The
number of smart devices is continuously increasing. The expanding network of interconnected devices provided an
impetus for rapid advancement in the domain of Internet-of-Things (IoT). IoT has recently become a centre of attraction
for research community. The development of microprocessors and microcontrollers has supplemented advancement in IoT
paradigm. The rapidly emerging paradigm of IoT is facing challenges which render significant impact on its performance
and cost.

OBJECTIVES: In this paper, a novel architecture based on Real-Time Database System (RTDBS) coupled with cloud
functionalities is proposed for providing efficient and cost-effective IoT system. An efficient circuit design consisting of
solid state technology has also been integrated with the proposed architecture for enhancing the feasibility of the model.

METHODS: The proposed model leverages cloud-hosted RTDBS for developing IoT system. After an inspective analysis,
the most appropriate RTDBS was selected. In this model, a User Interface (UI) is coupled with the selected RTDBS. The
same RTDBS is connected with ESP8266 which is directly attached with switching circuit based on a proposed design.
The UI is also retrofitted with the functionality of recognizing speech in both English and Urdu. After speech recognition,
corresponding command is sent to RTDBS and RTDBS updates the relevant instance. The modification of state generates
a signal that is sent to ESP8266, and ESP8266 triggers the switching circuit according the signal received from RTDBS.

RESULTS: The proposed IoT system was implemented and tested for continuous switching transactions and it purported
to be highly tolerant against the threat of malfunctioning which arises due to continuous switching operations. The
implemented IoT system was subjected to voice commands both in English and Urdu, and it exhibited the quick responses.

CONCLUSION: The results obtained from the scrutiny of implementation endorse the efficiency of proposed model.

Oﬄoading applications from the cloud to the edge of the network can eﬀectively diminish the latency of users waiting for applications to improve their quality of service(QoS). Due to the user mobility, however, the distance between the user and the edge device is constantly increasing, resulting in a degradation of the user’s QoS. To satisfy the QoS of mobile users, applications should be dynamically migrated to follow the user mobility. In this paper, we propose a mobility-aware dynamic service placement policy that reduces the number of virtual machine migrations and diminishes user-perceived latency simultaneously. The proposed scheme ﬁlters out the invalid migration that the user handoﬀs to another access point before the migration is completed. The simulation trials demonstrate that our solution improves the QoS of users and reduces the number of application migrations.

A type of LPWA device called a sub-GHz band communication device allows a 1-hop wide area communication system to have improved power consumption. However, a sub-GHz band communication system is not scalable due to the lack of compatibility with heterogeneous communication devices, such as WiFi and LTE. In this paper, we propose a sub-GHz band communication bridge that builds a cross-over communication system connecting a conventional TCP/IP network and LPWA network. The communication bridge enables scalable TCP/IP network services (e.g., HTTP) by transmitting an ethernet frame over an LPWA network. Through experiments using IM920, a dedicated device for 920 MHz band communication, we evaluated the performance and behavior of communication through TCP applications over a TCP/IP network and LPWA network connected by the proposed communication bridge.

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.

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.

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

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.

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.
