Project Description:

The proposed project involves implementing a multi-user, wireless Ethernet (IEEE 802.11b) network and simulating the network performance when voice, data, and video traffic are simultaneously transmitted across the network. The goal of the project is to learn about the relatively new and popular short-range wireless networking technology, and what the practical applications are for its bandwidth and range limitation. Once the system has been implemented attempts will be made to tweak the performance and determine factors that affect QoS.

OPNET is the current simulation tool of choice. There is an existing Wireless Ethernet implementation in OPNET. Our task includes determining what is already implemented and what additional features can be added.
