Abstract |
The success of cognitive radio network (CRN) depends upon the accurate spectrum sensing. The hidden and open terminal problems are serious threats in the way of reliable communication. Cluster based architecture with cooperative spectrum sensing is widely adapted to overcome these challenges. In this paper, we propose a cluster based architecture with overlapping antennas. The number of overlapping antennas increases the overall performance of the system by improving the accuracy of detection. But on the other hand the overlapping antennas, increases the over heads of the system as well. So in order to achieve a balance between efficiency and system overhead, optimal numbers of overlapping antennas are suggested in this paper. Mathematical model along with simulations are presented in this paper which guarantees the sufficient number of overlapping antennas in the cluster. |
