Self-Adjustment Energy Efficient Redeployment Protocol for Underwater Sensor Networks

Area of Science:

• Marine technology
• Network engineering
• Oceanography

Background:

• Underwater Sensor Networks (UWSNs) are crucial for ocean exploitation and monitoring.
• Random initial deployment of UWSNs often results in poor network coverage and connectivity.
• Network deployment significantly impacts overall UWSN performance.

Purpose of the Study:

• To propose a self-adjustment redeployment protocol for UWSNs.
• To enhance network coverage and connectivity.
• To reduce energy consumption during UWSN deployment.

Main Methods:

• Investigating the impact of water currents on UWSN deployment.
• Developing a protocol to exploit water currents for node repositioning.
• Simulating the proposed protocol to evaluate its effectiveness.

Main Results:

• Achieved a 97% coverage rate for the network area.
• Reduced the total distance traveled by underwater sensor nodes by 41%.
• Demonstrated enhanced network coverage and connectivity.

Conclusions:

• The proposed self-adjustment redeployment protocol effectively improves UWSN deployment.
• Leveraging water currents is a viable strategy for optimizing UWSN performance.
• The protocol offers significant energy savings and improved network reliability.
