Mining of High-Utility Patterns in Big IoT-based DatabasesWu, Jimmy M. T., Srivastava, Gautam, Lin, Jerry C., Djenouri, Youcef, Wei, Min, Parizi, Reza M., Khan, Mohammad S. 01 February 2021 (has links)
When focusing on the general area of data mining, high-utility itemset mining (HUIM) can be defined as an offset of frequent itemset mining (FIM). It is known to emphasize more factors critically, which gives HUIM its intrinsic edge. Due to the flourishing development of the IoT technique, the uncertainty patterns mining is also attractive. Potential high-utility itemset mining (PHUIM) is introduced to reveal valuable patterns in an uncertainty database. Unfortunately, even though the previous methods are all very effective and powerful to mine, the potential high-utility itemsets quickly. These algorithms are not specifically designed for a database with an enormous number of records. In the previous methods, uncertainty transaction datasets would be load in the memory ultimately. Usually, several pre-defined operators would be applied to modify the original dataset to reduce the seeking time for scanning the data. However, it is impracticable to apply the same way in a big-data dataset. In this work, a dataset is assumed to be too big to be loaded directly into memory and be duplicated or modified; then, a MapReduce framework is proposed that can be used to handle these types of situations. One of our main objectives is to attempt to reduce the frequency of dataset scans while still maximizing the parallelization of all processes. Through in-depth experimental results, the proposed Hadoop algorithm is shown to perform strongly to mine all of the potential high-utility itemsets in a big-data dataset and shows excellent performance in a Hadoop computing cluster.

A unified framework for real-time streaming and processing of IoT dataZamam, Mohamad January 2017 (has links)
The emergence of the Internet of Things (IoT) is introducing a new era to the realm of computing and technology. The proliferation of sensors and actuators that are embedded in things enables these devices to understand the environments and respond accordingly more than ever before. Additionally, it opens the space to unlimited possibilities for building applications that turn this sensation into big benefits, and within various domains. From smart cities to smart transportation and smart environment and the list is quite long. However, this revolutionary spread of IoT devices and technologies rises big challenges. One major challenge is the diversity in IoT vendors that results in data heterogeneity. This research tackles this problem by developing a data management tool that normalizes IoT data. Another important challenge is the lack of practical IoT technology with low cost and low maintenance. That has often limited large-scale deployments and mainstream adoption. This work utilizes open-source data analytics in one unified IoT framework in order to address this challenge. What is more, billions of connected things are generating unprecedented amounts of data from which intelligence must be derived in real-time. This unified framework processes real-time streams of data from IoT. A questionnaire that involved participants with background knowledge in IoT was conducted in order to collect feedback about the proposed framework. The aspects of the framework were presented to the participants in a form of demonstration video describing the work that has been done. Finally, using the participants’ feedback, the contribution of the developed framework to the IoT was discussed and presented.

Seeking opportunities in the Internet of Things (IoT): : A Study of IT values co-creation in the IoT ecosystem while considering the potential impacts of the EU General Data Protection Regulations (GDPR).Ford, David Thomas, Qamar, Sreman January 2017 (has links)
In this thesis, we have studied the phenomena of value co-creation in IoT ecosystem, while considering the potential impacts of GDPR on IT value co-creation in the IoT ecosystem. IT firms’ ability to create value is an important aspect of their existence and growth in which case they pursuit different and several means to accomplish this task. IT firms that operate within the IoT ecosystem are categorised as Enablers, Engagers, and Enhancers who interact, work together to provide the technology and services needed to both market the IoT and to deploy it for their own business operations. These actors usually deem it necessary to create value through a co-creation process with customers in order to create well needed, tailored and up-to-date IoT solutions. In such case, customers’ data play a significant role in the development process. Through computer analysis, these data can reveal insightful information that can lead to the creation of relevant and appropriate IT solutions. However, the EU new and upcoming General Data Protection Regulation stand to have some impacts on this creative process, by regulating data practices in technological activities, thereby, creating several concerns among the IT community.

Ontology-based discovery of time-series data sources for landslide early warning systemPhengsuwan, J., Shah, T., James, P., Thakker, Dhaval, Barr, S., Ranjan, R. 15 July 2019 (has links)
Yes / Modern early warning system (EWS) requires sophisticated knowledge of the natural hazards, the urban context and underlying risk factors to enable dynamic and timely decision making (e.g., hazard detection, hazard preparedness). Landslides are a common form of natural hazard with a global impact and closely linked to a variety of other hazards. EWS for landslides prediction and detection relies on scientific methods and models which requires input from the time series data, such as the earth observation (EO) and urban environment data. Such data sets are produced by a variety of remote sensing satellites and Internet of things sensors which are deployed in the landslide prone areas. To this end, the automatic discovery of potential time series data sources has become a challenge due to the complexity and high variety of data sources. To solve this hard research problem, in this paper, we propose a novel ontology, namely Landslip Ontology, to provide the knowledge base that establishes relationship between landslide hazard and EO and urban data sources. The purpose of Landslip Ontology is to facilitate time series data source discovery for the verification and prediction of landslide hazards. The ontology is evaluated based on scenarios and competency questions to verify the coverage and consistency. Moreover, the ontology can also be used to realize the implementation of data sources discovery system which is an essential component in EWS that needs to manage (store, search, process) rich information from heterogeneous data sources.

An ontology-based system for discovering landslide-induced emergencies in electrical gridPhengsuwan, J., Shah, T., Sun, R., James, P., Thakker, Dhaval, Ranjan, R. 07 April 2020 (has links)
No / Early warning systems (EWS) for electrical grid infrastructure have played a significant role in the efficient management of electricity supply in natural hazard prone areas. Modern EWS rely on scientific methods to analyze a variety of Earth Observation and ancillary data provided by multiple and heterogeneous data sources for the monitoring of electrical grid infrastructure. Furthermore, through cooperation, EWS for natural hazards contribute to monitoring by reporting hazard events that are associated with a particular electrical grid network. Additionally, sophisticated domain knowledge of natural hazards and electrical grid is also required to enable dynamic and timely decision‐making about the management of electrical grid infrastructure in serious hazards. In this paper, we propose a data integration and analytics system that enables an interaction between natural hazard EWS and electrical grid EWS to contribute to electrical grid network monitoring and support decision‐making for electrical grid infrastructure management. We prototype the system using landslides as an example natural hazard for the grid infrastructure monitoring. Essentially, the system consists of background knowledge about landslides as well as information about data sources to facilitate the process of data integration and analysis. Using the knowledge modeled, the prototype system can report the occurrence of landslides and suggest potential data sources for the electrical grid network monitoring. / FloodPrep, Grant/Award Number: (NE/P017134/1); LandSlip, Grant/Award Number: (NE/P000681/1)

The Impact of Internet of Things unification with Project Management Disciplines in project-based organizationsPercudani, Pietro, Batrawi, Mohamad January 2017 (has links)
The greatest advantage of Information Technology (IT) is its ability in entitling personnel to achieve their goals. Allowing personnel to grasp knowledge and skills they weren’t aware of previously, rendering to a sense that it’s all about potential; as expressed by former CEO of Microsoft Steve Ballmer. Internet of Things (IoT) data, according to ORACLE (2017), provides insight from new data collected and provides solutions. Thus, allowing businesses to achieve new innovative services at a more efficient and productive manner while reducing the risk factors. Proving that the connections between the organisation and devices are securely connected, analysed, and integrated simultaneously with IoT data. Project Management (PM) the leading discipline in management that benefits enterprises through actual and operative management of change through its systematic approach of initiating, planning, executing, monitoring & controlling, Testing & Commissioning and finally Handing Over to the client the project; managing various types of projects with various drivers of change and uncertainty. (Sawyer, L. 2016). As significant as technology has become in our lives, this study aims in highlighting the importance of Internet of Things and the synergic implementation of Project Management disciplines in project-oriented organisations. It also explores the challenges, barriers, and benefits of IoT in synergy with PM disciplines.

Internet of Things and Cybersecurity in a Smart HomeKiran Vokkarne (17367391) 10 November 2023 (has links)
<p dir="ltr">With the ability to connect to networks and send and receive data, Internet of Things (IoT) devices involve associated security risks and threats, for a given environment. These threats are even more of a concern in a Smart Home network, where there is a lack of a dedicated security IT team, unlike a corporate environment. While efficient user interface(UI) and ease of use is at the front and center of IoT devices within Smart Home which enables its wider adoption, often security and privacy have been an afterthought and haven’t kept pace when needed. Therefore, a unsafe possibility exists where malicious actors could exploit vulnerable devices in a domestic home environment.</p><p dir="ltr">This thesis involves a detailed study of the cybersecurity for a Smart Home and also examines the various types of cyberthreats encountered, such as DDoS, Man-In-Middle, Ransomware, etc. that IoT devices face. Given, IoT devices are commonplace in most home automation scenarios, its crucially important to detect intrusions and unauthorized access. Privacy issues are also involved making this an even more pertinent topic. Towards this, various state of the art industry standard tools, such as Nmap, Nessus, Metasploit, etc. were used to gather data on a Smart Home environment to analyze their impacts to detect security vulnerabilities and risks to a Smart Home. Results from the research indicated various vulnerabilities, such as open ports, password vulnerabilities, SSL certificate anomalies and others that exist in many cases, and how precautions when taken in timely manner can help alleviate and bring down those risks.</p><p dir="ltr">Also, an IoT monitoring dashboard was developed based on open-source tools, which helps visualize threats and emphasize the importance of monitoring. The IoT dashboard showed how to raise alerts and alarms based on specific threat conditions or events. In addition, currently available cybersecurity regulations, standards, and guidelines were also examined that can help safeguard against threats to commonly used IoT devices in a Smart Home. It is hoped that the research carried out in this dissertation can help maintain safe and secure Smart Homes and provide direction for future work in the area of Smart Home Cybersecurity.</p>
