Wireless Sensor Networks (WSNs) can real-time monitor, collect and process all kinds of information. They have wide applications. The demands of spectrum in WSNs rose sharply, thereby how to deal with the spectrum allocation of WSNs is a difficult problem. A dynamical and real-time spectrum allocation system is proposed, which was based on the network architecture of Internet of things by the means of Cognitive Radio and cloud computing, it include Cloud resource scheduling configuration, Real-time data memory, Distributional policy-making support and so on. Dynamic spectrum allocation system of WSNs assigned the spectrum dynamically and real-timely that it can improve the spectrum utilization rate. This system is an efficient path to face the spectrum needs of WSNs.
