The Internet of Things (IoT) promises major technology development that will transform 'vertical' industrial productivity, innovation and new business opportunities. 'IoT' offers a significant and transformational economic benefit through smarter use of infrastructure, smart cities and intelligent asset management. With the IoT it can be possible to manage and control temperatures, ventilation, lighting, access, parking, room occupancy, elevators and energy usage in a facility, either on-site or remotely. IoT makes possible a variety of applications using connected devices and data driven decision support systems. In order to make the IoT pervade people's everyday life, the security of the IoT must be strengthened. As more devices become connected to the Internet, networks between devices, especially sensors, will become more prominent. IoT has the potential

for unlocking Trillions of dollars of value – through structural improvements in operational efficiencies in every industry sector. Early stage IoT initiatives in Smart Energy, Smart Retail, and Cyber Security are the basis for our conviction on a longtail positive impact to select players in our universe. But significant work lies ahead to make the promise a reality

The impact of IoT in the commercial sector results in significant improvements in efficiency, productivity, profitability, decision-making and effectiveness. IoT is transforming how products and services are developed and distributed, and how infrastructures are managed and maintained. It is also redefining the interaction between people and machines. There are several applications where prediction techniques are applied on the contextual data generated by IoT to make the user more comfortable and system-friendly. The Book on 'Applications of Internet of Thing (IoT) in Digital Era' covers a wide-ranging and interesting topics encompassing: Smart city, Smart building, Cyber security, Defense security, Manufacturing industries, Intelligent transport system, Healthcare, Tourism and Hospitality, Weather forecasting, E. Banking, Retail banking and financial services, Logistics and Supply chain management.
