As the ideas and technologies behind the Internet of Things (IoT) take root, a vast array of new possibilities and applications is emerging with the significantly increased number of devices connected to the Internet. Moreover, we are also witnessing the fast emergence of location-based services with an abundant number of localization technologies and solutions with varying capabilities and limitations. We believe that, at this moment in time, the successful integration of these two diverse technologies is mutually beneficial and even essential for both fields. IoT is one of the major fields that can benefit from localization services, and so, the integration of localization systems in the IoT ecosystem would enable numerous new IoT applications. Further, the use of standardized IoT architectures, interaction and information models will permit multiple localization systems to communicate and interoperate with each other in order to obtain better context information and resolve positioning errors or conflicts. Therefore, in this work, we investigate the semantic interoperation and integration of positioning systems in order to obtain the full potential of the localization ecosystem in the context of IoT. Additionally, we also validate the proposed design by means of an industrial case study, which targets fully-automated warehouses utilizing location-aware and interconnected IoT products and systems.

Despite the significant potential of the Internet of Multimedia Things (IoMT), the integration of multimedia services and devices into the Internet of Things (IoT) still stays a challenge due to the limited capabilities of IoT devices and distinct characteristics of multimedia applications. In this paper, we investigate a novel, efficient and light-weight streaming protocol for IoMT to enable numerous multimedia-based IoT applications and services. Further, the use of standardized IoT architectures, interaction and information models will provide syntactic, structural and semantic interoperability for IoMT which will permit heterogeneous multimedia things to communicate and interact with each other and with other connected things seamlessly. Additionally, we also validate the proposed design by means of a real-life use case and implementation, which targets the ability of end-to-end bidirectional voice communication over NB-IoT technology, a long-range limited bit rate communication technology. Also, we assess the suitability of NB-IoT for handling less-demanding IoT multimedia applications by means of theoretical calculations and practical experiments. [ABSTRACT FROM AUTHOR]
