中文摘要：
针对认知无线电网络可用频谱动态变化的特点和认知节点存在有意或无意丢包干扰问题,将跳数最少、鲁棒性强和路由安全等级高作为路由选择标准,提出了一种路由选择算法。跳数最少可简化数据传输过程;鲁棒性强可保证在可用频谱动态变化时,数据稳定传输,提高网络吞吐率;路由安全等级高可以减少由于转发节点存在的有意或无意干扰而引起的数据包丢失。给出了算法的具体实现步骤,理论分析和仿真实验表明该算法是高效和可行的。
英文摘要：
Aiming at the characteristics of the dynamic spectrum and the problem of intentional or tional packet loss interference in cognitive radio networks, the paper proposes a routing selection which takes least hops, high robustness and routing with high security level as routing selection st Least hops can simplify the process of data transmission, high robustness can ensure the stabilit3 transmission, and routing with high security level can reduce the behavior of dropping packets. T process of this algorithm is given. Theoretical analysis and simulation results show that the algorithm is and feasible.
