Vertical Handoff Algorithm

在异构无线网络中关于垂直切换算法的代码，描述了相关的概率计算，卡尔曼滤波计算等。(In the heterogeneous wireless network, the code about the vertical handoff algorithm is described, which describes the related probability calculation, the Calman filter calculation and so on.)

在异构网络垂直切换中，通过AHP+TOPSIS算法得到在四种业务类型中的权重，从而绘出的直方图(In the vertical handoff of heterogeneous networks, we get the weights in four business types by AHP+TOPSIS algorithm, and draw the histogram.)
