The availability of energy-efficient wireless proto-cols and architectures is a mandatory requirement for the development of wearable measurement instruments suitable for continuous monitoring of medical parameters. In this context, we propose EEG-over-BLE, a novel architecture for multi-channel electroencephalogram (EEG) monitoring systems. Basically, the proposed architecture combines Bluetooth technology with a near-lossless EEG compression algorithm and a simple channel encoding scheme in order to largely reduce power consumption. Here we present the results of a detailed simulation campaign aimed at assessing the performance of the proposed architecture in terms of energy consumption, packet loss rate and end-to-end latency. According to simulation results, when EEG-over- BLE sensor nodes are powered with commercial small form factor batteries, their lifetime is over 66 days. At the same time, a packet loss rate lower than 0.1 % and a latency below 40 ms are achieved.

Today, cyber security is a very critical issue to be addressed at several levels for minimizing the effects and consequences of cyber attacks. In the last decade many coun-termeasures and intrusion detection systems (IDSs) have been developed for facing this important issue, and to keep always high the level of security, all systems (both hardware and software features) should be continuously updated.

The technologies of cellular networks have considerably evolved over the last few decades, becoming almost ubiquitous in population life. One of the main characteristics of those technologies is their foundation on electromagnetic field (EMF). Consequently, there is an expectation of even greater increase of human exposure due to multiple EMFs, generated by such technologies and their perspective evolutions, for instance, the fifth generation of mobile telephony-5G. Thus, the EMF monitoring process and the suitable assessment of human exposure to EMFs is an important topic for relevant research community, as well as for a number of public debates on dangerous health effects of EMF exposure. In this paper, an overview of the Serbian EMF RATEL network and its approach of continuous EMF monitoring will be presented, focusing on two case studies where base station (BS) acts as a dominant EMF source in the environment.

With the increasing amount of LED lighting infrastructure present in our homes, offices, and vehicles, camera Communication (CamCom) protocols gained special interest in networking. Here the transmitters are the blinking LEDs, with blinking frequency high enough to not be visible for human eyes, and the receivers are commercial cameras with much lower sampling rate, thus undersampling necessarily happens. In applications, where the transmitted information is short and repeated periodically (e.g. beaconing in indoor localization systems), a natural way of message transmission is based on the equivalent sampling phenomenon. This paper investigates the effect of design parameters on the possible bitrate of the transmission in the practically important case when the transmitter and the receiver are unsynchronized and their clocks may drift. A design method will also be presented, which allows the optimal choice of parameters.

In this paper, we analyze the Brillouin scattering properties of optical fiber tapers drawn from Ge-doped and F-doped silica fibers. Finite-element-method (FEM) simulations have been carried out to determine the optical and acoustic waveguiding properties of the tapered fibers, and the corresponding acousto-optic overlap integrals. The numerical results are compared to experimental measurements of the Brillouin gain spectrum (BGS), carried out using a Brillouin optical frequency-domain analysis (BOFDA) configuration operating at 1550 nm wavelength and featuring a spatial resolution as low as 5 mm. The fabricated sensors are promising platforms for quasi-distributed refractive index measurements.

This paper presents a low-power Visible Light Localisation (VLL) Artificial Intelligence (AI)-enabled system for Indoor Positioning (IP) purposes. Compared to other IP techniques, VLL offers a similar positioning accuracy, but with the extremely desirable feature of low energy consumption, an aspect of primary relevance in the framework of Wireless Sensor Networks (WSN), self-sufficient sensing systems, Industry 4.0 and Internet of Things (IoT). The proposed system is composed of three modulated optical sources (i.e. LEDs) and a photodiode receiver mounted on the target to be localised. The localisation task is performed by processing the received light intensities through Machine Learning (ML) regression models trained with a set of data gathered during a calibration phase. The regressors are designed to be executed on a low-power microcontroller present in the target, hence establishing an embedded ML paradigm also preserving reduced power consumption features. The proposed models are trained exploiting datasets with different sizes, searching for a trade-off between the training set size, i.e. the duration and complexity of the calibration phase, and the maximum tolerable root mean square error (RMSE). In both cases, some localisation tests show that a satisfactory accuracy can be reached even with a limited complexity of the calibration procedure and that the obtained results fulfil the error constraint used for model design.

In the context of smart cities, connecting devices in the urban environmet present not few difficulties in terms of obstacles to propagation. On top of already defined and certified protocols, such as wM-Bus, which still holds its position and usability, new services are developed for the energy-saving purpose of giving the citizen new comforts and new interactions with the urban environment. In this article, an overlay protocol to a wM-Bus wireless network for smart lighting is presented. The proposed method uses the existing wM-Bus network layer to reach high distances and mesh operation to overcome the topological difficulties introduced by the city obstacles. The protocol description, simulation and experimentation phases are presented.

Soft continuum robots are a new class of robotic devices, which are very promising for enabling measurement applications especially in remote, difficult-to-reach environments. In this work, we propose the use of a particular soft robot, which is able to evert and steer from the tip, as a sensor delivery system. The measurement system consists of two major sections: i) the robotic platform for movement purposes; and ii) the sensing part (i.e., a sensor attached to its tip to enable the measurement). As a case study of the use of the soft-growing robot as a sensor-delivery system, the transportation of a wired thermocouple towards a remote hot source was considered. The preliminary results anticipate the suitability of soft continuum robotic platforms for remote applications in confined and constrained environments.

LoRa (Long Range) technology, with great success in providing coverage for massive Internet-of-things (IoT) deployments, is recently being considered to complement the terrestrial networks with Low Earth Orbit (LEO) satellite connectivity. The objective is to extend coverage to remote areas for various verticals, such as logistics, asset tracking, transportation, utilities, agriculture, and maritime. However, only limited studies have realistically evaluated the effects of ground-to-satellite links due to the high cost of traditional tools and methods to emulate the radio channel. In this paper, compared to an expensive channel emulator, we propose and develop an alternative method for the experimental study of LoRa satellite links using lower-cost software defined radio (SDR). Since the working details of LoRa modulation are limited to the reverse-engineered imitations, we employ such a version on SDR platform and add easily controllable adverse channel effects to evaluate LoRa for satellite connectivity. In our work, the emulation of the Doppler effect is considered as a key aspect for testing the reliability of LoRa satellite links. Therefore, after demonstrating the correctness of the (ideal) $L$ oRa transceiver implementation, achieving a low packet error ratio (PER) with a commercial $L$ oRa receiver, the baseband signal is distorted to emulate the Doppler effect, mimicking a real LoRa satellite communication. The Doppler effect is related to time-on-air (ToA), bounded to communication parameters and orbit height. Higher ToAs and lower orbits decrease the link duration, mainly because of dynamic Doppler effect.

In this work, a novel sensing approach used to develop a micro-liquid volume measurement system is exploited. This sensing methodology exploits the effects induced by a small liquid volume in contact with a patch of a plastic light-diffusing fiber (LDF) connected at the input of a surface plasmon resonance (SPR) sensor realized in a D-shaped plastic optical fiber (POF). More in detail, with a fixed solution present on the SPR-POF sensor, when a different micro-liquid volume is in contact with the LDF patch, the mode profile of the light into the patch and, so, in the SPR-POF sensor changes, producing a shift of the SPR spectra. As a proof of concept, the described sensor system has been tested in a volume range from $0 mu mathrm{l}$ to 5 μl with a step size of 1 $mumathrm{l}$. The obtained results have highlighted a good linear response with a sensitivity and a resolution equal to about 0.337 $text{nm}/mumathrm{l}$ and 0.59 $mu mathrm{l}$, respectively.
