location the information is meaningless. Most of the range-free algorithms have low localization accuracy, low cost, and
applications limited to indoor uses only. This paper proposes a Mobility Prediction localization algorithm using the Link
expiration time estimation method, this concept brings continuous link among the anchors and the mobile sensor nodes.
This gives more accurate position estimation (3.2% of R) and employs fewer samples (average 20.58 per slot) for the task,
hence results in less energy consumption than a Sequential Monte Carlo localization scheme. Both the algorithms are
studied, analyzed and compared with speed of the mobile nodes in terms of localization error (6.38% to 6.55% better on
different anchor density) communication cost (51.72% high), the number of samples taken per slot (average 58.8% less)
and residual energy profile.

mobile robot deployment is very cumbersome and constrained. Thus, the need arises for appropriate wireless technology
that may support the same or even better functionality. ZigBee is gaining popularity as supporting technology to facilitate
the working of mobile robots for search and rescue operations. This is because ZigBee based nodes utilize the industrial,
scientific, and medical frequency band that supports a data rate up to 250 kbps. This paper presents a packet forwarding
mechanism for ZigBee based mobile wireless sensor network nodes. The results achieved through the reported work shows
that the packet loss rate comes around to be 2 percent resulting in a 98 percent successful packet reception at the receiver

These potholes are dangerous for unsuspecting high-speed vehicles and results in multiple life-threatening accidents year-round. Apart from potholes, another severe concern about the time spent on roads is air pollution. Breathing the polluted air, mainly containing the particulate matter that has a diameter of fewer than 2.5 micrometers, is toxic to humans. In this work, we have judiciously designed an Internet of Things based smart helmet, which uses crowdsourcing to report potholes and collect crucial on-road air pollution data so that a person could avoid risk to life and health. We have also introduced the novel concept of remembrance factor and severity index, which could be useful in dealing with the stale and invalid pothole data in the database.

The use of water is used for various household needs for example for consumption, bathing,
washing and so on. At present there are still many people who use water pumps to fill water reservoirs at home or in office
buildings that are filled manually, so that problems often occur such as the level of water in the reservoir where water is
unknown, it is possible that the situation of reservoirs can occur overflow or empty. Utilizing technology in this research
will create a tool used to control the water level in the reservoir, which is "Microcontroller-Based Water Level Control
System and Android HMI" which is an alternative in controlling and monitoring the water level in a reservoir
automatically using an Android Smartphone. This tool is used to control and monitor water reservoirs automatically via Android
HMI so that it can be controlled remotely. This tool is designed using a NodeMCU ESP8266 Microcontroller, a relay module that
functions to turn on and turn off the pump, and one sensor, the HC-SR04 Ultrasonic Sensor which functions to measure the water level
in the reservoir. And the android application used is Cayenne. The test result data is shown in the cayenne application in the form of
setting the water height setpoint, the ON / OFF pump indicator and the height value in units of percent (%) and centimeter (cm).

Over time, live video streaming, real-time data and voice is being offered over hosted Clouds for business entertainment. Enterprise applications like Office 365, banking and e-commerce are
available over smartphones. With the advent of Fog Computing and Internet of Things, corporate enterprises and non-IT industries see potential in this technology. Billions of Internet-enabled devices, globally distributed nodes, embedded sensor
gateways transmit real-time generated over the internet to the cloud data centres. Cloud environments are not designed to handle this level of data that is being generated and Computing limits are being severely tested. Fog Computing has the potential to be the go-to option for Cloud service delivery.

OBJECTIVES: This paper reviewed existing research works and presents unique Smart Fog Computing based taxonomy. The authors also implemented experimental setup for Smart Cities using Smart Fog Computing for controlling Vehicular traffic.

METHODS: Smart Vehicular Management is viable use case for Fog and IoT technology. The authors designed and implemented two experimental setups. The first setup involvesstandard Cloud implementation and the second setup employs Fog Computing implemented using IoT Sensor nodes to compare the performance of the Vehicle Management Fog application regarding the Response time and Bandwidth Consumed. The architecture and implementation involved deploying 50 IoT sensors nodes across the university areas and routes.

RESULTS: The main results obtained in this paper are the following. As compared to Cloud computing, on deploying Fog Computing and IoT devices:
<ul>
<li> End-to-End Processing time dropped from 29.44 to 6.7 seconds → almost 77% less </li>
<li> Number of hops traversed reduced from 56 to 4 hops → almost 92% less </li>
<li> Bandwidth usage dropped from 247 to 8 kbps → almost 96.7% less </li>
</ul>
CONCLUSION: From the experimental setups as compared to Cloud computing, the Fog and IoT processes the traffic data locally on the edge devices, which reduces the end-to-end time.

Electrical energy becomes very dangerous if the user process is not equipped with a good protection system. Conventional overload protection devices, such as MCB, can cut off electricity only from load points and
cannot cut selective loads. Today's internet technology can be used not only for communication between individuals but also for communication between objects. By using the internet, devices can send data to each other and send requests to other devices. The Internet-based Smart Panel Is designed to protect components, and monitor the remote use of electrical energy
and control equipments via a smartphone. This tool uses NODEMCU and ESP12 for wireless communication. The PZEM004T sensor module is used as a current load reader.

The form captures most of the perceptual information of the observed objects on images in many applications, while colour and texture can often be omitted without affecting the performance of the retrieval. Unfortunately, there may be significant changes in shape, such as deformation, scaling, changes in orientation noise, and partial concealment. Accurate shape description remains, therefore, a challenging technical issue. The study performs experimental analysis to identify the problem. The adoption of the MPEG-7 and KIMIA-99 standard has significant importance to simplify the image retrieval process. The Fourier Descriptors, Moment-Based Features, Hierarchical Centroids and Histogram of Oriented Gradients have been applied for
extraction of images from datasets. The fusion of features has been done by Discriminant Correlation Analysis and Direct Concatenation of features it has been evident that by fusion of features we obtained approximately 90% accurate and better results.

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.

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

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

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.

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.
