Wireless Sensor Networks (WSNs) are comprised of thousands of sensor nodes, with restricted energy, that cooperate
to accomplish a sensing task. Various routing Protocols are designed for transmission in WSNs. In this
paper, we proposed a hybrid routing protocol: Zonal-Stable Election Protocol (Z-SEP) for heterogeneous WSNs.
In this protocol, some nodes transmit data directly to base station while some use clustering technique to send
data to base station as in SEP. We implemented Z-SEP and compared it with traditional Low Energy adaptive
clustering hierarchy (LEACH) and SEP. Simulation results showed that Z-SEP enhanced the stability period
and throughput than existing protocols like LEACH and SEP.

FSK
数字频带通信系统
输入：首先输入模拟信号，给出此模拟信号的时域波形。
数字化：将模拟信号进行数字化，得到数字信号，可以选择PCM编码。
调制：可以选择简单的二进制数字调制方式。例如振幅键控(2ASK)、相移监控（2PSK）、频移键控（2FSK）、差分相移键控（DPSK）等。要求每个题目至少选择两种调制方式。有能力的同学也可以选择其它高效的调制方式?例如多进制数字振幅键控等?给出调制后信号的时域波形。
信道：假定信道属于加性高斯信道?或自行设计。
解调：相应的2ASK、2PSK、2FSK、DPSK解调，仿真获得解调输出波形。
PCM解码：给出解码后的模拟信号的时域波形，并与输入信号进行比较。
系统性能分析：比较在不同调制方式下，该数字频带传输系统的性能指标，即该系统的输出误码率随输入信噪比的变化曲线。(Digital frequency band communication system)

调整pdf的边缘及其行间距大小。首先把pdf保存为图片，然后用此程序调整边缘或行间距大小，把修改后的图片重新整合成pdf。此软件的目的是为了kindle用户编写。因为kindle的屏幕有限，除去多余的边缘和行间距，可以使kindle读书效率更高，减少过多翻页操作。(Adjust the line spacing pdf and the size of the edge. First, save the pdf as a picture, and then use this procedure to adjust the size of the edge or line spacing, the re-integration of the modified images into pdf. The purpose of this software is to kindle the user to write. Because of the limited screen kindle, to remove the extra edge and line spacing can make reading more efficient kindle, to reduce excessive flip operation.)
