Area of Science:

• Sensor Networks
• Surveillance Technology
• Optimization Algorithms

Background:

• Perimeter barriers are crucial for intrusion detection in areas like coastlines and borders.
• Irregular boundaries necessitate robust coverage strategies, often involving circular representations.
• Bistatic Radar Sensor Networks (BRSNs) offer potential for effective perimeter surveillance.

Purpose of the Study:

• To develop optimized sensor placement for circular barrier coverage in BRSNs.
• To address the challenge of constructing circular barriers with a predefined width and minimum detectability.
• To minimize deployment costs while maximizing coverage effectiveness.

Main Methods:

• Developed cost-driven placement sequences considering unit sensor costs.
• Proposed two segmentation strategies (Circular Equipartition and Adaptive Segmentation) for wider circular barriers.
• Formulated approximate optimization algorithms for minimum cost sensor placement.

Main Results:

• Optimized BR placement patterns for single circular barriers were identified.
• Cost-effective sensor placement sequences were derived.
