Resource selection matching algorithm in underlay cognitive radio networks

In this paper, the resource allocation in an underlay cognitive radio network is considered, in which the SUs can operate on the same spectrum band with the primary users simultaneously. In order to maximize the total throughput of SUs, an optimal selection matching (OSM) algorithm is proposed to allocate the resource in the underlay cognitive radio network. It makes every SU find the satisfied spectrum resource, and meanwhile the interference from SUs is induced. Simulation results show that the proposed algorithm has the significant improvement in total throughput compared with others.
