Wireless Networks and Security Assignment - Wireless networks performance evaluation
Purpose of the assessment (with ULO Mapping) - The purpose of the assignment is to compare the wireless communication technologies and evaluate their performance. Students will be able to complete the following ULOs:
a. Compare standards-based technologies used in various networks;
b. Test and evaluate various wireless networks performance;
Assignment Description =
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 protocols using the NS-2. The assessment requires students to design a wireless network topology in NS-2 and evaluate the generated trace files for two different wireless routing protocols. The students are required to carry out a critical analysis of the results of the two routing protocols, by plotting graphs and discussing the outcomes.
The students are required to:
- Design a wireless network consisting of 20 nodes; the dimensions for the given topology are 400x300. The agent type should be UDP and the traffic CBR. The simulation should run for 300 seconds. Uniform 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 two different routing protocols such as DSDV, AODV, DSR, and TORA. Critically analyse the trace files in terms of packets sent, received, dropped and energy consumed. These parameters should be plotted on graphs and discussed in detail.
- Include screenshots of the NAM displaying the nodes uniformly deployed during the simulation and add at least 3 screen shots of the simulation.
- Appendix I should include the tcl srcript used in each simulation.
Sections included in the report -
1. Introduction - Outline of the report (in 3-4 sentences).
2. Report Layout - Report layout, style and language.
3. Network Design - The network topology shown in the NAM.
4. Simulation - Three simulation screen shots for each routing protocol at 50s, 150s and 250s simulation time with description of the ongoing events.
5. Trace file analysis - Provide a critical analysis of the two trace files in terms of packets sent, received, dropped and energy consumption.
6. Results - Plot the graphs for packets sent, received, dropped and energy consumption for the two protocols.
7. Conclusion - Write summary of the report.
8. Reference style - Follow IEEE reference style
9. Appendix 1 - The tcl files for each routing protocol.
