Proposal of a Semantic Vocabulary for Discovering Services in IoT

The Internet of Things is a technological revolution that connects electronic devices such as home appliances or means of transportation to the Internet, based on communication protocols, domains and applications connecting physical objects such as sensors or remote devices through wireless communications. For intelligent objects to perform their functions when connected to the Internet using the resources of the web, it is necessary that the communications interfaces can handle the search of a certain service requested by the user with precision. The search for this service occurs with a clear and objective semantics used in the vocabulary for the request process. In some researches cited in the work the use of semantic vocabularies in web services, presents some problems that persist in the clear detection of these services. These works that perform service search were analyzed and correlated their positive and negative points about the semantics used in the vocabulary and its application in IoT. Thus, to obtain a service discovery process, this work presents a semantic vocabulary that performs service discovery in IoT.
