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 outcomes.
The students are required to:
Design a wireless network consisting of 15 nodes; the dimensions for the given topology are 500x400. The agent type should be UDP and the traffic CBR. The simulation should run for 200 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 DSDV or 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 displaying the nodes deployed during the simulation and add screen shots of the simulation.
