摘　　要：针对面向传感网络设计的簇和数据路由算法无法直接应用于认知无线传感网络的问题,给出一种认知无线传感器网络中基于簇的地理位置路由方案。所给方案先利用频谱感知信息与剩余能量构建簇,然后把剩余能量大于阈值且距离信宿更近的节点作为下一跳转发节点,从而使得具有最低通信成本的路径传输数据。仿真结果表明,相比于基于频谱感知的簇多媒体路由方案和移动增强的可靠机会路由方案,所给方案在能耗和端到端传输时延方面均能得到有效控制,所给方案的能耗降低了6.0%~9.2%,平均时延降低了8.6%~16.2%。To resolve the problem that the cluster and data routing algorithm designed for sensor network cannot be directly applied to cognitive wireless sensor network,a cluster-based geographical location routing scheme for cognitive radio sensor network is proposed.The proposed scheme firstly uses the spectrum sensing information and residual energy to build the cluster,and then takes the node closer to the home and the residual energy greater than the threshold as the next hop forwarding node,so as to make the path of data transmission with the lowest communication cost.The simulation results show that the proposed scheme can effectively control the energy consumption and end-to-end transmission delay by comparing with spectrum-aware clustering for efficient multimedia and mobility-enhanced reliable opportunistic routing.The energy consumption of the proposed scheme is reduced by 6.0%~9.2%,and the average delay is reduced by 8.6%~16.2%.
