Smart objects (SOs) have been utilized widely to transform the physical environment around us to a digital world using the Internet of things (IoT) vision. Integrating a huge number of these devices into the Internet presents a significant necessity for an efficient discovery mechanism with high capability of an autonomous configuration and detection for theses devices and their provided services...
This work proposes a data driven IoT architecture to mitigate the fragmentation and data silos in consumer IoT ecosystem. IoT data cycle is explored to understand data transformation from generation to processing, storage and dissemination. We have developed a framework called DataTweet focusing on data cycle based IoT services. The DataTweet architecture is presented along with its subsystems, services,...
Interoperability is key in any networked system. In the IoT environments, the need is further amplified by the presence of numerous heterogeneous devices. To address device and service disparity, the things will need proper addressing, registration and de-registration. This can be implemented through abstraction technologies and models such as ontologies for semantic expressiveness. The aim of this...
Adopting adequate mechanisms for security and privacy are critical to the success of Internet of Things (IoT). This paper attempts to provide secure solutions for thing authentication and access control for thing discovery. A prototype, early performance evaluation results and its deployment in a smart home is also described.
This paper describes Internet of Things (IoT) and Machine-to-Machine (M2M) communications as the enablers of smart city initiatives. The challenges in modern cities are briefly identified. Utilization of IoT based applications and services could mitigate these challenges. The paper then introduces an architecture based on oneM2M standards for smart cities. The key elements of the architecture are...
