Context information sharing for the Internet of Things: A survey
Description
Internet of Things (IoT) technology is starting to make an impact in a wide array of applications, including smart cities and industrial environments. Such real-world applications combine computation, communication, sensing, and in some cases, actuation, to monitor and remotely control the environment. Data is at the core of such real-world IoT applications. Analysis, modeling, and reasoning of data are necessary to gain valuable insights. Application developers employ context-aware systems to translate the data into contextual information, which then allows the applications to act cognitively. Context sharing platforms offer a solution to distribute context information to those who may be interested in it, thus enabling context interoperability among different entities. This survey first examines the requirements for sharing context information. It then reviews the relevant literature for context sharing and classifies them based on their requirements and characteristics. Challenges and future directions are presented to encourage the development of context sharing platforms.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.

| Additional Information: | Funding Information: One of the Horizon 2020 goals is making data interoperable allowing exchange and re-use between researchers, institutions, organizations, countries, etc. FIESTA-IoT 12 12 is an example of a project from Horizon 2020 that primes for interoperability. FIESTA-IoT is an infrastructure to provide data interoperability among already deployed IoT systems, platforms, and testbeds. It uses a common ontology to guarantee semantic conformity among different providers. It also provides a standard API for communication giving access to the information by the IoT systems connected to it. INTER-IoT and INTER-Health are also projects that received funding from Horizon 2020. The INTER-IoT 13 13 project goal is to provide interoperability on heterogeneous IoT platforms. INTER-IoT encompasses other projects to reach the interoperability in different layers: device level, networking level, middleware level, application service level, data and semantics level, integrated IoT platform level, and at the business level. On the data and semantics level, INTER-IoT developed the Generic Ontology for IoT Platforms (GOIoTP 14 14 ) to support the semantic matching in IoT scenarios, facilitating the context sharing process. INTER-Health is a specific project under the INTER-IoT umbrella that presents an application scenario with context sharing [66] . On INTER-Health, messages and entities are described semantically using domain ontologies, facilitating the interoperability. It also has a specific communication bus for sharing context information to the subscribers.
