Area of Science:

  • Engineering
  • Computer Science
  • Oceanography

Background:

  • Underwater acoustic sensor networks (UASN) face significant challenges due to the slow speed of acoustic waves, leading to greater propagation delays compared to terrestrial networks.
  • These delays complicate communication and cause collisions, while existing waiting mechanisms reduce bandwidth utilization and overall throughput.
  • Efficient data transmission and resource management are critical for the functionality and longevity of UASNs.

Purpose of the Study:

  • To propose a novel slotted medium access control (MAC) protocol designed to enhance bandwidth utilization in underwater acoustic sensor networks (UASN).
  • To address the issues of long propagation delays and low bandwidth utilization in UASNs.
  • To improve overall network performance, including throughput and energy consumption.

  • Reduction of wait times for data transmission to improve network efficiency.

Main Results:

  • The proposed protocol demonstrates enhanced bandwidth utilization by effectively managing temporal and spatial resources.
  • Performance evaluation indicates reduced energy consumption compared to existing protocols, particularly with large data packets or dense sensor deployment.
  • The study shows higher throughput in the proposed protocol under various network conditions.

Conclusions:

  • The developed slotted MAC protocol offers a viable solution for improving efficiency in underwater acoustic sensor networks (UASN).
  • By optimizing resource utilization and reducing wait times, the protocol enhances both network throughput and energy efficiency.
  • This advancement is crucial for applications requiring reliable and sustained data collection in underwater environments.
