The value conduct of cryptographic forms of money remains to a great extent neglected, giving new chances to scientists and business analysts to feature the likenesses and contrasts with standard monetary costs. Hence the paper is focused on this area. he results are compared with various benchmarks. Predictions are done using statistical techniques and machine learning algorithms. A simple linear regression (SLR) model that uses only a single-variable sequence of closing prices for forecasting, and a multiple linear regression (MLR) model that uses a multivariate sequence of prices and quantities at the same time. The simple linear regression (SLR) model for univariate serial forecasting uses only closing prices. Mean Absolute Percentage Error (MAPE) and relative Root Mean Square Error (relative RMSE) performance measures are considered. The accuracy achieved by the ARIMA model on our dataset is the highest, followed by Multivariable Linear Regression and LSTM.

Several types of IoT are available in the recent years based on their features and applications. Narrowband IoT (NBIoT) is one of the 3GPP standardized solutions for massive machine type communications (mMTC). It is designed for the large scale mMTC to provide coverage over a large area. Therefore, NBIoT is one of the most attractive low power wide area (LPWA) technologies. It is preferred for the large scale deployments in the large projects such as smart farming, healthcare, smart cities and smart grids. However, it is also suitable for low power domestic applications such as smart home and pets’ tracking. The LPWA features of NBIoT make it the primary choice for several emerging applications such as healthcare, agriculture, utility management, tracking of objects, smart city monitoring, retail management, smart grid monitoring, and industry applications. In this article we provide the principles and applications of NBIoT for the large scale deployments.

In this work, we optimize the MobileFaceNet face recognition network MobileFaceNet so as to deploy it in embedding environment. Firstly, we reduce the model parameters by reducing the number of layers in MobileFaceNet. Then, the h-ReLU6 activation function is used to replace PReLU in the original model. Finally, the effective channel attention module efficient channel attention is introduced to obtain the importance of each feature channel by learning. After the optimization, the MobileFaceNet parameters are compressed to 3.4 MB, which is smaller than the original model (4.9 MB), and the mAPs reach 98.52%, 97.54% and 91.33% on the test sets of LFW, VGGFace2 and the self-built database, respectively, and the recognition time is about 85 ms/photo. It shows that the proposed method achieves a good balance between the model complexity and model performance.

end-user or Internet of Things(IoT) devices at the edge of the network. One of the main challenges of fog computing is to
select the right fog node to deploy and run IoT application services, which is commonly referred to as the fog service
placement problem (FSPP). However most schemes model FSPP as a single objective optimization problem. These single-
objective optimization schemes usually cannot meet the needs of increasingly complex engineering practice. In this study,
we model the fog service placement problem as a constrained multi-objective optimization problem, which aims to
improve the resource utilization of the system and reduce network latency and service placement costs. Secondly, the
elitist nondominated sorting genetic algorithm II (NSGA-II) is used to optimize the constrained multi-objective service
placement problem. Experimental results show that the proposed scheme is superior to the existing schemes in terms of
overall performance.

in the form of packets i.e Software defined Networking (SDN). It is often recognized as the network paradigm acquired by an
isolated independent control plane by the means of the underlying networking interface. As the communication medium is
getting rapidly increased, the usage of the number of resources are also increasing in the same ratio, this results to connectivity
problem in communication networks as well. If the development in technology is gaining more interest, the resource utilization
will also increase.

OBJECTIVES: In the proposed work here, we need to establish the connection between the client (or the end user) and the
server by calculating the network performance using the parameters such as server response time and the throughput of the
network by the method of load balancing.

METHODS: This paper aims to identify the new methods or techniques to improve the performance of SDN with the increase
in reliability, specifically required to improve the real-time data delivery. Alternatively, a reliable disjoint, distributed Multi-
SDN controller will be used, to collect the updated network information like packet size, connectivity, packet flow etc. The
methods involved are ideal controller optimization technique, distruption acquiscent technique and Maximum flow shortest
route technique.

RESULTS: From the results obtained by the simulation, the Reliable Load balancing Fault Tolerant Multi-SDN
Controller(RLFTMS) approach is more reliable, fault tolerant compared to the other existing traditional mechanisms.

CONCLUSION: Load balancing based on the server response time, throughput is being compared , this improves
the server workload ditribution among various datacenters. Ultimately the customers or clients will have a great
experience in terms of the reducing response time and increase in the throughput.

These technologies are supported by wireless communication.
Currently, IEEE802.11 is a widely used wireless communication standard. This IEEE802.11 standard is expected to improve
the usability of construction machinery, similar to other mobilities, such as vehicles. However, its communication
characteristics are unknown. Here, we evaluate the performance of a wireless local area network (WLAN) comprising
wireless communication modules implemented in an excavator. In particular, we focus on the throughput when sender and
receiver positions are changed. Experimental results were used to characterise the WLAN device communication between a
PC and a communication controller. We found that the IEEE802.11 WLAN has been confirmed as having applicability to i-construction.

It offers types of assistance and applications, for example, location tracking, medical applications, and human activity examination. All android smartphones have motion sensors i.e. Accelerometer, gyroscope, in order to detect motion of a user in a very precise way. In early conditions, committed sensors were utilized for activity acknowledgment. Different techniques are developed for distinguishing normal or human activities scenes in the crowd by processing the video or an image. A novel KNN-SVM human activity detection method is proposed to detect human activities in the UCI dataset for complex multi-process physical activities. Model trained with machine learning algorithms to capture the temporal dependency, normal sequences with high dimension is uniformly utilized to train the model to discriminate each activity. In the classification process, 2 different efficient classifiers are applied to identify the types of human activities in the UCI dataset. Support Vector Machine and K-Nearest Neighbour are applied in the proposed method for the classification. The efficiency of each classifiers is about 85% to 87%. The classification efficiency is comparable with existing literature after applying the majority decision in these classification techniques.

In this context, the code requires that the wind turbine system participate in the regulation of the voltage. Any variation in voltage must be compensated by producing or absorbing reactive power. This article studies the modelling and control strategies of a wind energy conversion system based on a doubly fed induction generator. It presents a linear quadratic regulator with integrator (LQI) and an exact linearization feedback (ELF) controller for a doubly fed induction generator (DFIG). In the ELF technique, the nonlinear model of DFIG is linearized and the reference of active and reactive powers values are calculated by using reactive power management algorithm.The simulation results show that the decoupling control strategy for DFIG is satisfactory and the predefined operating conditions are respected.

However, such a task usually needs the resource consumption of mobile devices.

OBJECTIVES: the main goal of this work was the design of the context aware infrastructure for the healthcare applications embedded on mobile devices. This last aims to the integration of the context awareness into the execution environment and providing a adequate methodology of the generic context manager, with the maintenance of low level the resource consumption.

METHODS: This collected the context information (medical data) thanks to the component (Context Element Monitor). When the components set acquire values of different elements context which belong the same class, these components run in the same time. it is mean the execution of its in a group way. From the state of monitors (ACTIVE or DISABLED), our system creates the new context situation. The mobile application is structurally an assembly of services. The adaptation methodology revolves around the execution manager of services according to the new created context situation. This approach ensures the best use of resources depending on the characterization of context and reduces the amount of contextual information in the adaptation processes.

RESULTS: We evaluated a memory space in three cases, since it is the most resource that is affected in the field of the mobile health (mobile patient monitoring application). For this, we estimated the consumed memory at two levels: the first is the management module "Context Manager" and the second level considers the adaptation procedure. In the Context Manager, the first and the third case were the exploited memory space was almost identical, Knowing that its consumption is varied between 1556 and 2026 KB. But in the second case, it increased and become varying between 2424 and 6848 KB. the other hand, in the adaptation mechanism, it is necessary a huge space of a memory for managing services more than 40000 kb.

CONCLUSION: Our own approach of context manager and adaptation can open the new way in the m-health applications development. This allows these applications that can exploit the great quantity and the different type of a medical data with the best use of the memory space.

However, the Aloha protocols used for the media access are inefficient when the network size is high. As a result, a Distributed Queuing (DQ) algorithm is being proposed to replace the conventional access schemes because of its superior network performance. In this paper, we study the algorithm with no prior consideration of any underlying technology at the physical layer. We perform a steady-state analysis of the algorithm in a network where the traffic is composed of periodic and urgent packets. It was found that for high traffic from the network all the nodes were taking part in each contention. Nevertheless, for better performance in terms of access delay and packet drop rate, it was preferable to operate the algorithm in the small traffic interval. Moreover, the downlink traffic has been observed to have a significant impact on the stability of the algorithm.

Classical Group Key Management (GKM) schemes perform inefficiently in dynamic IoT environments, wherein nodes frequently leave or join a network or migrate from one group to another. In this paper, we present a highly efficient and secure GKM protocol for dynamic IoT settings, which maintains forward and backward secrecy at all times and is completely resistant to collusion attacks. Also, our protocol is highly flexible and can handle several new scenarios in which device or user dynamics may take place, e.g., allowing a device group to join or leave the network or creation or dissolution of a user group, which are not handled by schemes proposed in prior work. We evaluate the performance of the proposed protocol via extensive mathematical analysis and numerical computations.

Nonetheless, we can consider that the Internet of Things broadly refers to the trend towards generalized interconnection of all the objects that surround our daily lives, places and physical environments. Among the success keys of Iot there are protocols. However, the lack of a single connectivity protocol causes a lack of interoperability between IoT devices and applications. In this article, we present a detailed comparative study of the Short-range network protocols. Then, we will present the operating models of these protocols. There models facilitates the in-depth understanding of how network protocols work. Subsequently, from our comparative study already established and these proposed models we determine the priority of the criteria of these protocols. Using the projection of these criteria on the proposed operating models. This will help to choose the adaptable protocol for a type of IoT applications.

This is performed using inertial sensors that measure the orientation at several positions on the body. Using these measurements, this work provides a preliminary analysis of the differences between experienced and novice rowers, or between a good and a bad technique. The analysis shows that the measured postural angles show no clear trend that would set apart experienced and novice rowers or a bad and a good technique. However, there are clear differences in absolute postural angle's consistency and timing consistency of strokes between novice and experienced rowers. We also applied a machine learning technique to the data to find the similarities between different rowers and an experienced reference rower. The results can be used to compare the quality of the rowing technique with respect to a reference. In this paper, we present our initial results as well as the challenges that need to be further explored.

outbreak a pandemic, and quarantines are playing a vital role in containing its spread. But globally, the
defections of the quarantined subjects are raising serious concerns. If COVID-19 positive, the absconding
quarantine subjects can infect more people, which makes the timely detection of them vital. As the literature
suggests, a wearable makes a subject more compliant towards healthcare routines/restrictions; thus, in this
work, we have designed an IoT based wearable quarantine band (IoT-Q-Band) to detect the absconding. While
designing it, we kept in mind the cost, global supply chain disruption, and COVID-19 quarantine duration,
which the WHO recommends. This wearable prototype, with the bundled mobile app, reports and tracks the
absconding quarantine subjects in real-time. IoT-Q-Band is an economical solution that could benefit lowincome regions to prevent the spread of COVID-19.

Nodes follow a synchronized, periodic sleep-wake up schedule to maximize the lifetime of the network. The implemented network consists of 24 sensor nodes in a 3 acre maize farm and its performance is captured by 7 snooper nodes for diﬀerent data collection intervals: 10 minutes,1 hour and 3 hours. The almost static nature of wireless links in the farm motivated us to use the same tree for a long data collection period (3 days). The imbalance in energy consumption across nodes is observed to be very small and the network architecture uses easy-to-implement protocols to perform diﬀerent network activities including handling of node failures. We present the results and analysis of extensive tests conducted on our implementation, which provide signiﬁcant insights.

UV-C is employed as it has germicidal properties, in particular - bacteria and viruses, but it is detrimental to human-beings as well. So, for the purpose of disinfection without human interference, a UV Robot has been designed and implemented that follows a pre-defined path. It was equipped with three 20W UV lamps which radiates light in all directions. Given that UV light can be dangerous to humans, an embedded system based on Arduino along with PIR sensors are employed on top of the robot that detects human or animal’s motion and presence. So, one of the effective ways to avoid getting infected with SARS-COV-2 (Corona virus) is by sterilizing rooms using UV robot.

Then, we present the PHY and MAC layers of the technologies that are already deployed, or likely to be deployed: UNB by SigFox, CSS by LoRaTM,Weighless, and RPMA by Ingenu. We then compare their performances to highlight their pros and cons. Finally, we discuss on the open research challenges that still need to be addressed.

mobile robot. The two main challenging aspects of mobile robotics are to achieve localization and navigation.
Localization determines the location of the robot with respect to its environment. Navigation is the movement of
the robot from one location to the other. Here, the unique design and representation of the QR code helped us to
localize and navigate the robot. A raspberry pi mounted with a camera is used to interface with the robot. The
triangulation method is used to localize the robot. Dijkstra’s algorithm is used to compute the shortest path from
source to destination. The system is monitored tested based on the feedback system established by the Hologram
cellular USB modem. Experimental results show that this approach has good feasibility and effectiveness. The
robot navigates through the shortest path, performs specified tasks, and returns to its source.

The assumption is as follows: In a single Fog server, high traffic coming from Things may cause packet loss which in turn affect the overall IoT performance. To overcome such a situation, LB on Fog layer is proposed and implemented practically using virtualization technology. The proposed IoT based Fog-To-Cloud and Data-inMotion with LB (IoT-F2CDM-LB) architecture consists of two load balancers; HAProxy and Server Load Balancing (SLB), are used to distribute messages from Things to four virtualized Fog servers according to Least Connection technique. The implementation is carried out using VirtualBox and GNS3. Message Queue Telemetry Transport (MQTT) protocol is used to transfer messages between layers. Both load balancers result in packet loss reduction by 50%, lower response time and higher throughput.

While such deployments in African environments have a major advantage of abundant sunshine, both in intensity and duration, the same environments still present a number
of unique challenges. With the various research initiatives in Africa being quite disjointed, a major problem is the lack of a unified knowledge base that communicates the current challenges and solutions in designing power systems for these WSNs. We implemented a WSN with several autonomous sensors and two types of gateways. We kept track of voltages, uptime and other diagnostic data. We combine our experiences from the study of these devices, and those of some others in the region and other developing countries and make recommendations where we have achieved good results and propose solutions where work is still in progress.

So many researchers have dealt with and put their effort into this problem, as a result, several types of approaches have developed. Currently using traffic monitoring and alert systems are not up to the needs of smart city applications and more expensive. This paper proposes an Internet of Things (IoT) based Smart Real-Time Traffic Monitoring System to provide better service with low cost for Smart city applications using semantic annotations. The proposed framework contains two phases namely-traffic monitoring unit and traffic reduction unit. The first phase analyses semantic traffic to detect an emergency, the latter phase removes redundant semantic information for traffic reduction. Simulation results suggest that the framework is capable of accurate and early detection of an emergency as well as traffic reduction while keeping sufficient information to report the emergency.

extremely large variety of devices, link layer technologies, and services that may be involved in such a
system. In this paper, we identify the main blocks of a generic IoT architecture, describing their features
and requirements, and analyze the most common approaches proposed in the literature for each block. In
particular, we compare three of the most important communication technologies for IoT purposes, i.e., REST,
MQTT, and AMQP, and we also analyze three IoT platforms: openHAB, Sentilo, and Parse. The analysis will
prove the importance of adopting an integrated approach that jointly addresses several issues and is able to
flexibly accommodate the requirements of the various elements of the system. We also discuss a use case which
illustrates the design challenges and the choices to make when selecting which protocols and technologies to
use.
