Abstract (Summary)

Cognitive radios are the external sensing agents for the secondary users to improve the Dynamic Spectrum Access (DSA), to overcome the primary user’s problems, and to improve the spectrum utilization. External sensors create the opportunities for the DSA networks to utilize spectrum access within the cellular frequency bands. In this project, a method based on co-operative matching is presented, to overcome the difficulties of managing the detected spectrum by the external sensors.

The spectrum access resources detected are divided into two types of blocks: massive block size and small block size. In massive block size, secondary users follow wholesale sharing and in the small block size, users follow aggregation sharing. Distributed Fast Spectrum Sharing (DFSS) algorithms reduce the delay in spectrum sharing. Simulation results show that the DSA networks can access 95% of the detected spectrum using a DFSS algorithm.
