—Wireless Sensor and Actuator Networks (WSAN) and permanent connections to the Internet converge to be an emerging and promising field: Machine-To-Machine (M2M) services. To take advantages of this new field, hardware and software infrastructure compliance must be verified. Services expected by M2M alter the organization of WSAN. The software design in this(More)
In this paper, we propose a comparative study between results generated by a real 802.11 testbed in different outdoor and indoor environments and 3 usual network simulators (NS2, QualNet and OPNET). The goal of this study is to evaluate the relevance of the low layers recently implemented in these simulators. The motivation of this paper is to provide a(More)
HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt età la diffusion(More)
Smart phones, PDA, Sensors, Actuators, Phidgets and Smart Objects (i.e. objects with processing and networking capabilities) are more and more present in everyday's life. Merging all these technologies with the Internet is often described as 'Internet of Things' (IoT). In the IoT vision, Things around us provide a pervasive network of interacting and(More)
Facilitating the creation of Internet of Things (IoT) applications is a major concern to increase its development. D-LITe, our previous work, is a framework for that purpose. In D-LITe, Objects are considered as part of a whole application. They offer a REST web service that describes Object capabilities, receives the logic to be executed, and interacts(More)
Emergency management is a highly critical domain where the information transmission in real-time to the appropriate stakeholders is essential. Based on the results of the “Web of Objects” ITEA 2 project, this paper presents an IoT-based devices collaboration solution across an emergency management workflow, where the exchanged messages are(More)
With the emergence of IoT devices, such as smartphones, temperature and light devices, etc., the ways of creating IoT applications has changed. IoT applications are often created and managed by a set of central points (orchestration) for different users. However, users may desire to create and manage their own applications based on their own logic in a(More)
In this work, we present a complete architecture for designing Internet of Things applications. While a main issue in this domain is the heterogeneity of Objects hardware, networks and protocols, we propose D-LITe, a solution to hide this wide range of low layer technologies. By abstracting the hardware, we focus on object's features and not on its real(More)
