Sensing Data Allocation in Blockchain-Enabled Dynamic Spectrum Sharing with Distributed Storage

With the widespread adoption of internet of things (IoT) devices, dynamic spectrum sharing emerges as a technology for the efficient utilization of spectrum resources. To achieve this, sensing spectrum usage and maintaining collected information are essential for effective allocation decisions. In blockchain-enabled dynamic spectrum sharing, each IoT device collects and stores sensing data locally to automate spectrum sharing in a decentralized manner. However, IoT devices with limited storage find it challenging to participate because each IoT device must keep its sensing data. In this paper, we adopt a distributed storage technology within the blockchain-enabled dynamic spectrum sharing to store sensing data without depending on the storage capacity of individual devices. Additionally, we propose a sensing data allocation algorithm based on the value of sensing data and availability of participating device storage.
