Summary
Round Robin based Intermittent Periodic Transmit (RR-IPT) enhances multi-hop wireless backhaul networks. This study compares RR-IPT with CSMA/CA, finding RR-IPT superior for packet loss, while CSMA/CA excels in throughput and delay.
Area of Science:
- Wireless communication networks
- Network performance optimization
- Telecommunications engineering
Background:
- Multi-hop wireless backhaul networks (MWBN) require efficient relaying strategies.
- 2-dimensional deployment of relay nodes presents unique scheduling challenges.
- Intermittent Periodic Transmit (IPT) offers a potential solution for efficient relaying.
Purpose of the Study:
- To investigate a multi-channel packet scheduling and forwarding scheme for Round Robin based Intermittent Periodic Transmit (RR-IPT).
- To compare the performance of RR-IPT with carrier sense multiple access with collision avoidance (CSMA/CA) in MWBN.
Main Methods:
- Developed a multi-channel packet scheduling and forwarding scheme for RR-IPT.
- Utilized one channel for downlink traffic forwarding via RR-IPT.
- Allocated the other channel for uplink traffic and a portion of downlink traffic.
- Compared RR-IPT with CSMA/CA for uplink/downlink packet forwarding.
Main Results:
- RR-IPT demonstrated higher efficiency in reducing packet loss rate.
- CSMA/CA showed better performance in terms of system throughput.
- CSMA/CA provided improvements in packet delay.
Conclusions:
- RR-IPT is more effective for minimizing packet loss in MWBN.
- CSMA/CA offers advantages in maximizing system throughput and reducing packet delay.
- The choice between RR-IPT and CSMA/CA depends on specific network performance priorities.

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.

Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

17.8K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

01:22Carrier Generation and Recombination
1.3K
Carrier generation is the process by which electron-hole pairs (EHPs) are created within the semiconductor. In direct-bandgap semiconductors, such as gallium arsenide (GaAs), this occurs efficiently when energy absorption prompts valence electrons to leap into the conduction band, leaving behind holes.
This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
Indirect generation involves an...

1.3K
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...
