Approach
To address the challenges of traditional spectrum management, this project introduces a decentralized spectrum sharing system enabled by blockchain technology. The following diagram illustrates how the system operates:
Figure 1: Overview of the Decentralized Spectrum Sharing System
The decentralized spectrum sharing system involves multiple servers and spectrum slices, granting access based on priority. Type One users (Priority Users) are allocated resources with high priority, while Type Two users (Unlicensed Users) are granted access conditionally.
Our system leverages blockchain technology to automate spectrum allocation and ensure compliance with regulations. The architecture is designed to handle requests, store metadata, and allocate spectrum resources efficiently.

The architecture comprises several key components:
- Spectrum Request Module: Handles user requests,validates input and creates an interface with the Spectrum Allocation Module.
- Spectrum Allocation Module: Processes pending requests and allocates spectrum resourcesdynamically based on priorities.
- Blockchain State: Stores requests, allocations, and channel metadata, ensuring transparency and immutability.
- Event Notification: Notifies external systems of successful or failed requests.
This architecture ensures fair and transparent spectrum resource distribution, real-time spectrum allocation, and seamless user notifications through blockchain's decentralized nature.
