Abstract: In order to improve the effective utilization of the spectrum between the network and users, this paper proposed the allocation scheme for dynamic cognitive user based on the spectrum allocation of the Internet of things. Based on the advantage of the network performance framework of spectrum of the internet of things, this paper analyzed the dynamic network user model of the spectrum, established a good resource hierarchical distributed management structure, provided support for the resource sharing and coordination between multiple heterogeneous network; then gave the spectrum of the network resource allocation algorithm of things. Finally, the simulation experiment performance comparison for the new spectrum network and traditional network model was made. The results showed that the new spectrum resource allocation scheme of things was significantly better than the traditional cooperative sensing detection performance in the right perception of cognitive network cooperation performance, which can improve perception of network nodes, with network throughput and stability.
