		<description><![CDATA[
Classification of the Characteristics of Ad-Hoc Protocols and Routing-Strategies
Extension of Lang2003 and Murthy2004.
In general, routing can be divided into two strategies:
Adaptive Routing vs. Not-Adaptive Routing

 Adaptive: Changes of the network-topology are adapted by the routing-strategy
 Not-Adaptive: The routing is done using fixed tables


For Ad-Hoc-Netorks, only adaptiv strategies are usefull.
Reactive Routing/On-Demand Routing vs. Proactive Routing/Table-Driven Routing [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=dobbylove.wordpress.com&blog=4152724&post=67&subd=dobbylove&ref=&feed=1" />]]></description>

		<description><![CDATA[学习802.11的载波侦听机制，其实最重要的是了解 Physical Carrier Sense和Virtual Carrier Sense的不同，另外，NS-2里如何控制一个包能不能被接收到，能不能产生干扰的机制，也就是那几个关键的控制数值，如 CSThresh,RXThresh,Pr等等。这里解释一下：

1. 如果Pr &#60; CSThresh，那么无线网络接口将这个信号作为噪声而丢弃。
因此，MAC 层不能检测到这个载波。或者说，对于MAC 层而言，这个信
号是不存在的。
2. 如果CSThresh &#60; Pr &#60; RXThresh，无线网络接口将这个信号标记为错
误信号，然后上传给MAC 层进行处理。对于MAC 层而言，该信号可以
被检测到，但是不能被正确地解码。因此，MAC 层将该信号视为一个干
扰噪声。
3. 如果Pr &#62; RXThresh，无线网络接口直接将该信号上传给MAC 层。此
时， MAC 层可以对该信号进行正确地解码，并进行相应地处理。
在NS-2 仿真软件中，干扰范围的半径约为发射范围半径的2.2 倍。

		<description><![CDATA[Blogspot非常好用,但是自带的模板是不能让博客首页现实每个文章的摘要的,一下子就全显示出来,特不爽.于是找了点信息.改了一下.舒服了许多; )

1、在样式表中加入以下代码：

BORDER-RIGHT: 0px;
BORDER-TOP: 0px;
OVERFLOW: hidden;
BORDER-LEFT: 0px; BORDER-BOTTOM: 0px;
HEIGHT: 150px;
TEXT-OVERFLOW: ellipsis;
}
2、找到
改为以下代码：

这样以后发帖就不需要选择显示部分了，自动截取一部分显示出来

		<description><![CDATA[TCP流量的取得,先修改添加tcpsink,然后用perl脚本对tcpsink的trace进行分析:
 如下:
[Preparation for tcpsink]
1. Follow the steps of method2 at http://140.116.72.80/~smallko/ns2/tool_en.htm
2. Download mtcpsink.cc, mtcpsink.h
3. Put these two files into measure folder
4. Add the “measure/mtcpsink.o” in the OBJ_CC of Makefile
5. make clean; make
In tcl file:
&#8230;
set tcp1 [new Agent/TCP/Reno]
$ns attach-agent $s1 $tcp1
set tcpsink1 [new Agent/TCPSink/mTcpSink]
$tcpsink1 set_filename tcp_sink
$ns attach-agent $wl_node_(0) $tcpsink1
$ns connect $tcp1 $tcpsink1
set ftp1 [$tcp1 attach-source FTP]
&#8230;.

		<description><![CDATA[非常有用的很直接能看到flow的throughput的修改.利用loss-monitor,记录第一个包和最后一个包的抵达时间,然后计算出流量. 用于UDP.

A. Modification:
1. Modify the tools/loss-monitor.h
class LossMonitor : public Agent {
public:
LossMonitor();
virtual int command(int argc, const char*const* argv);
virtual void recv(Packet* pkt, Handler*);
protected:
int nlost_;
int npkts_;
int expected_;
int bytes_;
int seqno_;
double last_packet_time_;
//add the following two lines
double first_packet_time_;
int first;
};
2. Modify the tools/loss-monitor.cc
LossMonitor::LossMonitor() : Agent(PT_NTYPE)
{
bytes_ = 0;
nlost_ = 0;
npkts_ = 0;
expected_ = -1;
last_packet_time_ = 0.;
first_packet_time_ = 0.;
first=0;
seqno_ = 0;
bind(&#8220;nlost_&#8221;, &#38;nlost_);
bind(&#8220;npkts_&#8221;, &#38;npkts_);
bind(&#8220;bytes_&#8221;, &#38;bytes_);
