Abstract
RESEARCH QUESTION: How does network performance decrease as the number of nodes of network increases? 4 sub-questions: Which encryption protocol is the best one for multi-node wireless network environment? How the network throughput will be effect by increasing the number of wireless nodes in a large-scale wireless network? How the network delay will be effect by increasing the number of wireless nodes in a large-scale wireless network? How different is the data get from test bed implementation and simulation implementation? 802.11 WLAN becomes one of the most implementation of wireless network technology. However, the network performance is always a significant concern for users who is willing to migrant from wired to wireless network. Previously, a test-bed project has been conduct for 802.11n draft network performance against encryption protocols. This project is an extension of the previous experiment that increases the scale of the network by using simulations. The project tests network performance parameters such as throughput, delay, media access delay, and retransmission attempts against the change of number of APs and wireless nodes. Final result will be given based on the analyzed result data.
