—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.

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)
The increasing interest about the Internet of Things (IoT) is almost as remarkable than its practical absence in our everyday lives. Announced as the new breakthrough in IT industry, the domain is characterized by a large number of architecture propositions that are in charge of providing a structure for applications creation. These architectures are needed(More)
Since the Internet of Things (IoT) has become more and more important, new solutions should be proposed in order to adapt the specificities introduced by this interconnection of the physical world (Sensors and Actuators) and the public networks (The Internet). Some of these solutions use a Cloud approach. The amount of data collected by Things rises the(More)
