Abstract :
Distributed cognitive radio network shares the spectrum with the primary network. Generally the aim is to maximize the number of secondary users in the network without degrading the primary network´s performance. For this, we use a distributed power allocation scheme in this paper. The power of the secondary users is found using the power allocation algorithm and substituted into the utility functions of the primary and secondary users. The simulation results prove that the power allocation algorithm maximizes the throughput of the network without causing much interference to the primary network.
