A Network Simulation Platform for Hierarchical Spectrum Sharing Based Cognitive Radio Network

Recently, a new cognitive radio network architecture named after hierarchical spectrum sharing network (HSSN) is proposed to improve the utilization of the spectrum resource by taking the time and spatial dimensions of spectrum resource into account. For testing and verifying performance and reliability of algorithms and protocols for HSSN, evaluating HSSN network performance and the level of interference to PUS, we develop a network simulation platform for HSSN (SPHSSN) in this paper.
