Lecture 7: Internet of Things By D. Najla Al-Nabhan 1 Internet of Things 2 Lecture Aims
The main aim of this lecture is to introduce the fundamental concepts of the Internet of Things and its applications and architecture models; Introduction to the technologies and mechanisms for sensing, actuation, processing and cyber-physical data communication. Discussing semantic technologies, service oriented solutions and networking technologies that enable the integration of Internet of Things data and services into the
cyber world (i.e. the Internet and the Web). To develop practical skills that can be transferred into a real-world environment. 3 4

12 12 What does Internet of Things (IoT) mean? Extending the current Internet and providing connection, communication, and internetworking between devices and physical objects, or "Things," is a growing trend that is often referred to as the Internet of Things.
The technologies and solutions that enable integration of real world data and services into the current information networking technologies are often described under the umbrella term of the Internet of Things (IoT) 13 Internet of Things Module

Market growth According to a study conducted by Frost & Sullivan in 2011, the global RFID market of $3 billion to $4 billion (in 2009) will grow by twelve percent per year through 2016 and reach a volume of approximately $6.5 billion to almost $9 billion. 80 percent of all households in the European Union are expected to have intelligent power meters by 2020.
A buildings energy management can then be monitored and administered remotely via a smartphone or a PC. Market experts predict that this global market, which represented $5.3 billion in 2010. In February 2012 the Chinese government therefore decided to set up a fund of approximately $775 million to support this field in the
next five years. It will grow to $11 billion by 2015. This sector is expected to grow to $116 billion by 2015, according to a report published by the Xinhua News Agency in late 2010. 18 Source: Siemens, http://www.siemens.com/innovation/apps/pof_microsite/_pof-fall-2012/_html_en/facts-and-forecasts-growth-market-of-the-future.html Smart product sales 19
