| Outline of Final Research Achievements |
Main concern of this paper is to provide efficient ad-hoc communication over the cognitive radio network. To provide efficient ad-hoc communication without performance degradation to primary user, the share of wide range of information such as neighboring nodes and available channels (white spaces) is crucial for switching communication channel spatiotemporally. In this project, I proposed two sorts of common control channels, which are for (1) grasping the neighboring nodes and (2) sharing the white space information among communication nodes. These common control channels are established and maintained in a distributed manner. The effectiveness of the proposed scheme was evaluated through simulation experiment.
