Wireless networks performance varies from wired networks, the latter uses a guided medium and
wireless networks use unguided medium for transmission. To design and simulate wireless networks
the network simulator – 2 (NS – 2), an open source discreet event simulator could be used. The NS-2
simulator is a widely used simulation tool, which could generate trace files for analysis and comes
with a network animator to visualize the network performance.
This assessment requires students to compare and evaluate the performance of wireless routing
protocol using the NS – 2. The assessment requires students to design a wireless network topology in
NS – 2 and evaluate the generated trace files for a wireless routing protocol. The students are required
to carry out a critical analysis of the results of the protocol by plotting graphs and discussing the
The students are required to:
? Design a wireless network consisting of 25 nodes; the dimensions for the given topology are
1000×800. The agent type should be User Datagram Protocol (UDP) and the traffic Constant
Bit Rate (CBR). The simulation should run for 300 seconds. Random deployment of nodes is
required and the nodes are required to transmit packets over the network. The wireless node
configuration should include the NS – 2 energy model.
? Run the simulation on routing protocol Destination Sequenced Distance Vector Routing
(DSDV) and Ad hoc On DemandDistance Vector (AODV). Critically analyse the trace files in
terms of packets sent, received and dropped. These parameters should be plotted on graphs
and discussed in detail.
? Include screenshots of the NAM (Network Animator) displaying the nodes deployed during
the simulation and add screen shots of the simulation.
? Conduct comparative analysis on the results for packets sent, received anddropped for the
? Appendix I should include the tcl srcript used in each simulation.
