- The future of wireless services and applications will increasingly rely on Dynamic Spectrum Access (DSA) methods to manage spectrum resources in a rapid and efficient manner
- We propose a novel spectrum management architecture, algorithm design, and experimentation framework that utilizes IEEE 1900.5.2 Spectrum Consumption Models (SCMs)
Spectrum Consumption Models
- Information model that allows RF devices to indicate their spectrum usage and interference protection needs
- Support methods to compute compatibility (i.e., non-interference) between any two models without dependence on external databases of environmental or system data
- Constructs: Reference power, spectrum mask, underlay mask, power map, propagation map, etc.
Spectrum Deconfliction Algorithm
- Algorithm leverages CIL (developed by DARPA) and SCM in the control plane to coordinate and exchange spectrum information
- Performs dynamic frequency and power adjustments of Tx/Rx devices
- Ensures aggregate compatibility with all devices in the system
ORBIT/COSMOS Experimentation Framework
Computation time per link (sec)
Baseline: Performs only frequency adjustment
- No PMT case represents max potential gain that can be achieved with the SD algorithm having an ideal power setting
- Baseline uses a large number of channels at full power
