KF7031 Wireless Networks and Security Assignment - Northumbria University Newcastle, UK
Title: 802.11 WLAN data throughput and security overheads
The following Learning outcomes will be addressed in this assignment:
1 - Be able to describe, explain critically and analyse wireless data communication technology along with associated security issues.
2 - Be able to analyse and model wireless behaviour using appropriate mathematics.
3 - Critically analyse enterprise requirements for wireless systems.
4 - Critically analyse 802.11 protocol information.
5 - Make critical decisions about designing secure wireless networks.
Instructions on Assessment - Your work must be presented in the form of a short technical paper and be no longer than 7 sides plus a facing page that includes the abstract, but excluding the appendix and references. This should be printed on A4 paper and use a font size no smaller than 10. A mark penalty of -10%/additional page will be applied for submissions longer than required. For completeness you must include a detailed table of results within an appendix (not included in page count). You may if you wish include further additional material in an appendix but this will not contribute to the marks and you should not explicitly refer to any appendix to illustrate results etc. You could use an appendix to present a full derivation of formula.
Practical work (or Simulation) -
You need to perform a number of experiments to measure actual throughput rates for a system using physical experiments or a network simulator of your choice (OMNET++ or OPNET or any other suitable simulator). You are required to measure data throughput using an access point supporting the 802.11 mode (a, b or g) you chose to investigate. For practical experiments, throughput can be measured using JPERF and IPERF traffic generation software or the more sophisticated ZTI traffic generator. Wireless traffic (i.e. traffic through the air between the AP and WNIC) needs to be monitored using Omnipeek or AirPCap on a probe WNIC. For a simulation environments, select appropriate configurations and parameters to obtains the throughput results.
Throughput measurements should be taken for the maximum speed available for your chosen standard. You will need to analyse the data collected carefully and compare your observations with the theoretical predictions you have developed.
Additionally, you need to measure throughput with your chosen security mechanism implemented on the wireless link. You should end up with a set of results, one with security on and one with security off, so you can make clear comparisons of your observations.
Before carrying out any throughput measurements you should assess the channel busyness using a Channelizer Pro spectrum analyser. Chose the quietest channel available for your work. You need to comment in your results and discussion section the impact of interference and other Wi-Fi transmissions on the same channel.
