Effective Spectrum Management in Crowded Areas using SDR

Dynamic Subcarrier Allocation with Priority Weighting to avoid interference with primary users..

In crowded wireless environments (e.g., urban areas, IoT networks), spectrum is often heavily used. Effective spectrum management is crucial to:

1. Avoid interference with primary users.
2. Maximize utilization of underused spectrum.
3. Dynamically allocate resources based on demand.

Priority Weighting: Assign priority to secondary users based on:

Signal demand, Quality of service requirements and Interference tolerance

1. Dynamic Allocation: Allocate free subcarriers preferentially to high-priority users.
2. Adaptive Power Control: Assign more power to higher-priority users in free subcarriers.
3. Feedback Loop: Continuously sense the spectrum and adjust allocations (like SDR real-time adaptation).

This approach allows crowded areas to share spectrum efficiently and ensures fairness and high throughput.
