Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Due to the increasing interest of the emerging millimeter wave (mmWave) frequency band for application to cellular networks, new flexible and scalable approaches for their modeling, analysis and optimization are needed. Recently, a new approach has been proposed: it is based on the theory of point processes and it leverages tools from stochastic geometry for tractable system-level modeling, performance...
In the recent years, multi-channel Interferometric SAR (InSAR) techniques have proved to be effective in reconstructing the Digital Elevation Model (DEM) by unwrapping the interferometric phase. Commonly, multi-baseline or multi-frequency configurations are adopted for this aim. In this paper, the possibility of jointly exploiting multi-baseline and multi-frequency approaches for SAR interferometry...
In this paper an alternative method for evaluating the spatial uniform and isotropic electromagnetic field within a reverberating chamber (RC) is proposed. Experiments accomplished at the RC of the Università degli Studi di Napoli Parthenope, formerly Istituto Universitario Navale (IUN) confirm the soundness of the proposed model and its effectiveness from an operational point of view.
This paper presents a low cost approach for structural and seismic monitoring with the aim of developing an Early Warning System. The proposed architecture is based on a customized network of multi-sensor nodes equipped with inertial sensors and a microcontroller architecture aimed to signal processing and the management of data transfer. Results presented highlight the suitability of the developed...
In the vision of the upcoming 5G communications expected to allow Internet access to different heterogeneous devices, the problem of Indoor access is under the lens of the scientific community. In order to guarantee electromagnetic safe and secure access, Visible Light Communications can be considered an enabler. In this regard trying to optimize very small cells (atto-cells) coverage is a challenging...
The paper deals with the problem of designing and implementing a measurement node based on compressive sampling (CS). The considered node is tailored for wide area sensors networks aimed to carry out measurements in frequency domain. To this aim, the node takes advantage from some known or recently proposed CS features in such a way as to outperform the nominal specification of its data acquisition...
In this paper, a 2.5D positioning system is analyzed, based on Received Signal Strength (RSS) measurements, collected from narrowband RF transmissions. The mobile node of the considered system uses multiple closely spaced receivers, collecting RSS measurements and combining them to mitigate multipath effects. Using simulations and optical approximation, the effect of antenna directivity on the positioning...
In this paper we report Radio Frequency (RF) measurements performed on a GNU Radio/Universal Software Radio Peripheral (USRP) testbed. The USRP hardware is connected to SBX daughter board, both designed by Ettus Research. We can confirm the bandwidth stated by the designer, nonetheless the output power was found to be constantly decreasing with increasing the output frequency. USRP Hardware Driver...
This paper deals with the development of a multiuser assistive system for the monitoring of elders and people with neurological pathologies (e.g. Alzheimer) during their staying in social care or health facilities. The system adopts wearable devices to monitor the dynamics of the users and a dedicated wireless network for communication. The wearable device is able to recognize critical events like...
The electrical system is facing a dramatic transformation. A main trend is the digitalization of the grid that implements automation and monitoring concepts at every voltage level. The consequent growing role of data management is calling for new paradigms in the service implementation. This paper presents a cloud-based platform concept that enables an open structure for new energy services. The architecture...
Wireless sensor networks (WSNs) are typically used to measure physical quantities of their environment at locations characterized by poor accessibility and lacking of wired infrastructure. To extend the operational time, energy harvesting systems (EHSs) support the power supply by transforming environmental energy into electrical energy. In the best case, a self-sufficient supply of the sensor node...
This paper proposes the implementation of a low-cost and reliable multipurpose wireless sensor network framework. It has been designed to be easily customizable in order to adapt it to the particular application.
Machine-to-Machine (M2M) communications have emerged as a new concept for the next generation of sensing and actuating systems. With the recent emergence of energy harvesting technologies, the current communication solutions have addressed the problem of controlling the data communication to regulate efficiently the energy consumption, aiming to avoid under and overuse of energy. However, these solutions...
In several fields of application of wireless sensors networks (WSNs) the ability of estimating the position of a node with respect to a reference coordinate is a key feature. The most of the WSN applications involve indoor environments and low costs requirements, so the Global Position System cannot always assure a reliable operating and cheap solution. As a consequence, other methods have to be considered...
Indoor localization based on inertial sensors such as accelerometer, gyroscope and magnetometer, has gathered broad interest within the scientific community. This approach in fact does not require the installation of external devices since it relies on low-cost devices of common use, like smartphones, which are used both as measurement platform and user interface. In this paper we focus the attention...
Drones like helicopters use vertical oriented rotors to lift and navigate forward. Thanks to the use of modern flight controllers, they often can fly autonomously. Namely, the user can mark target points on a map to which the helicopter is driven by the software controller without any other interventions of the user. Once on the target, the helicopter performs the intended task, such as landing, catching...
