摘　　要：将动态频谱感知与无线传感器网络相结合,提出一种频谱分配算法,它能在避免对授权用户产生干扰的同时,根据一定的分配规则,提高传输可靠性及频谱利用率。通过仿真证明,该算法可减少网络节点在传输过程中发生频谱切换的概率,从而降低了节点能耗;同时数据包成功传送到接收端的比例也比同类算法有所提高。Wireless sensor network is combined with dynamic spectrum sensing technology,and a spectrum allocation algorithm is proposed. The algorithm can improve the transmission reliability and the spectrum utilization rate by adopting some allocation schemes. It can also avoid interference to authorized users. The simulation demonstrated that this algorithm can reduce the spectrum handoff to save the energy, and the transmission success rate is also higher than that of the similar schemes.
