A real-time network level platform for dynamic spectrum sharing systems

A real-time network level platform (DySNet) for dynamic spectrum sharing network is presented. A dynamic spectrum sharing network takes the opportunistic use of dynamic changing spectrum. It also dynamic changes its working spectrum to avoid interference to primary users. To support research on the network level of cognitive radio, The DySNet has capability of sensing the spectrum, it also support transmitting and receiving signals to form a complete radio node in a wireless network. It has flexibility and scalability to meet different requirements of researches. A center based network, a distributed network and a hybrid network has been implemented on DySNet.
