In , we developed a novel SCM-based DSA mechanism that takes into consideration aggregate interference and makes use of frequency and power adjustments to deconflict spectrum use. We built a custom simulation platform to evaluate the algorithm’s performance, scalability, and feasibility in dynamic and dense communication environments. We plan to prototype and test this DSA mechanism on COSMOS soon.
A project funded in Dec. 2022 by an NSF grant from the Spectrum Innovation Initiative: National Radio Dynamic Zones (SII-NRDZ) program will expand on the efforts above and investigate and prototype a management system for spectrum sharing in NYC.
