  • To overcome the multi-channel hidden terminal problem in distributed cognitive wireless networks as well as improve the performance of the network, a general convex programming model is formulated. The access probability of each cognitive user can be derived from this model. A Distributed Spectrum Access Control (DSAC) algorithm is proposed based on convex optimization. The simulation results show that DSAC can converge during a few intervals, and DSAC can also increase the number of transmission links in the network so as to improve the spectrum efficiency and the network throughput.
