Description: 网络损伤仪软件，绝对独家！！
用来模拟网络对报文的损伤。从一个网卡上输入网络数据流，你可以自己随意模拟一定的延迟，模拟个性化的丢包，甚至抖动等，你要做的就是修改宏变量的参数即可。从另一张网卡流出的就是经过模拟损伤的网络流。只需要一台PC机就可以模拟例如路由器、交换机、无线网络等等可能带来的损伤，大大帮助研究和网络的开发和测试。一台硬件损伤仪市价至少五位数-Network Software injury, absolutely exclusive! ! Used to simulate the network packet damage. From a network adapter on the input data stream, you can own a certain degree of delay random simulation, simulation personalized packet loss, jitter, etc. and even, you have to do is modify the parameter macro variables. Another card from the outflow is through the network flow simulation of injury. Units need only one PC machine can be simulated such as routers, switches, wireless networks and so on may be brought about by injury and contributes significantly to the research and network development and testing. Units 1 Miriam hardware damage market value of at least five digits! !

Description: 自己编写的关于无线脚本的trace文件分析awk文件。
在无线网络层仿真中，使用NS2软件的必修课就是使用AWK文件分析TRACE文件。
我所写的网络层方面的仿真大多都用这几个文件作分析--时延、吞吐量、抖动、剩余能量、丢包率。希望对你有用。-Awk file decoded by myself which can analysis trace file in wireless scenery.
In wireless simulation on network layer, using awk file to analysis trace file is inevitable.
i always use these awk file to analysis delay, throughput,jitter, residual energy and loss rate. I hope it can help you.

Description: JITTERBUG 是一个用来仿真线性控制系统的Matlab工具箱。通过JITTERBUG，我们能得到延时、数据丢失对系统的性能影响。同时，这个工具箱还能计算控制系统中信号的谱密度。-JITTERBUG [Lincoln and Cervin, 2002] is a MATLAB-based toolbox that allows
the computation of a quadratic performance criterion for a linear control
system under various timing conditions. Using the toolbox, one can easily
and quickly assert how sensitive a control system is to delay, jitter, lost
samples, etc., without resorting to simulation. The tool is quite general and
can also be used to investigate jitter-compensating controllers, aperiodic
controllers, and multi-rate controllers. As an additional feature, it is also
possible to compute the spectral density of the signals in the control system.
The main contribution of the toolbox, which is built on well-known theory
(LQG theory and jump linear systems), is to make it easy to apply this
type of stochastic analysis to a wide range of problems.
