ADDING NS2 IN ECLIPSE

 Now a days,running ns2 codes over ns2 is very useful and easy.If u want to speed up your programming and also you do not want to waste your time to remember Classes/APIs/Functions, do not want to waste time to open/close/reopen files, switch files back forth and finally, if you want to understand the code architecture better and quicker, you should use some good environment i.e IDE. In windows,the better IDE is visual studio.But in case of NS2,it is better to use Eclipse as the IDE for both linux and windows.In here we are explaining installation and working of Eclipse indigo and for ns2 versions (ns 2.31 to ns 2.35).


INSTALLATION OF ECLIPSE:

STEP 1: First,we have to download eclipse.And for that ,please go through following link;

                                              ECLIPSE DOWNLOAD

STEP 2: After downloading,open folder.It was normally in compressed format,so we have to extract it.Extract the IDE to a folder.

STEP 3 : Now download CDT from following link.
                                                  CDT DOWNLOAD

STEP 4: Now open Eclipse,go to help and then to install new software [Help--> Install New Software].A window with name "install" will pop up. Then go to Add. Put the values as shown below.

    Name:- CDT
    Location:- Browse to the "cdt-master-6.0.2.zip" file.

STEP 5: Check "CDT Main Features" and "CDT Optional Features", click next, then accept license and finish. At last it will ask you to restart Eclipse, then choose Restart.

CDT stands for “C/C++ Development Tooling”
If you do not have a working internet connection in the system you have installed Eclipse, instead of steps 4 and 5, download the CDT from the above mentioned site. Then move to Install New Software (STEP 4) -> Add and add the archive downloaded.

STEP 6: Now,install ns2, Download ns2 form here and then Extract NS-2 to a folder, i.e. /home/username/ns-allinone-2.35

Edit Makefile :

1. Open “…/ns-allinone-2.35/ns-2.35/Makefile.in” and

2. Add "-g" to the line CCOPT = @V_CCOPT@ as follows
                              CCOPT = @V_CCOPT@ -g

3. Add -DNDEBUG -DDEBUG to the end of the following line:
DEFINE = -DTCP_DELAY_BIND_ALL -DNO_TK @V_DEFINE@ @V_DEFINES@       @DEFS@-DNS_DIFFUSION -DSMAC_NO_SYNC -DCPP_NAMESPACE=@CPP_NAMESPACE@-DUSE_SINGLE_ADDRESS_SPACE -Drng_test -DNDEBUG -DDEBUG

4. Navigate to …/ns-allinone-2.34/ns-2.34 and run “./configure”

5. Navigate to the NS-2 folder using terminal and type ./install

6. Also, follow the instructions are displayed at the end of a successful installation. These instructions are to modify the PATH variable and other environment variables as needed.

7. You may encounter compilation troubles, due to the DEBUG flag being enabled. My experience was that several printf statements needed to be disabled (commented out):
                   mobile/shadowing-vis.cc line 293
                   aodv/aodv.cc line 210
                   aomdv/aomdv_rtable.cc line 186
                   aomdv/aomdv.cc line 283

ADDING NS2 IN ECLIPSE

STEP 7: Now once again open eclipse and set the workspace as the ns2 installation path (/home/user/ns-allinone-2.35) by selecting File -> Switch Workspace.

Choose File -> New -> Project -> C++ Project.

Select Project Type as Makefile Project -> Empty C++ Project.
            1. Toolchains: Linux GCC
            2. Enter Project Name as ns-2.34

Uncheck “Use default location” then browse to the directory NS-2 source directory ( …/ns-allione-2.35/ns-2.35 )

In Eclipse Indigo, you may not be allowed to create a new project in the existing ns-2.35 subfolder if you uncheck the “Use default location” checkbox. You will not need to, anyway, if you have chosen the parent folder as workspace. In this case, Eclipse will only warn you that you are creating a project in a directory which already exists.

Select “Next” and “Finish”.

From the workspace, Selecting the NS-2 Project and choosing Project -> Build All should not give Error.

Running the project must open the console with the NS-2 prompt, %

SETTING DEBUG CONFIGURATION

STEP 8: Select Run -> Debug Configurations

Choose C/C++ Application. Type in any name.

Under the Main tab, Choose the following:

Project as ns-2.34.

C/C++ Application as ns. (Search Project and Choose this)

Under the Debugger tab, choose GDB Debugger. Uncheck the “Stop on startup at” option.

Apply and Debug.

Link State Routing Protocol

Link state routing is a method in which each router shares its neighborhood’s knowledge with every other router on the internetwork. In this algorithm, each router in the network understands the network topology and then makes a routing table depending on this topology. Each router will share data about its connection to its neighbor, who will, consecutively, reproduce the data to its neighbors, etc. This appears just before all routers have constructed a topology of the network. In LSP, each node transmits its IP address and the MAC to its neighbor with its signature. Neighbors determine the signature and maintain a record of the combining IP address and the MAC. The Neighbor Lookup Protocol (NLP) of LSP derives and maintains the MAC and IP address of every network frame accepted by a node. The extracted data can support the mapping of MACs and IP addresses. The link-state flooding algorithm prevents the general issues of broadcast in the existence of loops by having every node mainta

HP NETWORK SIMULATOR: A COMWARE OS LEARNING TOOL

  Comware v7 is a network operating system that runs on HP high-end network devices. The HP Network Simulator is an ideal Comware v7 learning tool, which allows users to create, configure, and connect simulated networks. Benefits Beginners  – The HP Network Simulator tool is helpful for users who are new to networking and want to learn how to configure network devices (switches, routers), various topologies, or different routing and switching protocols and features. Experienced users  – The HP Network Simulator learning tool is helpful for users who have experience with non-HP networking devices and want to learn the Comware CLI and features. Extra devices  – Users can create devices using the HP Network Simulator and use them with their physical devices to configure and test topologies that aren’t configurable with just the physical devices they have. For example – A user wants to configure OSPF using 3 or more devices but has only 1 physical router. User can create 2 or more routers
