Abstract
The Internet of Things (IoT) offers an incredible innovation potential for developing smarter applications and services. However, today we see solutions in the development of vertical applications and services reflecting what used to be the early days of the Web, leading to fragmentation and intra-nets of Things. To achieve an open IoT ecosystem of systems and platforms, several key enablers are needed for effective, adaptive and scalable mechanisms for exploring and discovering IoT resources and their data/capabilities. This paper discusses our work in the EU H2020 IoTCrawler project. Its focus is on the integration and interoperability across different platforms, through dynamic and reconfigurable solutions for discovery and integration of data and services from legacy and new systems. This is complemented with adaptive, privacy-aware and secure solutions for crawling, indexing and searching in distributed IoT systems. IoTCrawler targets IoT development and demonstrations with a focus on Industry 4.0, Social IoT, Smart City and Smart Energy use cases.
