In this paper, cooperative simultaneous wireless information and power transfer terahertz (THz)-nonorthogonal multiple access (NOMA) is considered to overcome the challenging shortages that THz communications have due characteristics. The proposed system presents a noticeable improvement in energy efficiency (EE) spectral (SE), addition other important metrics. By utilizing NOMA technology freq...

The commercial fifth-generation (5G) wireless communications networks have already been deployed with the aim of providing high data rates. However, rapid growth in number smart devices and emergence Internet Everything (IoE) applications, which require an ultra-reliable low-latency communication, will result a substantial burden on 5G networks. As such, rate that could be supplied by unlikely ...

Each generation of cellular communication systems is marked by a defining disruptive technology its time, such as OFDM for 4G or Massive MIMO 5G. Since AI the our it natural to ask what role could play 6G. While clear that 6G must cater needs large distributed learning systems, less certain if will in design itself. The goal this article paint vision new air interface partially designed enable ...

As of today, the fifth generation (5G) mobile communication system has been rolled out in many countries and number 5G subscribers already reaches a very large scale. It is time for academia industry to shift their attention towards next generation. At this crossroad, an overview current state art vision future communications are definitely interest. This article thus aims provide comprehensive...

We report on the experimental demonstration of considerable lowering of stimulated luminescence (lasing) threshold in R6G laser dye solution doped with metal agglomerates (Ag, Al, Ni) upon second harmonic of Nd:YAG-laser illumination. Due to strong structural coupling between individual nanoparticles, they may form fractal agglomerates providing an extreme optical pump-field enhancement near th...

Although the fifth generation (5G) wireless networks are yet to be fully investigated, visionaries of 6th (6G) echo systems have already come into discussion. Therefore, in order consolidate and solidify security privacy 6G networks, we survey how may impact envisioned systems, possible challenges with different technologies, potential solutions. We provide our vision on key performance indicat...

Terahertz communication has been proposed as one of the basic key technologies sixth-generation wireless network (6G) due to its significant advantages, such ultra-large bandwidth, ultra-high transmission rates, high-precision positioning, and high-resolution perception. In terahertz-enabled 6G systems, intelligent reconfiguration propagation environments by deploying reconfigurable surfaces (R...

Security is one of the most important aspects any network, but it also overlooked aspects. In wireless networks, main design focus usually data rate, with security being more an afterthought than a requirement. era when much society spends significant amount time online, poor can expose sensitive personal information, ranging from individual preferences to bank account details.
