dct
在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中，发送者将载体图像分成8×8的像素块，每一块只精确地编码一个秘密信息位。嵌入过程开始时，首先伪随机地选择一个图像块bi，用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。
在通信开始前，发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致，让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频，确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失

BatchSimulation
As we know, the energy needed for sensors should be electrical. So the rst
step before start to work is to convert environmental energy to electrical one.
Inside the node there are dierent components for sensing the area, collecting
data and processing the data. So the main dierent part of this kind of nodes,
in compare of WSN nodes, is the power part. Once the stored energy reach
to a certain amount, the power supply for micro controller and transceiver will
start to work. They will continue to work until they have energy, as soon as the
energy nish, they stops and energy storage device start to work to save energy
again.
The other fact should be consider about EH-WSN node is that the available
energy can change in dierent nodes. So every node has its own harvesting rate.
