QualNet Simulator

Assignment 4

Use QualNet simulation tool to show the comparison of adhoc routing protocols: AODV and DSR.

Consider varying packet size, number of nodes, bandwidth and bit error rate for comparison.

Repeat a QualNet simulation with different seed values for example 1,2,3,4 and 5. You should NEVER

just run one simulation, with one seed value, and claim that you have a good understanding of the

performance of the protocol. You need to see how the protocol reacts in a wide variety of topologies

to understand its performance. In mobile networks (and even in wired networks), strange anomalies

can occur in one network topology that do not occur in others. Hence, if you only examine the

results from the one topology with the anomaly, you may not be able to understand your results.

Use the following input parameters for your simulations. If a particular input parameter is not listed,

just use the default value that comes with QualNet.

MAC protocol: 802.11

Routing protocol: AODV

Mobility protocol: Random Waypoint

Mobility speeds: 0-10m/s

Pause time: 10seconds

Number of nodes: 50

Network terrain dimensions: 1000m x 1000m

Transmission range: 250m (*exactly*)

Bandwidth: 2Mbps

Traffic type: CBR

Source nodes: 1, 2, 3, 4, 5

Destination nodes: 6, 7, 8, 9, 10 (respectively)

Data packet size: 64 bytes

Packet generation rate: 10 pkts/sec (at each source)

Number of packets to send in each session: 1000

Simulation length: 200 seconds

Data session start time: Start first session at 10 seconds, and start the following ones every

5 seconds after the previous one.

For the above parameters, run simulations with SEED values 1, 2, 3, 4, and 5. Save your results from

each simulation run so that you can average the results together. You will need to determine how to

set the transmission range.

After running the five simulations, compute the averages for the following metrics. These values

should be an average of each session within a simulation, and then should be averaged over all seed

values.
