Implement an NS2 LTE simulation with sumo and Ad-hoc network

|▌冷眼眸甩不掉的悲伤 提交于 2019-12-10 11:47:13
问题 Hello everyone I want to ask for your valuable help to see if it is possible to add a SUMO scenario I have into NS2 to be able to simulate an ad-hoc network between cars and also allowed them to communicate with an LTE radio base station (eNodeB). I already have SUMO and NS2 with the LTE patch running, I was able to add the LTE features thanks to an answer given by Knud Larsen in this post: invalid command name "Queue/LTEQueue" 回答1: Ref. your note "7" https://drive.google.com/drive/folders

Simulating packet dropping in a wireless network

问题 How can I simulate a packet be dropped from a malicious node in a wireless network using ns2? 回答1: First you need to modify aodv.cc and aodv.h files. In aodv.h after /* The Routing Agent */ class AODV: public Agent { ... /* * History management */ double PerHopTime(aodv_rt_entry *rt); ... add following line bool malicious; With this variable we are trying to define if the node is malicious or not. In aodv.cc after /* Constructor */ AODV::AODV(nsaddr_t id) : Agent(PT_AODV),btimer(this), htimer

CentOS7配置 DNS

DNS (Domain Name Service) 域名服务是计算机网络很基础的服务,一般如果局域网内计算机多了,可以考虑搭建一个内网 DNS,将 IP 地址转换为名字,这样记起来更容易。 环境说明 CentOS 7(Minimal Install) 样例说明 本例需要 4 台服务器 10.11.0.199 ns1 10.11.0.209 ns2 10.11.0.101 host1 10.11.0.102 host2 ns1 为主 DNS,ns2 为次 DNS,host1,host2 分别为注册的主机(注意: host1, host2 不是机器名,因为机器名跟 DNS 没关系,host1, host2 是 DNS 里配置的) 具体说明如下: 我们使用 2 个服务器 host1 和 host2 服务器在一个机房内,本例为北京机房(bj1 datacenter) 机房内的服务器网络是相互联通的(本例都在 10.11.0.0/16 子网内) 本机房使用 example.com 这个域名(实际情况请自行更改,注意最好使用自己的域名,这样可以保障不会出现重复等冲突) Host Role Private FQDN Private IP Address host1 Host host1.bj1.example.com 10.11.0.101 host2 Host host2.bj1

make command not working in NS 2.35

I am trying to modify AODV routing protocol using NS 2.35. I have made some changes to the files aodv.cc and aodv.h. Now, to apply these changes I have run a make command inside ns-allinone-2.35/ns-2.35 folder and getting the following error message: In file included from aodv/aodv_logs.cc:31:0: ./aodv/aodv.h:53:18: fatal error: list.h: No such file or directory #include <list.h> ^ compilation terminated. make: *** [aodv/aodv_logs.o] Error 1 How will I solve this? #include <list.h> is ignored in a default ns2. If changes are made, the non existing 'list.h' can sometimes be called. You can

Ubuntu16.04:NS2安装与入门

扶醉桌前 提交于 2019-12-02 15:15:13
NS2是一个全开源的比较成熟的网络模拟器,与之相对有的有商业付费软件OPNet。因为工作需要,所以对NS2进行了调研,安装并简单使用了一下,做个记录。NS2在2011年就已经不维护了,这算是考古了。 一:NS2简单介绍 NS2是面向对象的、开源的离散事件模拟器。可用于仿真各种不同的IP网,实现有一些MAC层协议。注重低级协议仿真,监视, 分析包踪迹和队列行为 。 NS2采用系统编程语言C++和脚本编程语言OTcl共同开发。NS2作为OTcl的脚本解释器,由 事件调度器 、 网络组件对象 和 网络组装模块库 组成,其中事件调度器和网络组件(协议实现由C++完成),仿真配置由Tcl脚本实现。 二:NS2的安装 其实有很多博客都说到了NS2的安装,也说的很好。这里就简单说一下: 参考: https://blog.csdn.net/liyongqi_/article/details/71774170 https://blog.csdn.net/mingyong_blog/article/details/41114421 1. 首先是NS2源码的下载,下载地址: http://www.isi.edu/nsnam/ns/ns-build.html ,下这个就好了。 2. 然后就是依赖工具包的安装: sudo apt-get install build-essential sudo apt
