Internet of Things (IoT)
− Extending the current Internet and providing connection, communication, and inter-networking 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)”

Challenges and opportunities
− Providing infrastructure − Publishing, sharing, and access solutions on a global scale− Heterogeneity and interoperability at different layers− Indexing, query and discovery (data and resources)− Aggregation, integration and fusion− Trust, privacy and security− Data analytics and creating actionable knowledge
− Integration into services and applications in e-health, the public sector, retail, manufacturing and personalised apps.− Mobile apps, location-based services, monitoring control etc.
− New business models
