RUDN University mathematicians simulated the work of a cellular network. In their model unmanned aerial vehicles are employed as additional transmitters. Most of the available communication systems give a flat coverage and do not take into account the difference in altitude, which results in the appearance of the so-called 'blind' zones. Flying drones will help in solving this issue. The work is published in the journal IEEE Transactions on Vehicular Technology.

Researchers find AI-generated reviews and comments pose a significant threat to consumers, but machine learning can help detect the fakes.

Hateful text and comments are an ever-increasing problem in online environments, yet addressing the rampant issue relies on being able to identify toxic content. A new study by the Aalto University Secure Systems research group has discovered weaknesses in many machine learning detectors currently used to recognize and keep hate speech at bay.

A team of researchers from the U.S. Army Research Laboratory, the University of Canterbury in New Zealand and the Gwangju Institute of Science and Technology in the Republic of Korea have taken a step toward the development of moving target defense techniques in software-defined networks. This is a demanding cybersecurity research topic, scientists said.

There are many barriers to innovation in wireless communications. Inadequate documentation; uncooperative chipset manufacturers; widely varying hardware and software specifications; steep learning curves in the experimentation phase and difficulties in prototyping are among the biggest issues that hamper development.
