Project Description

Develop Simulation Model for IEEE 802.11g Wireless Network Standard.

Focussing on the Distributed Coordination Function (DCF)

Test the performance of DCF under different conditions.

Compare results against two other systems Bianchi's Analytic Model Andrew Symington's Test Network

Scalability

Modularity

Expected Impact

Bring about a third method to test performance of 802.11

Flexible and Scalable Solution Can use different workload models Can be extended to any number of network stations

Key Success Factors

Can simulate IEEE802.11g under different workload conditions.

Produce results that should be comparable to the two other methods of performance analysis.
