基于信道的历史信息来预测不同信道的未来可用时间可以帮助CR选择一个最佳信道进行信息传递。不同的预测准则应用到周期或是随机的开关模式中。一个CR可以学习以往不同信道的模式。我们提出一个简单的分类和学习方法去检测模式的类型和收集需要的信息用于智能信道的选择。MATLAB仿真结果显示提出的方案在随机信道的随机和周期模式中都有优越的表现。随着时间的变化，新到的切换次数减少到55 ，并且延迟时间也相应减少，而吞吐量却在提高。(Prediction of future availability times of different channels based on history information helps a cognitive radio (CR) to select the best channels for control and data transmission. Different prediction rules apply to periodic and stochastic ON-OFF patterns. A CR can learn the patterns in different channels over time. We propose a simple classification and learning method to detect the pattern type and to gather the needed information for intelligent channel selection. Matlab simulations show that the proposed method outperforms opportunistic random channel selection both with stochastic and periodic channel patterns. The amount of channel switches needed over time reduces up to 55 , which reduces also the delay and increases the throughput.)

Floyd算法的matlab实现。对输入的邻接距离矩阵计算图中任意两点间的最短距离矩阵和路由矩阵，且能查询任意两点间的最短距离和路由。并根据结果自动绘制出了最短路径图。 程序中使用了前向路由和回溯路由两种方法，并对于无向图进一步减小算法复杂度。(Matlab implementation of the Floyd algorithm. Adjacent input distance matrix between any two points in calculating the figure, the shortest distance matrix and routing matrix, and can query the shortest distance between any two points and routing. Automatically based on the results map out the shortest path graph. Used in the program prior to routing and backward routing are two methods, and undirected graph further reduce the algorithm complexity.)
