This paper shows one solution for testing the communication through FlexRay bus, which connects multiple Electronic Control Units (ECUs) in the system. Presented implementation is specially adjusted for testing the embedded system, and it will help the assessment of reliability of the system. The focus is on detecting the errors that appear during FlexRay message transfer, messages with corrupted content and unexpected delay of the messages. Beside monitoring and data recording, it is possible to inject faults and replay the captured data. Within the paper there is also a proposed solution of a diagnostic module that collects and displays the unique error code in order to precisely determine the origin of the error that occurred. Tests were executed using VECTOR's VN Box along with supporting software.

Decode-and-forward (DF) relay system where the relay node harvests energy from the source is analyzed, for the case when time-switching relaying protocol is applied. It is assumed that both source-to-relay and relay-to-destination links experience Generalized-K fading. The outage probability of DF system is analyzed and the accurate approximation is derived in the closed-form. Numerical results that show the impact of fading and system parameters are presented and discussed.

Tactile Internet is an emerging paradigm of the next generation mobile networks (5G and beyond). Conceptually designed to respond to the most complex requirements of ultra-low latency and extremely high reliability, it was observed as capability to wirelessly control both real and virtual objects, thus requiring tactile-based control signals and audio-visual feedbacks. This vision can improve the user experience in virtual environments in the order of millisecond interaction. Future applications such as autonomous vehicles, haptic healthcare, remote robotics, and robust image processing would use the Tactile Internet and related technologies. Software-defined networking and network function virtualization, together with edge-fog computing, can be seen as new wave toward the efficient and flexible infrastructure. This work provides a comprehensive survey on recent progress and enabling technologies proposed for the Tactile Internet. By outlining the key networking solutions, together with innovative radio interface design, some open issues and future research directions to meet critical latency requirements, are highlighted, too.

In this paper, we demonstrate the influence of the line-to-spacing ratio of the Hilbert fractal antenna to its radiation characteristic. The proposed antennas realized using Hilbert fractal curves of the third order have been designed to operate at 2.45 GHz according IEEE 802.15.1 standard. Due to specific configuration of the Hilbert fractal curves and mutual coupling between fractal segments, the radiation patterns of the proposed antenna can be significantly changed by changing the line-to-spacing ratio of the Hilbert fractal radiators. The proposed antenna has been fabricated in Low Temperature Co-fired Ceramic (LTCC) technology. The measured result of the Hilbert dipole antenna confirmed its good impedance matching and return loss.

This paper examines the possibility of developing a low profile antenna with fractal design which can achieve high gain for RFID applications in the frequency range from 865 to 868MHz. The advantages of the suggested structure are high gain, small physical dimensions and low profile compared to traditional antennas. The proposed approach is applicable to EMI/EMC sensors and probes as well.

In this keynote invited paper, to address key challenges for beyond 5G wireless technologies in a simultaneous manner, we propose an orbital angular momentum (OAM) based, energy-efficient multidimensional coded modulation. The key idea is to employ all available degrees of freedom (DOFs) to convey the information over the wireless links including amplitude, phase, polarization state, and spatial-domain DOFs. In particular, the OAM is associated with azimuthal phase dependence of the wavefront, and represents an underutilized DOF. Given that OAM eigenstates are orthogonal, an arbitrary number of bits per symbol can be transmitted. To implement OAM multiplexer and demultiplexer in the RF domain, we propose to use a properly designed antenna arrays. Monte Carlo simulations demonstrate high tolerance to fading effects of LDPC-coded multidimensional signaling schemes compared to conventional LDPC-coded QAM.

Unified software architecture of the proposed solution is designed to be easily ported on different hardware and easily integrated in different environments. The main goal of such implementation is to create an optimized DTV software stack with low memory footprint and highly portable hardware abstraction layer, while retaining solid performance, usability and compliance to the required digital and analog broadcasting standards.

In this paper we present a novel architecture for enabling on-line communication with marine environment monitoring deployments. We rely on a set of communication technologies that range from IoT related low data rate communication standards to the widely adopted Wi-Fi and LTE protocols that are able to support bandwidth demanding applications. To achieve energy-efficient results we turn off all the power-hungry interfaces and peripherals, while maintaining a low-power interface active, dedicated to control the rest of the components. Finally, we present the installation of the developed system in the Vida oceanographic buoy, in Slovenia and evaluate our device in terms of power consumption.

Intelligent radio resource distribution techniques play an important role in improving the overall performance of next-generation networks. An efficient scheduling algorithm can help to achieve higher data rates, lower latency and increased fairness for users. This paper evaluates the performance of an indoor network, simulated using the Realistic Indoor Environment Generator (RIEG), when 11 different Throughput Averaging Methods (TAMs) for the Proportional Fair (PF) algorithm are used. The TAMs are compared by using a Comparative Factor (CF) that simultaneously takes into account the average throughput of the indoors users, the fairness and the outage ratio. Simulation results show that when improvement in fairness is the main goal, the recently-proposed low-complexity Median Method (MM) and Quartile Mean Method (QMM) are major rivals to the widely-used Arithmetic Mean Method (AMM) and Original Mean Method (OMM), while the Modified Quartile Mean Method (MQMM) is the leader when the average throughput of indoor users is the most important factor.
