NS3-新增模块和调试

本周，应老师要求，为NS3新增lorawan-classB的模块。

模块的github地址：https://github.com/ConstantJoe/ns3-lorawan-class-B/tree/master/lorawan

下面是碰到的问题和经验总结。

1.如何在NS3.29中添加模块

To install this module, you should do as follow:
1. Download ns-3 latest version (ns-3-27) at [ns-3 main page](https://www.nsnam.org/ns-3-27).
2. Extract ns-allinone-3.27.tar.bz2 file.
3. Download ns3 lora module, then copy it ./src folder inside ns-allinone-3.27 folder.
4. Run three next statements to build source code:
```
	~/ns-allinone-3.27/ns-3$ ./waf clean
	~/ns-allinone-3.27/ns-3$ ./waf configure --enable-tests --enable-examples
	~/ns-allinone-3.27/ns-3$ ./waf build	
```

## Running the tests and examples

To test ns3 lora module, you run this statement:
```
	~/ns-allinone-3.27/ns-3$ ./test.py -s lora-node -m -t lora-node.txt
```
To run example of ns3 lora module, you run this statement:
```
	~/ns-allinone-3.27/ns-3$ ./waf --run lora-example

2.新装模块时碰到的问题
   1.build过程中报错

           lorawan/helper/lorawan-helper.cc:215:66: error: ‘DLT_LORATAP’ is not a member of ‘ns3::PcapHelper’

PcapHelper::DLT_LORATAP);

          因为使用的是C++编程语言，我对这方面了解很少（本科时候的欠账呀）。 一开始盲目去谷歌搜索（不得不说，谷歌在这方面是最好用的搜索引擎了）找不到相关信息。

          后来，静下心来，查看源文件   lorawan/helper/lorawan-helper.cc:， 215gg，定位到报错位置。发现作者细心的写了注释。 PcapHelper：： DLT_LORATAP, 而后定位类PcapHelper 位置 ：ns-3.29/build/ns3/tracer_helper.h. 根据注释，新增DLT_LORATAP = 270 解决问题。

          经验 ：报错了要去查看源文件，不盲目搜索

 

 

2.而后使用 ./waf --run 命令运行该模块中的example

碰到了一连串的问题，安装eclipse，在这个软件里编译和运行ns3模块，各个函数之间的依赖关系变得直观了。

ns3联合eclipse的安装方法（亲测可用）：

  如果碰到找不到路径的问题，请仔细确认，是使用绝对路径还是相对路径。

  那篇博客中的在我的eclipse june 2018（4.8.0）中未找到，暂时没发现影响。

 目前实现了对example中error问题的定位，具体的错误原因还待继续确定。。。。

 

 

 

 

 

 

具体碰到的问题：

NS版本 3.28 ，解决方法同3.29

 问题：lorawan/helper/lorawan-helper.cc:215:66: error: ‘DLT_LORATAP’ is not a member of ‘ns3::PcapHelper’

PcapHelper::DLT_LORATAP);

 

解决方法 ：在ns-allinone-3.28/ns-3.28/build/ns3/tracer_helper.h  line 61中新增  DLT_LORATAP = 270

 

运行example时, 3.28和3.29有相同的问题

不能运行的example

0. lorawan-error-distance-plot.cc 

问题 ： 找不到该模块  解决方法 在lorawan/examples/wscript 里将该example加进去

新问题：1. compling出错， 定位问题： lorawan-error-distance-plot.cc  line58  函数LoRaWANErrorDistanceCallback  的参数LoRaWANDataIndicationParams’ was not declared in this scope

 

 

  1， 3 有相同的问题
