The terahertz (THz) link provides over 100 Gb/s of data transmission rate. However, it is extremely vulnerable to obstacles and requires very narrow (highly directional) beams for highly focused energy radiation. main task THz medium access control (MAC) protocol not channel collision avoidance; instead, coordinate all the one-hop neighbors scheduled, antenna-aligned line-of-sight communications. This study aims build an intelligent MAC scheme mobile airborne networks (TANs). Our TAN design...

The medium access control (MAC) design in mobile networks with directional antennas is challenging due to the difficulty of defining exact RF interference range between two neighboring links and frequent changes node mobility. This research targets data reception (Rx) transmission (Tx) coordination issues based on computation ranges from nearby links. An innovative MAC mechanism designed three features: (1) <italic xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Many practical mobile ad hoc networks (MANET) have certain tasks instead of just randomly changing each node’s positions. We call such a mission-driven network task-adaptive MANET. A typical example is the flying (FANET) that consist unmanned aerial vehicles (UAVs), which may change its topology based on different task requirements. Each node moves to new locations targeted shape. To maintain smooth transformation and minimize position changes, during shape change, MANET typically keeps...
In this article, we propose a distributed medium access control (MAC) protocol for the unmanned aerial vehicle (UAV) network with directional antennas. It uses learning algorithm to each node's communication parameters (such as sending rate) according observations of only 1-hop neighbors. Because asynchronous and decentralized nature multi-agent deep reinforcement (MADDRL), adopt Multi Agent Deep Deterministic Policy Gradient (MADDPG) [3] generate discrete actions MAC layer protocol. Under...
Abstract Because traditional Android mobile phone passcode keypad without anti-peeping function, so we propose a kind of anti-peep code based on hybrid image and fuzzy adaptive visual distance adjustment. First, replace the key bitmaps with images to solve problem that password keyboard doesn’t have function. Then, logic principle are used user’s use problem. Finally, it is found through experiments time refresh 10 between 0.38s 0.48s, blur effect can be automatically adjusted according...
