  • Iot: the Age of Machine
    International Journal of Engineering Research and General Science Volume 3, Issue 6, November-December, 2015 ISSN 2091-2730 IoT: The Age of Machine Dharam J. Gami Atmiya Institute of Technology and Science, Gujarat Technological University, Gujarat Email: [email protected] Abstract— IoT is not just a technology but it is an ideology or a concept which leads to a new age that is age of machine. IoT is the key to fully digitalize the world. Move towards IoT will revolutionise human life where machine-to-machine communication is emphasized and human interaction is minimized. IoT demands everything on internet and be controlled and managed by machine itself. The goal of this paper is to give an imagination and a Skelton of IoT. This paper also highlights the challenges in IoT implementation and other critical issues. Keywords— IoT, age of machine, smart objects, IoT challenges, automation, architecture, open loop, RFID. INTRODUCTION The term IoT was first coined by Kevin Ashton in 1992 [7]. IoT don’t have any exact or wildly accepted definition. We can explain IoT by saying that ―IoT is a network of things, where thing refers to a smart object. Objects are embedded with electronics, software, sensors, and network connectivity, which enable these objects to collect and exchange data [7]. The idea is to connect every object via Internet and make them communicate. IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications (M2M) and covers a variety of protocols, domains, and applications [12]. To do so, creating a new framework, infrastructure or technology is not feasible.

    Service Composition for IP Smart Object using Realtime Web Protocols: Concept and Research Challenges Son N. Hana,∗, Imran Khana,c, Gyu Myoung Leeb, Noel Crespia, Roch H. Glithoc aTelecom SudParis, 9 Charles Fourier, 91011 Evry, France bLiverpool John Moores University, Byrom Street, Liverpool, L3 3AF, UK cConcordia University, 1515 St Catherine Street West, Montreal, Quebec Canada H3G 2W1 Abstract The Internet of Things (IoT) refers to a world-wide network of interconnected physical things using standardized communication protocols. Recent develop- ment of Internet Protocol (IP) stacks for resource-constrained devices unveils a possibility for the future IoT based on the stable and scalable IP technol- ogy much like today's Internet of computers. One important question remains: how can data and events (denoted as services) introduced by a variety of IP networked things be exchanged and aggregated efficiently in various application domains. Because the true value of IoT lies in the interaction of several services from physical things, answers to this question are essential to support a rapid creation of new IoT smart and ubiquitous applications. The problem is known as service composition. This article explains the practicability of the future full-IP IoT with realtime Web protocols to formally state the problem of service composition for IP smart objects, provides literature review, and discusses its research challenges.

Received: 30 March 2020; Accepted: 13 May 2020; Published: 14 May 2020 Abstract: Smart cities follow different strategies to face public health challenges associated with socio-economic objectives. Buildings play a crucial role in smart cities and are closely related to people’s health. Moreover, they are equally essential to meet sustainable objectives. People spend most of their time indoors. Therefore, indoor air quality has a critical impact on health and well-being. With the increasing population of elders, ambient-assisted living systems are required to promote occupational health and well-being. Furthermore, living environments must incorporate monitoring systems to detect unfavorable indoor quality scenarios in useful time. This paper reviews the current state of the art on indoor air quality monitoring systems based on Internet of Things and wireless sensor networks in the last five years (2014–2019).

  • Freedom and Privacy in Ambient Intelligence,’ Ethics and Information Technology 7(3), 157-166
    This is a preprint version of the following article: Brey, P. (2006). ‘Freedom and Privacy in Ambient Intelligence,’ Ethics and Information Technology 7(3), 157-166. Freedom and Privacy in Ambient Intelligence Abstract This paper analyzes ethical aspects of the new paradigm of Ambient Intelligence, which is a combination of Ubiquitous Computing with Intelligent User Interfaces. After an introduction to the approach, two key ethical dimensions will be analyzed: freedom and privacy. It is argued that Ambient Intelligence, though often designed to enhance freedom and control, has the potential to limit freedom and autonomy as well. Ambient Intelligence also harbors great privacy risks, and these are explored as well. Keywords Ambient Intelligence, Ubiquitous Computing, Intelligent User Interfaces, smart objects, invisible computers, freedom, autonomy, privacy THE PROMISE OF AMBIENT INTELLIGENCE Envision the following scenario: A young mother is on her way home, driving together with her 8-month old daughter who is sleeping in her child seat on the passenger side of the car. The infant is protected by an intelligent system called SBE 2 against airbag deployment, which could be fatal in the case of an accident. SBE 2 detects when there is a child seat on the passenger seat instead of a person and automatically disables the airbag (...) Arriving home, a surveillance camera recognizes the young mother, automatically disables the alarm, unlocks the front door as she approaches it and turns on the lights to a level of brightness that the home control system has learned she likes. After dropping off her daughter, the young mother gets ready for grocery shopping.

The implementation of Internet of Things (IoT) in the healthcare ecosystem has been one of the best solutions to address these challenges and therefore to prevent and diagnose possible health impairments in people. The remote monitoring of environmental parameters and how they can cause or mediate any disease, and the monitoring of human daily activities and physiological parameters are among the vast applications of IoT in healthcare, which has brought extensive attention of academia and industry. Assisted and smart tailored environments are possible with the implementation of such technologies that bring personal healthcare to any individual, while living in their preferred environments. In this paper we address several requirements for the development of such environments, namely the deployment of physiological signs monitoring systems, daily activity recognition techniques, as well as indoor air quality monitoring solutions. The machine learning methods that are most used in the literature for activity recognition and body motion analysis are also referred.

(Tech.) Jari Arkko, Licentiate (Tech.) Internet of Things (IoT) refers to an inter-connected world where physical devices are seamlessly integrated into the Internet and become active participants of business, information and social processes. This involves the inter-connection of a large number of heterogeneous networked entities and networks. Emergence of technologies such as Zigbee, Bluetooth low energy and embedded sensors has transformed simple physical devices into smart objects that can understand and react to their environment. Such smart objects form the building blocks for the Internet of Things. The communication infrastructure for these objects is based on an extension of the Internet protocol stack. Although the need for security is widely accepted, there is no clear consensus on how IP-based Internet security protocols can be applied to resource-constrained smart object networks. In this thesis, we develop a new secure and energy- efficient communication model for the Constrained Application Protocol (CoAP), a light-weight communication protocol designed for smart object networks.

  • Smart Objects: the “Things” in Iot
    Smart Objects: The “Things” in IoT Module 2 Sensors are fundamental building blocks of IoT networks Sensors are the foundational elements found in smart objects—the “things” in the Internet of Things Smart objects are any physical objects that contain embedded technology to sense and/or interact with their environment in a meaningful way by being interconnected and enabling communication among themselves or an external agent. SENSORS, ACTUATORS, AND SMART OBJECTS A sensor: It senses More specifically, a sensor measures some physical quantity and converts that measurement reading into a digital representation. That digital representation is typically passed to another device for transformation into useful data that can be consumed by intelligent devices or humans Sensors are not limited to human-like sensory data. They are able to provide an extremely wide spectrum of rich and diverse measurement data with far greater precision than human senses Categories Active or passive: Sensors can be categorized based on whether they produce an energy output and typically require an external power supply (active) or Whether they simply receive energy and typically require no external power supply (passive). Invasive or non-invasive: Sensors can be categorized based on whether a sensor is part of the environment it is measuring (invasive) or External to it (non-invasive). Contact or no-contact: Sensors can be categorized based on whether they require physical contact with what they are measuring (contact) or not (no-contact). Absolute or relative: Sensors can be categorized based on whether they measure on an absolute scale (absolute) or based on a difference with a fixed or variable reference value (relative).
