A large number of middleware solutions targeted to wireless sensor networks have been deployed during the years with the aim of bridging the gap between the high level requirements of the applications and the low level hardware complexity. In the paper, a review of state-of-the-art middleware platforms is first presented by highlighting basic design(More)
The extensive diffusion of new generation wireless sensor networks requires the adoption of flexible mechanisms capable of abstracting the functionality of the nodes, facilitating their integration in larger computing infrastructures. This paper presents PyoT, a framework designed to simplify the development of complex applications for the Internet of(More)
HTTP is a widely used protocol for Web transactions and it is oriented to virtual resource management through URL mapping. The concept of resource in HTTP perfectly matches event notion in embedded devices, but HTTP can exhaust memory and processing in embedded systems. CoAP is an adaptation for resource constraint devices, it follows REST architecture and(More)
This paper describes a vehicle counter application to be used in low-cost and low-complexity devices to be deployed in next-generation pervasive Intelligent Transport Systems. The first part of the paper introduces the Linesensor theory, which exploits the temporal redundancy of the movement to enable the processing of a 1D images (i.e. lines), thus(More)
The paper proposes and discusses the integration of WSN and RFID technologies in the IoT scenario. The proposed approach is based on the REST paradigm, thanks to which the two technologies can be seamless integrated by representing sensors, actuators and RFID related data as network resources globally addressable through state-of-the-art IoT protocols. The(More)
This paper presents an innovative architecture for the instrumentation layer of a pervasive large-scale information system. State of the art examples already include an instrumentation layer in a grid infrastructure; nontheless these systems were not designed for large-scale ad-hoc networks, rapidly deployed, continuously upgraded, and dynamically(More)
The Smart Factory concept has been enabled in the last few years thanks to both Wireless Sensor Networks (WSNs) and Radio-Frequency IDentification (RFID) technologies. Although the two technologies have been adopted in isolation in factory automation applications, their partial integration start to be considered in different research fields. In this work,(More)
Video streaming applications in wireless camera networks composed by low-end devices are attractive for enabling new pervasive high value services. When complying with the 6LoWPAN standard, the reduced amount of available bandwidth imposes the transmission of low resolution images. In this paper we present a low-complexity algorithm based on background(More)
