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。

Abstract:

Sensor management is an important component of multisensor fusion systems. Since there exists the lack of an efficient method for multisensor fault control of sensor management, a method of sensor management based on the finite state automata (FSA) is proposed. Firstly,different control strategies for sensor management are modeled by the real language measure. The legal behavior of control strategy modeled by FSA can generate a partially ordered set of controlled languages. Then an identification method of the language measure parameters based on an FSA model is proposed. The language measure creates a total ordering on the performance of the controlled languages. The experiment validates that FSA model can design sensor fault control strategies, and the language measure can evaluate the performance of the different control strategies effectively.
