Smart Underwater Sensor Network GPRS Architecture for Marine Environments.

Area of Science:

• Computer Science
• Electrical Engineering
• Marine Science

Background:

• The Internet of Things (IoT) enables new communication paradigms like underwater IoT (UIoT).
• UIoT facilitates the interconnection and monitoring of marine assets, including vessels, marine life, and environmental sensors.
• Aquatic sensor networks face challenges like limited bandwidth, propagation distance, and data transmission delays.

Purpose of the Study:

• To propose and evaluate a novel architecture for a General Packet Radio Service (GPRS) wireless sensor network tailored for underwater environments.
• To enhance network coverage and optimize energy efficiency for aquatic monitoring applications.
• To address the limitations of current aquatic mobile sensor nodes.

Main Methods:

• Development of an integrated architecture combining cellular technology and ad hoc network configurations within a single device.
• Implementation of a GPRS wireless sensor network for monitoring geographic positions in the Gulf of Mexico's coastal area.
• Evaluation of network coverage using a proposed channel model analyzing signal attenuation.
• Assessment of energy consumption by examining the electronic system's autonomy.

Main Results:

• The proposed architecture successfully integrates cellular and ad hoc networking, improving network coverage.
• Energy consumption was maintained at acceptable levels without significant impact.
• The system demonstrated effective geographic positioning monitoring in the coastal Gulf of Mexico.

Conclusions:

• The developed GPRS wireless sensor network architecture offers a viable solution for improving underwater IoT communication.
• The integration strategy effectively balances enhanced coverage with energy efficiency for aquatic sensor networks.
• This approach supports persistent remote monitoring and surveillance in marine environments.
