Carrier-Mediated Transport01:06

Carrier-Mediated Transport

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...

We developed a reliable asynchronous image transfer protocol (RAIT) using a double sliding window method to prevent packet loss during node-to-node transfers. RAIT significantly enhances image transmission reliability over existing protocols.

Area of Science:

  • Computer Science
  • Network Engineering
  • Data Transmission

Background:

  • Existing image transfer protocols face challenges with packet loss due to communication failures and network congestion.
  • Node-to-node data transfer requires robust mechanisms to ensure reliability.

Purpose of the Study:

  • To propose a novel reliable asynchronous image transfer protocol (RAIT).
  • To enhance the reliability of image transmission in networked systems.

Main Methods:

  • Implementation of a double sliding window method for both receiving and sending queues.
  • Utilizing a cross-layer design integrating RAIT, routing, and queue layers.
  • Employing preemptive scheduling of packets by the routing node.
