ICN-Based Radio Spectrum Sharing via Preliminary Data Publishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio spectrum sharing techniques face inefficiencies due to the need for constant communication between incumbents and potential users, leading to significant processing overhead, especially as the number of IoT devices increases, and result in complex networks and high costs.
Innovation Solution
The implementation of Information-Centric Networking (ICN) enables efficient radio spectrum sharing by allowing devices to request named data or spectrum blocks, reducing redundant traffic and enabling aggressive caching, while fine-grained encryption ensures secure communication, thereby minimizing the need for constant requests and reducing network complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If constant communication between incumbents and potential users is maintained to enable spectrum sharing, then spectrum utilization efficiency is improved, but processing overhead increases significantly
Solution Approach 1:
The patent implements preliminary action by having the incumbent publish spectrum availability information in advance through a data packet in the ICN network. This allows potential users to proactively retrieve availability data without needing to constantly communicate with the incumbent, thereby maintaining high spectrum utilization while significantly reducing processing overhead. The incumbent performs the action of publishing availability information beforehand, eliminating the need for continuous real-time communication.
2Quantity of substance
If the number of IoT devices increases to utilize available spectrum, then spectrum sharing capacity is improved, but network complexity increases
Solution Approach 1:
The patent applies universality by implementing a single ICN-based data packet publishing mechanism that serves all potential users regardless of the number of devices. The incumbent publishes spectrum availability information once, and any number of potential users can retrieve this information independently through the ICN network without requiring individual communication channels or coordination. This universal approach allows the system to scale to large numbers of IoT devices while maintaining simple network architecture.
3Adaptability or versatility
If traditional communication protocols are used for spectrum sharing, then device compatibility is maintained, but redundant traffic increases
Solution Approach 1:
The patent implements copying by having potential users retrieve spectrum availability information from the ICN network data packet rather than receiving repeated individual communications from the incumbent. The availability information is published once as a data packet that can be copied and cached by multiple potential users simultaneously. This eliminates redundant traffic while maintaining compatibility, as users can independently retrieve and use the published information without requiring continuous protocol-based communication with the incumbent.

AI summary
System and techniques for radio spectrum sharing are described herein. A free radio spectrum block may be identified. An identification packet of the free radio spectrum block may be published. Here, the identification packet may include at least one of available spectrum, time, or area corresponding to the free radio spectrum block. An acknowledgement to the identification packet may be received. A provider of the free radio spectrum block may then be caused to cease radio communication on the available spectrum for the time and area specified in the identification packet.
