5G and B5G systems will be designed to better utilize the scarce spectrum. This improvement will be realized through enhanced allocation and management schemes, as well the added viability of utilizing unlicensed spectrum. Meanwhile, 5G/ B5G emphasize an ever more personalized communication experience through adapting network and spectrum choice to user requirements and experience. QoE thus becomes a critical basis for resource allocation in future networks. However, current QoE approaches are l...

This paper investigates the performance of spatial modulation for multiple-input multiple-output underlay spectrum-sharing systems in the presence of three practical deleterious effects: 1) transceiver hardware impairments, 2) outdated channel state information (CSI), and 3) imperfect CSI. In particular, for Rayleigh fading channels, a closed-form expression of the average pairwise error probability and a tight upper bound of the average bit error rate (ABER) are derived. In addition, asymptotic...

The aim of this study is to characterise the artificial normal skin and melanoma by testing samples with different fibroblast and metastatic melanoma cell densities using terahertz (THz) time-domain spectroscopy (TDS) attenuated total reflection (ATR) technique. Results show that melanoma samples have higher refractive index and absorption coefficient than artificial normal skin with the same fibroblast density in the frequency range between 0.4 and 1.6 THz, and this contrast increases with freq...

The skin dehydration level can be used to infer serious health conditions in patients since diseases like cardiovascular abnormality, diabetes and cancer symptoms do exhibit correlation with skin disorders. Therefore a systematic analysis of human skin hydration levels is critical for multiple health care applications. Motivated by this, in this study we proposed a unique approach of measuring body hydration levels against different body postures using skin conductance electrical activity. In th...

Future wireless communication systems, including fifth-generation (5G) networks and the Internet of Things (IoT), require a massive number of inexpensive transceivers. These transceivers come with various hardware impairments, such as phase noise and in-phase/quadrature phase ( I/Q) imbalance. This piece of work studies the performance of underlay cognitive radio (CR) networks, considering the joint effect of I/Qimbalance and imperfect channel-state information (CSI) at the secondary user....

Driving behavior profiling has important relevance in many driving applications. For instance, car insurance companies have been recently applying a new insurance paradigm in which a driver's insurance premium is adapted based on realtime driving behavior. Driver profiling process is composed of two sub processes. The first is the detection of certain driving behaviors by acquiring data from onboard devices such as smartphones and OBDII units, whereas the second is the scoring process in which t...

Revolutionary advancement in realizing nanosensors promises unprecedented enhancement of applications in several fields such as health, industry, agriculture, environment, sport, etc. The small size of nano-sensors and their THz band leads to significant constraints in energy, memory, processing, and transmission range. To combat these constraints, recent progress and active research in nano-sensing technology have led to increasing interest in connecting these nano-sensors in a new network tech...
The steadfast emergence of AVs promises many advantages, including an enhanced driving and transportation experience for humans, and increased automation of the production and distribution cycles for businesses. Meanwhile, route planning tools have evolved greatly over recent years and have grown popular across the different sectors. Despite this evolution, we argue in this work that current route planning approaches are not readily applicable to AVs and their emerging requirements. A smooth and...
