A general modeling framework for realistic performance evaluations of tactical mobile ad-hoc networks deployed in mountainous areas is presented. The framework is easily extensible, and can be eventually automated. It can be also used to generate data for other network simulators. The framework utilizes the freely downloadable high resolution 3D terrain data to define time dependent trajectories of network nodes. The node speeds and directions are linked to the terrain profile which extends the previously proposed mobility models. The path-loss analysis along the node trajectories revealed the need for aerial relays to enable full network connectivity at all times. The network consisting of 5 cluster heads and a single stationary relay is considered as a case study. The relay location and its antenna height are optimized to achieve the line-of-sight connectivity over the whole mission duration. The antenna radiation pattern at the relay is incorporated in the analysis. The resulting star network topology is used by the cluster heads to broadcast their packets to all other cluster heads. Several relaying schemes including the amplify-and-forward and the decode-and-forward relaying are studied together with the go-back-N retransmissions to achieve the reliable data transfer.

“…To start off the methodology, one must first determine what criteria should be used to evaluate the methods being used. In this instance, since this research is heavily based on qualitative research methods and relies on interviews as its main source of data, then the criteria to evaluate the method would be [16,71,72,73,74]:…”

This research is set to answer the question how Metaverse can be a dangerous space for its users. Metaverse is a collection of Meta applications such as Facebook, Instagram, WhatsApp and Oculus that is integrated into virtual reality (VR) and augmented reality (AR). To answer the question, different issues that were undertaken in the history of Meta and its CEO, Mark Zuckerberg, was taken into account to see the potential negative effects it will have on end-users. The potential issues Metaverse can have includes issues with uneven power distribution, issues with cyber security and privacy threats, and negative impact on the user’s mental health. An interview was conducted and the results supported the prior claims, with an emphasis on the dangers of lack of security and privacy leaks and breaches, followed by mental health concerns, then lack of regulations, followed by spread of misinformation and abuse of power. The solutions to these issues consisted of adding and adopting better regulations, integrating a monitoring system, and including a function for tracking and limiting end-user’s screentime. Alas, technology and the internet are ever-changing and needs constant evaluation and regulations, especially if it is from a big tech-company such as Meta. A company is useless without its customers, so keeping them safe should always be a top priority.
