Area of Science:

• Computer Science
• Electrical Engineering
• Wireless Communication

Background:

• Wireless multimedia sensor networks (WMSNs) face centralization challenges due to large multimedia data volumes.
• Device-to-device (D2D) communication is crucial for enhancing WMSN capabilities, particularly within cellular network infrastructures.
• The integration of D2D communication in WMSNs creates complex interference environments, necessitating effective management strategies.

Purpose of the Study:

• To propose and evaluate an interference mitigation scheme for D2D WMSNs operating within cellular networks.
• To address the challenges posed by complex interference environments arising from non-orthogonal frequency usage in D2D WMSNs.
• To improve the overall network throughput by effectively managing varying inter-cell interference.

Main Methods:

• A novel interference mitigation scheme is proposed for D2D WMSNs.
• Each cell is partitioned into six distinct zones for orthogonal frequency allocation to cellular links.
• Frequencies allocated to cellular links are intelligently reused by D2D links in adjacent zones.

Main Results:

• The proposed scheme effectively manages complex interference environments in D2D WMSNs.
• Simulation results demonstrate a significant improvement in network throughput.
• The throughput achieved with the proposed scheme is double that of static frequency allocation methods.

Conclusions:

• The developed interference mitigation scheme is highly effective for D2D WMSNs.
• Optimized frequency allocation strategies are key to enhancing throughput in complex wireless environments.
• The findings offer a practical solution for improving the performance of next-generation WMSNs.
