Area of Science:

  • Computer Science
  • Electrical Engineering
  • Oceanography

Background:

  • Underwater acoustic sensor networks (UASNs) face unique challenges due to the acoustic channel, differing significantly from terrestrial wireless sensor networks.
  • Sink-oriented UASN architectures suffer from the funneling effect, causing congestion, collisions, and packet loss near the sink due to increased traffic load and long propagation delays.

Purpose of the Study:

  • To propose an improved Code Division Multiple Access (CDMA)-based Media Access Control (MAC) protocol for UASNs.
  • To address the funneling effect and enhance network performance in terms of throughput and end-to-end delay.

Main Methods:

  • Developed a novel Path-Oriented Code Assignment CDMA MAC (POCA-CDMA-MAC) protocol.
  • Integrated a round-robin method with CDMA technology to enable simultaneous packet reception from multiple paths at the sink.
  • Utilized shorter spreading codes compared to Transmitter-Oriented Code Assignment (TOCA) and Receiver-Oriented Code Assignment (ROCA) protocols.

Main Results:

  • The POCA-CDMA-MAC protocol allows the sink to receive packets from multiple paths concurrently.
  • The protocol significantly reduces the length of spreading codes required, easing implementation.
  • Simulation results demonstrate higher network throughput and lower end-to-end delay compared to existing CDMA-based MAC protocols.

Conclusions:

  • The proposed POCA-CDMA-MAC protocol is an effective solution for mitigating congestion and packet loss in UASNs.
  • This protocol offers superior performance in terms of throughput and delay, making it suitable for demanding underwater communication scenarios.
