Brush John Lach Accepted for the School of Engineering and Applied Science: Dean, School of Engineering and Applied Science December 2019 i To everyone who has helped me along the way. ii Abstract In the world today there exists a large number of problems that are of great societal concern, but suffer from a problem called the tragedy of the commons where there isn`t enough individual incentive for people to change their behavior to benefit the whole. One of the biggest examples of this is in energy consumption where research has shown that we can reduce 20-50% of the energy used in buildings if people would consistently modify their behavior. However, consistent behavior modification to meet societal goals that are often low priority on a personal level is often prohibitively difficult in the long term. Even systems design to assist in meeting these needs may be unused or disabled if they require too much effort, infringe on privacy, or are frustratingly inaccurate.

  • Ambient Intelligence
    Ambient intelligence Ambient intelligence is closely related to the long term vision of an intelligent service system in which technolo- gies are able to automate a platform embedding the re- quired devices for powering context aware, personalized, adaptive and anticipatory services. Where in other me- dia environment the interface is clearly distinct, in an ubiquitous environment 'content' differs. Artur Lugmayr defined such a smart environment by describing it as ambient media. It is constituted of the communication of information in ubiquitous and pervasive environments. The concept of ambient media relates to ambient media form, ambient media content, and ambient media tech- nology. Its principles have been established by Artur Lug- mayr and are manifestation, morphing, intelligence, and experience.[1][2] An (expected) evolution of computing from 1960–2010.

  • A. Define and Explain the Internet of Things
    IoT Solutions 1. Attempt any three of the following: a. Define and explain the Internet of Things. Ans: The Internet of things is defined as a paradigm in which objects equipped with sensors, actuators, and processors communicate with each other to serve a meaningful purpose. Equation of Internet of Things: Physical Object + Controllers, Sensors and Actuators + Internet = Internet of Things Physical Object: Devices, vehicles, buildings and other items which are embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. Controllers: A controller, in a computing context, is a hardware device or a software program that manages or directs the flow of data between two entities In a general sense, a controller can be thought of as something or someone that interfaces between two systems and manages communications between them. Sensors: Sensor is a device, module, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor. A sensor is always used with other electronics. Actuators: An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system. Internet: The internet is a globally connected network system that uses TCP/IP to transmit data via various types of media. The internet is a network of global exchanges – including private, public, business, academic and government networks – connected by guided, wireless and fiber-optic technologies. Example of Internet of Things: In your kitchen, a blinking light reminds you it’s time to take your tablets.

  • Core Concept: the Internet of Things and the Explosion of Interconnectivity
    CORE CONCEPTS The Internet of Things and the explosion of interconnectivity CORE CONCEPTS Stephen Ornes, Science Writer It was 1982, and a group of computer science graduate students at Carnegie Mellon University in Pittsburgh, Pennsylvania, was thirsty for more than knowledge: some wanted a Coca Cola. But the researchers were frustrated. The Coke machine was on the third floor of the university’s Wean Hall, and oftentimes they’d venture up to the dis- penser only to find it empty, or worse, full of warm soda. So the scientists connected the machine to the university’s computer network. By checking online, thirsty researchers could ensure the machine was stocked with cold bottles before visiting. This turned out to be more than an achieve- ment in efficient caffeine delivery; it’s thought to be one of the first noncomputer objects to go online (1). The notion of pervasive computing entails a vision of the world in which computing isn’t limited to tab- lets, smartphones, and laptops. The realization of this vision, called the “Internet of Things” (IoT), is the ever- expanding collection of connected devices that cap- ture and share data. Any object, outfitted with the right Pervasive computing and its realization, known as the “Internet of Things,” entails sensors, can observe and interact with its environment. an ever-expanding collection of connected devices that capture and share data.

  • From the Internet of Computers to the Internet of Things
    From the Internet of Computers to the Internet of Things Friedemann Mattern and Christian Floerkemeier Distributed Systems Group, Institute for Pervasive Computing, ETH Zurich {mattern,floerkem}@inf.ethz.ch Abstract. This paper1 discusses the vision, the challenges, possible usage sce- narios and technological building blocks of the “Internet of Things”. In particu- lar, we consider RFID and other important technological developments such as IP stacks and web servers for smart everyday objects. The paper concludes with a discussion of social and governance issues that are likely to arise as the vision of the Internet of Things becomes a reality. Keywords: Internet of Things, RFID, smart objects, wireless sensor networks. In a few decades time, computers will be inter- woven into almost every industrial product. Karl Steinbuch, German computer science pioneer, 1966 1 The vision The Internet of Things represents a vision in which the Internet extends into the real world embracing everyday objects. Physical items are no longer disconnected from the virtual world, but can be controlled remotely and can act as physical access points to Internet services. An Internet of Things makes computing truly ubiquitous – a concept initially put forward by Mark Weiser in the early 1990s [29]. This develop- ment is opening up huge opportunities for both the economy and individuals. However, it also involves risks and undoubtedly represents an immense technical and social challenge. The Internet of Things vision is grounded in the belief that the steady advances in microelectronics, communications and information technology we have witnessed in recent years will continue into the foreseeable future. In fact – due to their diminish- ing size, constantly falling price and declining energy consumption – processors, communications modules and other electronic components are being increasingly integrated into everyday objects today.
