Outline of Final Research Achievements |
In this research project, we considered autonomous distributed mechanisms for cooperative sensing in cognitive radio networks with an extremely huge number of wireless nodes. We proposed two schemes: collaborative spectrum sensing mechanism based on system load and detection performance of wireless nodes, and a coalition formation method based on machine learning technique. In the former scheme, we developed the merge-split algorithm with incentive mechanism under game theory, while the latter was developed with Multi-Armed Bandit problem. We investigated the performance of proposed methods by simulation experiments, validating those effectiveness quantitatively.
