student-teacher collaboration in IoT scenario is shown in Fig. 4.
The smart mobile phones are now integrated with biometric sensors which used with Closed-
Circuit Television (CCTV) camera to a highly sensitive location in the city [23, 34]. Sensors are
used to make the reality, and now sensors are shifting from smart to intelligent manner [11].
Biometric is also used for the for the identification of the individuals same as computerized national
identity card [35]. Billions of the sensors are deployed and connected through the smart mobile
phones with IoT, and much more are connected through networks protocols with these smart
mobile phones. The data is collected from the sensors are an interoperable format for creating and
developing systems that break the soil vertically and harvest in cross-domain that is useful for the
application connects to IoT. In eLearning paradigm, the IoT applications are used no most widely.
Multimedia-based Student’s Interaction with Intelligent [11, 37] LMS is shown in Fig. 5.
3.1 Student connectivity technologies
In eLearning paradigm, students have some connectivity methods used to connect with LMS
and teacher. The most widely used method is campus-based student uses the Wi-Fi internet
services available on campus. The other methods are used for the connectivity of the IoT
devices possessed by the students as shown in Fig. 6.
The mobile internet, which is mostly used by the countryside student where internet line is
not available. The mobile phone internet connection technologies are categorized into four
types: 2G, 3G, 4G and 5G as shown in Table 1. The mobile internet services are provided by
the different companies PTCL, Mobilink, Warid, Ufone, Zong, and Telenor [14, 24].

The coverage of the companies is dependent upon directly at PTCL services. PTCL
provides the backbone infrastructure for the telecommunications services. These internet
service provider companies located Karachi to Skardu in Pakistan. Students use these services
to connect LMS in eLearning paradigm. Teacher commonly used the corporate internet service
provided by the Higher Education Commission at offices. The teacher uses the higher
bandwidth as interacted with some students for their problem-solving.
3.2 Data collection from IoT-based distributed sensors
Data collection from IoT-based distributed sensors is done with the help of following modules.
& Mob-Cam for Student Attentiveness
Mobile camera is used to measure the student attentiveness by the student face recognition.

& Temperature Data
The temperature of the location is detected by using the mobile sensors for the analytical
purposes. This dataset is used for the further recognition of the conditions in which student are
listening video lectures [6].
& Location Data
The student coordinates are collected through smartphone GPS sensor as shown in Table 2.
These coordinates are helpful to detecting the location of the student. Once the student location
is identified then decides for either immediate appointment is possible in case teacher has a
free slot. Otherwise, appointment deferred to some appropriate time as shown in Table 2.
Appropriate time will have sought out by a collaboration of the student. While also
communicate to the teacher for the available free slot so, that student teacher synchronous
interaction is possible for a better solution of the student problem. Now Google Map is used to
find out the locations of students. User smartphones are used to collect their Global Positioning
System (GPS) coordinates. Google Maps API has used the location into coordinates like
latitude and longitude dynamically, and these coordinates are used to place markers on the map
as shown in Fig. 7. Multiple markers show locations of students, whether they are on the
campus or somewhere else while using the framework which is based on multimedia in
eLearning as shown in Fig. 7.
Now agent A2 collects the feedback from the student. This feedback along with question
relevancy used to measure the need for multimedia-based communications. If the student

feedback is satisfactory, then the agent A2 will fix major role-plays in the next step towards
appointment. In asynchronous mode, students have, limited facility to post their queries
through LMS based interface.
These queries are commonly text-based, and no multimedia facility is available. In
MAQAS proposed model, student’s queries are answered automatically by agent-based
question answering system. The teacher answers selected queries locked by the system.
Teacher reply is also containing the excessive text with graphics are optional. Therefore,
there is a strict need to introduce a framework for the student-teacher interaction that
provides the multimedia-based communication to satisfy the student queries. IoT module
classification regarding power management, energy storage [29], radio frequency, sens-
ing modules is shown in Fig. 6.That is based on instructor feedback, which is being
validated by the MAQAS and suitable for both distances learning and the asynchronous
online environment by merging this solution into existing management scenario. This
scenario prevents students from unnecessary tension in getting their reply in a scenario in
which teacher is not physically present [5, 33]. To shorten incredible flow of research in

the field of signals, audio, video, sensors and imaging informatics is ongoing. It may
result in the determination process for this area Bsignals, audio, video, sensors and
imaging informatics" which carried out brilliant articles, speaking to research in four
separate countries. The fields of cerebrum machine interfaces, sound observation in
telemonitoring, delicate tissue exposing, and body sensors have been chosen. The
segment can just mirror a little parcel of the overall productive work in the field of
signals, audio, video, sensors and picture transforming with applications in stimulating
informatics.
4 Results and discussion
Let’s run a simple query Bwhat is the role of the operating system?^ on MAQAS system and
take a subset of the keywords and calculate the relevance for the decision-making at a later
stage to fix appointments of the student-teacher interaction in synchronous communications.
Table 2 denoted the keywords relevancy on small subset keywords of the answer delivered to
the student that is calculated. Now agent A2 collects the feedback from the student. This
feedback along with question relevancy used to measure the need for multimedia-based
communications. If the student feedback is satisfactory, then the agent A2 will fix major
role-plays in the next step towards appointment. Agent A2 collects the coordinates through
smartphone GPS sensor as shown in Table 2. These coordinates are helpful to detecting the
location of the student. Once the student location is identified, then agent A2decides for either
immediate appointment is possible in case teacher has a free slot. Otherwise, appointment
deferred to some appropriate time.

5 Conclusion
The outcomes of this research are the design of the intelligent framework with the help of
advanced tools and technologies, which are used more efficiently to facilitate the student.
Question answering in the eLearning paradigm plays a crucial role to enhance the student
learning. Student learning process in affected severely if the answering is delayed. The
eLearning solution can be developed with the current technologies that lead to the multi-
media data. The analytics presents the learning behaviour, outcomes, and the learning
targets. The analysis is significant by the study of the relationship between multimedia data
used for the academic and student-teacher interactions for educational performance eval-
uation and enhancements. This framework supports the main eLearning components for the
convenience, easiness, accessibility, connectivity, and flexibility. eLearning system is
mostly facing challenges of optimizing resource that can be handled by the multimedia
and IoT-centric devices. Multimedia contents are fully utilized for the enhancement of the
learning curve of the students using IoT based infrastructure. eLearning with multimedia
settled the goodness of an IoT-based solution. The advantages focusing the integration of an
eLearning system into the IoT-based system can be highlighted as good flexibility and
scalability for the resources, including storage, computational with internet connectivity.
However, these are just initial steps towards an open line for research and exploitation of
eLearning and IoT-based computing platforms. In future, the proposed model will be used
in healthcare, engineering with more internet-connected devices. The increase in the
number and types of the device open the new horizon for the students and learners.
