Abstract:
This paper introduces an extension of a methodology for calculating the throughput in a cognitive radio network using the slotted aloha technique for medium access. This extension includes two new aspects: imperfect sensing and different transmission power levels in the secondary stations. The performance of the network is evaluated and numerical results are compared with the results for the original model. The new aspects considered in this paper make the model more realistic
