However, those algorithms are known to be unstable and inefficient when the network size is high. Since recently, a Distributed Queuing (DQ) algorithm is being proposed as a solution to mitigate several of the Aloha issues in IoT networks. In this paper, a statistical performance analysis of the DQ algorithm without any prior consideration of any physical layer is presented. We evaluate the DQ algorithm in a massive communication environment and give the average values for these performance metrics: collision resolution time, access delay per sensor, channel throughput, number of attempts required by a sensor to complete the contention process, number of nodes contending per frame and the distribution of contention slots into idle, successful, and collided. The goal of this paper is to provide a statistical baseline performance evaluation of the DQ algorithm in general.

Examples of i-construction include remote and automatic control systems for construction machinery, for which wireless communication is generally required; however, the wireless characteristics that must be considered in i-construction remain unclear. To clarify these characteristics, Bluetooth Low Energy (BLE) beacon module is implemented for construction machines, and we investigate its communication characteristics. We focussed on two evaluations: characterisation of the BLE unit module and its feasibility in i-construction. Experimental results were used to characterise BLE communication in a residential area and construction site. In the latter, BLE beacon module communication was possible between a sender located in an excavator attachment and a receiver in its cabin.

Moreover, the communication between the cluster head (CH) and the base station(BS) in a hierarchical WSN is required to be more secure since the CH is responsible for data collection, aggregation and its forwarding to the BS. Thus, this paper aims to design a hybrid key management scheme (KMS) for the hierarchical WSNs for enhancing security between the CH and BS by using some asymmetric cryptographic technique while applying the secret key based communication among the member nodes to reduce their computational overheads. The security analysis of our proposed scheme exhibits its robustness against the node capture attack and its ability to support the node revocation. The performances of proposed scheme are also evaluated in term of data freshness, average number of keys established, throughput and computational cost to demonstrate its efficiency.

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.

However, these conventional emergency services are not equipped with appropriate equipment to provide high QoS. For instance, conventional medical emergency services include ambulances with drivers and oxygen supplies only. Another example is the conventional fire control systems that only include fire control truck, which is not suitable for current scenario due to various challenges, for instance, road traffic. In addition, accidental services are unsatisfactory in current and future emergency services. Emergency service is required by anyone at anytime and anywhere. Therefore, it is the time to redefine and restructure the conventional emergency service for saving more lives. Due to the advent of wireless communication technology, it is possible to provide the emergency service on the spot in nearly real-time to save lives. Moreover, integration of Artificial Intelligence with smart devices can change the definition of emergency services. In this chapter, we envision the various emergency services to advance the healthcare services. Besides, we envision the impact of emergency services on healthcare with the help of Artificial Intelligence, 5G and 6G communication technology.

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.

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.

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.

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

Many researchers and experts in the field share the opinion that the next-to-come fifth generation (5G) cellular systems will be a strong boost for the IoT deployment. Device-to- Device (D2D) appears as a key communication paradigm to support heterogeneous objects interconnection and to guarantee important benefits. In this paper, we thoroughly discuss the added-value features introduced by cellular/noncellular D2D communications and its potential in efficiently fulfilling IoT requirements in 5G networks. State-of-the-art solutions, enabling radio technologies, and current standardization activities for D2D communications are surveyed and their pros and cons with reference to manifold IoT use cases pointed out. Future research directions are then presented towards a fully converged 5G IoT ecosystem.
