Reinforcement01:23

Reinforcement

Positive and negative reinforcement are key concepts in operant conditioning, a learning process where the consequences of a behavior affect the likelihood of that behavior being repeated.
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:
Cognitive Learning01:21

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
Observational Learning01:12

Observational Learning

Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning because...
Avoidance Learning and Learned Helplessness01:14

Avoidance Learning and Learned Helplessness

Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
Energy to Drive Translocation01:37

Energy to Drive Translocation

Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.
Generally, polypeptides are unfolded by two distinct...
Ampere-Maxwell's Law: Problem-Solving01:17

Ampere-Maxwell's Law: Problem-Solving

A parallel-plate capacitor with capacitance C, whose plates have area A and separation distance d, is connected to a resistor R and a battery of voltage V. The current starts to flow at t = 0. What is the displacement current between the capacitor plates at time t? From the properties of the capacitor, what is the corresponding real current?
To solve the problem, we can use the equations from the analysis of an RC circuit and Maxwell's version of Ampère's law.
For the first part of the problem,...

Area of Science:

  • Telecommunications Engineering
  • Wireless Communication Systems
  • Artificial Intelligence in Networking

Background:

  • Terrestrial Networks (TNs) face challenges in providing connectivity to remote areas due to high deployment costs and sparse user density.
  • Non-Terrestrial Networks (NTNs), particularly High-Altitude Platform Stations (HAPS), offer a solution for bridging the digital divide by providing broader coverage and lower latency than satellites.
  • Battery-powered Internet of Things (IoT) devices on HAPS-enabled networks require efficient power management to balance data throughput, battery longevity, and packet delays.

Purpose of the Study:

  • To develop and evaluate an energy-efficient power control framework for IoT devices operating with High-Altitude Platform Stations (HAPS) in 6G Non-Terrestrial Network (NTN) ecosystems.
  • To address the critical challenge of maximizing energy efficiency (EE) for battery-powered IoT devices while maintaining high data throughput and minimizing queuing delays.
  • To compare the performance of a novel Q-learning based Reinforcement Learning (RL) approach against traditional heuristic algorithms for power management.

Main Methods:

  • A Q-learning based Reinforcement Learning (RL) framework was proposed to dynamically manage the transmit power of IoT devices.
  • The RL agent observes the device's battery level and queue state to select optimal power levels across time slots.
  • The proposed method was simulated and compared against benchmark schemes including Round Robin (RR), Max-SNR, and fixed-power allocation.

Main Results:

  • The Q-learning framework achieved up to 40% higher average energy efficiency (EE) compared to benchmark schemes.
  • The proposed method demonstrated consistently lower power consumption and superior statistical reliability in EE.
  • The Cumulative Distribution Function (CDF) of EE was significantly improved, indicating enhanced performance.

Conclusions:

  • Q-learning is a highly effective and adaptive approach for energy-aware power control in next-generation HAPS-assisted IoT deployments.
  • The proposed RL framework offers a scalable solution for optimizing power management in 6G NTN environments.
  • This research highlights the potential of AI-driven techniques to overcome key challenges in future wireless communication systems.
