Comparison of AODV, DSR and DSDV Routing Protocols in ns2 - NS2 Tutorial # 9

Comparison of AODV, DSR and DSDV Routing Protocols in ns2 - NS2 Tutorial # 9 Very old Project as well as a topic, but this will give an idea of how to compare multiple protocols or agents. #AODV #DSR #DSDV #NS2 1 hour Project* - you should know ns2 already should know how to write AWK scripts Should know about energy model Should know about wireless networks and protocols To know the above concepts, check my Ns2 Lecture series videos in Youtube and come back to this video    / tspradeepkumar   AODV, DSDV and DSR AODV - Adhoc On Demand Distance Vector DSDV - Destination Sequenced Distance Vector DSR - Dynamic Source Routing Lcture 8 - AWK Scripts Average throughput Instant throughput Residual Energy Packet Delivery ratio To download the source codes, visit https://www.nsnam.com Going inside the project Step 1: Use the same network and same disntace, energy, etc when you compare multiple protocols Step 2: Generate Scenario, You need not write the code in TCL (of course you can modify). We use NSG for creating a network. Refer my lecture series on NSG (NS2 scenario Generator) $] java -jar NSG2.1.jar As seen in the GUI, Create a network (for example with 17 nodes) and two nodes are moving with a interference of 550 metres and tranmission range of 250metres. Create a network with a AODV protocol Create two copies of AODV protocol and name it as DSR.tcl and DSDV.tcl $] cp AODV.tcl DSR.tcl $] cp AODV.tcl DSDV.tcl Three files are ready now called AODV.tcl, DSR.tcl, DSDV.tcl and now these three files using ns filename.tcl $] ns AODV.tcl $] ns DSR.tcl $] ns DSDV.tcl I have the three files and got 9 files namely AODV.tr, DSDV.tr and DSR.tr AODV.nam, DSDV.nam and DSR.nam There is no energy coding, i need to implement that DSR does not obey the queue model as specified for AODV, Queue/DropTail/PriQueue is not supported by DSR, we have to go for CMUPriQueue DSR supports this queue called CMUPriQueue, it should reflect in the tcl code. All the tcl files run successfully. now we are going to analyse the results and sometime plot the graphs too. we have already written AWK scripts for Average throughput, instant throughput , residual energy and packet delivery ratio average_throu.awk instant_throu.awk pdr.awk resenergy.awk To run these scripts we need awk interpreter as below $] gawk -f resenergy.awk AODV.tr $] gawk -f resenergy.awk DSDV.tr $] gawk -f resenergy.awk DSR.tr Whenvern you compare multiple protocols Use three different sets of nodes Small number of nodes (10 nos) Medium number of nodes (20 to 30 nos) Huge number of nodes (upto 100) beyond 100 nodes, ns2 suffers. in this case, we did it for 17 nodes only. You can do the rest. So we are coming to the conclusion Comparing protocols needs 1. Three minimum protocols (AODV, DSR, DSDV) TCP, TCPReno, TCPVegas, FullTCP 2. number of nodes (small, medium and huge) as mentioned above, 10 nodes, 30 nodes, 100 nodes 3. Atleast three performance metrics, in this case we have, average throghput, instant througput, residual energy and packet delivery ratio 4. Strong knowledge on the protocols 5. AWK scripts to be known or atleast to be downloaded. 6. Design the network rather than coding the network, use scenario generators for ns2. Our project is complete!!!
