JCIS_2015_submission_10The Internet of Things (IoT) offers a new eco-system of heterogeneous and distributed services that is available anytime and anywhere and that can be potentially accessed by any properly connected device. However, these available services are usually consumed in isolation, missing the potential that their combined usage can bring as new added-value services. In addition, the massive end-user adoption and usage of smartphones together with their powerful capabilities turn this type of devices into a promising platform to develop and execute these added-value services compositions. Moreover, end-users are nowadays getting more and more familiar with technology, fact that allows them to participate more actively in the development of new types of applications. However, this will not happen until we provide end-users with more powerful and easy-to-use tools. To this end, this paper presents an architectural solution to allow end-users building IoT services compositions by just focusing on domain-logic issues.
