Optimization of flat area coverage under connectivity constraint in wireless sensor networks
2022
A wireless sensor network consists of a set of small autonomous units that interact via a network built by their communication modules. They observe their environment, capture information, then manage this information according to their computing and/or storage capacity. To effectively accomplish their task(s), they need to cover as much of the area of interest as possible. It is therefore essential to quantify the quality of their coverage. In this thesis, we therefore seek to best cover an area of interest, with a precise number of sensors. While taking into account the possible overlaps between sensors, we first deploy in a zone of regular dimensions and evaluate the exact coverage using…
Consumer Acceptance Determinants of Internet of Things : A New Perspective
2018
International audience; Despite the rising popularity of Internet of Things (IoT), consumer acceptance continues to grow at a slow pace. For example, adoption of health and fitness wearables is still relatively low and about a half of consumers abandon their wearables within the first six months. This pattern means that firms engaged in IoT industry can not recover their development and marketing costs. Recent research offer a fragmented view of the determinants of IoT consumer acceptance and focus mainly on functional attributes.This paper aims to provide a new perspective. Drawing on the service-dominant logic, the perceived value conceptualization and the customer experience approach, ou…
Design and Implementation of Real-Time Kitchen Monitoring and Automation System Based on Internet of Things
2022
Automation can now be found in nearly every industry. However, home automation has yet to reach Pakistan. This paper presents an Internet of Things smart kitchen project that includes automation and monitoring. In this project, a system was developed that automatically detects the kitchen temperature. It also monitors the humidity level in the kitchen. This system includes built-in gas detection sensors that detect any gas leaks in the kitchen and notify the user if the gas pressure in the kitchen exceeds a certain level. This system also allows the user to remotely control appliances such as freezers, ovens, and air conditioners using a mobile phone. The user can control gas levels using t…
Next Generation Home Sharing: Disrupting Platform Organizations with Blockchain Technology and the Internet of Things?
2020
During the last decade, the sharing economy has given birth to a number of market mediators, which have grown to become the world’s most valuable companies. Centralized sharing platforms like Uber, Didi Chuxing, and Airbnb have transformed several traditional industries. However, with the rise of the blockchain technology, some voices predict that these platform companies will soon be at risk of being disrupted themselves. In this chapter, we address the question of whether blockchain technology has given birth to a new breed of sharing economy platforms that can challenge the incumbents’ business models. We identify five different stages of the application of blockchain technology in emerg…
Guises and their Existence
1996
According to H-N. Castafieda, a guise the very thin individual which lies at the bottom of the ontological furniture of the world is indifferent to existence in a Meinongian way, in the sense that it remains the same whether it exists or not. Moreover, its existence does not alter its intentional character, as it is the very same individual which is thought of regardless of its being real or not. ~ In what follows, I will attempt to show that with regards to guises both theses are illegitimate, unless one introduces the notion of an existentiallyconditioned property as a counterfactual property which a guise has prior to its actual existence. To do so means to work out an amendment to Casta…
A framework for evaluating Internet-of-Things platforms: Application provider viewpoint
2014
Widespread adoption of Internet of Things (IoT) applications assumes a sustainable ecosystem of firms creating, distributing, and using these applications. Such an ecosystem often forms around a platform that implements commonly used functionality and offers it to the members of the ecosystem for creating applications and services. In IoT, such a platform may be materialized in a form of a cloud platform that supports the management of connected devices, and the development and use of the applications based on them. A number of cloud platforms targeting IoT applications are available in the market; to prosper, they need to assist the providers of the IoT applications in designing and develo…
Cyber Security and the Internet of Things: Vulnerabilities, Threats, Intruders and Attacks
2015
Internet of Things (IoT) devices are rapidly becoming ubiquitous while IoT services are becoming pervasive. Their success has not gone unnoticed and the number of threats and attacks against IoT devices and services are on the increase as well. Cyber-attacks are not new to IoT, but as IoT will be deeply interwoven in our lives and societies, it is becoming necessary to step up and take cyber defense seriously. Hence, there is a real need to secure IoT, which has consequently resulted in a need to comprehensively understand the threats and attacks on IoT infrastructure. This paper is an attempt to classify threat types, besides analyze and characterize intruders and attacks facing IoT device…
Medical Data Processing and Analysis for Remote Health and Activities Monitoring
2019
Recent developments in sensor technology, wearable computing, Internet of Things (IoT), and wireless communication have given rise to research in ubiquitous healthcare and remote monitoring of human’s health and activities. Health monitoring systems involve processing and analysis of data retrieved from smartphones, smart watches, smart bracelets, as well as various sensors and wearable devices. Such systems enable continuous monitoring of patients psychological and health conditions by sensing and transmitting measurements such as heart rate, electrocardiogram, body temperature, respiratory rate, chest sounds, or blood pressure. Pervasive healthcare, as a relevant application domain in thi…

A Digital Twin predictive maintenance framework of air handling units based on automatic fault detection and diagnostics
2022
The building industry consumes the most energy globally, making it a priority in energy efficiency initiatives. Heating, ventilation, and air conditioning (HVAC) systems create the heart of buildings. Stable air handling unit (AHU) functioning is vital to ensuring high efficiency and extending the life of HVAC systems. This research proposes a Digital Twin predictive maintenance framework of AHU to overcome the limitations of facility maintenance management (FMM) systems now in use in buildings. Digital Twin technology, which is still at an initial stage in the facility management industry, use Building Information Modeling (BIM), Internet of things (IoT) and semantic technologies to create…
