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.

However digital divide has been of concern as developed countries have been benefiting more than their developing counterparts. All that resulting from lack of skilled labour and finance to invest into the required technology. This case study focused on the survival of the developing countries as they are constrained by the financial challenges. Three major dimensions from the socio-technical perspective of systems dimensions guided the authors in the study. The study showed the ability of people in developing countries to adapt to the challenging environment as they strive to cultivate from the strengths of ICT. This is particularly within Small and Medium Enterprises. Primary to this adaptation is the use of local expertise to develop own system than relying on imports from developed countries.

Main precondition for active participation in the daily living and needs of visually impaired persons is increased degree of mobility. The aim of this research is to increase the quality of life of visually impaired persons and the degree of mobility in indoor environments by applying modern information and communication technologies (Cloud Computing, Fog, IoT, AAL / ELE platform). User requirement will be used to define functionalities of service for informing visually impaired persons in the example of large retail chains. A conceptual system architecture model will be proposed for providing information service with the aim to provide real-time information to users. This research will also show simulation testing of the proposed architecture with Arduino Uno and Raspberry Pi 3 platforms for collecting information and informing end users.

The authentication towards multiple devices has become the research hot-spot considering of the requirement in real applications. Sensitivity and privacy of data have caused widespread concerns because low-cost devices are neither tamper-proof nor capable of performing public key cryptography efficiently. However, many researchers only focus on the authentication between two devices in the network. They ignore the authentication among group devices attached to one network. In this paper, we propose A Practical Group Authentication Scheme for Smart Devices in IoT. Note that one device group to be authenticated consists of a group of smart devices. The personal digital assistant (PDA) as the group leader controls authentication operations in its group. From the security analysis, our scheme can resist to various attacks. In addition, the performance analysis shows that our scheme has lower computational cost than the existing scheme.

Connected devices will produce approximately 44 ZB of raw data by 2020, which provides interesting challenges relatively to privacy, connectivity, and scalability. The Internet of Things (IoT) is earning growing attention that provides the interconnection between the physical and the digital world. Consequently, the physical world needs to be measured and converted into expressible statistics. Cloud for IoT introduces precious application and unique services in several domains. However, fog computing helps in efficient utilization and better performance in case of bandwidth utilization, and low power consumption. This review focuses on the IoT platforms used for fog and cloud computing to serve IoT end-to-end services. In addition, the application of the cloud of thing and fog roles to improve the challenges of the cloud of things are also provided.

These AWSs face challenges, which lower their performance. Hence, a need for regular monitoring to reduce down time. We propose condition monitoring, comprised of a data receiver, analyser, problem classifier and reporter and visualizer, to mine data relationships, identify possible causes of problems and perform reporting of AWS status. The data receiver uses an M/M/1/k queuing model. We use Successive Pairwise REcord Differences (SPREDs) algorithm to compare arrival rates and packet content so as to establish sensor, node and AWS level performance. We also perform a hybrid of Grubb outlier detection and correlations amongst related variables for data validation. Problems take on one of four states. One connection can receive data at a rate as low as 1ms, without loss while problem identification especially in high density network is improved.

The major issue with available platforms is that they view Things as private property. But this view is short sighted. A Thing should be viewed as a service or a functionality provider. The Thing owner should be able to publish Thing information and make it public. On the other hand, Thing requesters should be able to discover available Things. Our research is concerned with introducing an architecture that supports the publication and discovery of Things. This architecture will enable Thing owners to publish Thing speciﬁcation and Thing requesters to ﬁnd Things that best matches their needs. The main contribution of this paper is an SOA Context-aware Architecture for the publication and discovery of Things. This paper formally deﬁnes an architecture for Things and queries. Also, this paper presents two XML languages that supports the publication and query of Things.

Researchers trust that IoT services deployment by Telecom is inevitable during the next few years. Nowadays, digital development overgrows, thus Telecom operators should consider IoT as the next evolution in their business plans. If an operator’s services confined to traditional services such as calling, they will lose a lot of added values and opportunities. In the end, they will find themselves out of the competition. Recently, the research community has addressed this topic and enriched it by highlighting related issues to help operators and researchers to move forward in this field. This paper presents a sound review for this topic covering the most significant related issues such as success elements, strategies and Low-Power Wide-Area (LPWA) standards provided by Telecom operators for IoT provision.

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.

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.

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

data about the environment. These initiatives are usually referred to as grassroots and are driven by a vision of widening
access to tools for political action. In this paper we compare patterns of participation and user experience over 15 months
in two distinct communities using ‘Smart Citizen’, a crowdfunded IoT participatory sensing tool. Our studies reveal that
technology issues and a lack of reliability of the sensed data hindered user participation. However, in one of the
communities, many of these challenges were overcome through orchestrated actions led by community champions. We
discuss how crowdfunding doesn’t necessarily translate into active participation and provide guidelines on how to achieve
sustained engagement in crowdfunded IoT community sensing projects: enable distributed orchestration provided by local
champions, encourage social interactions that embed skills and learning, and facilitate meaningful participation and reward
mechanisms among community members.

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.
