IEEE 802.11 Wireless LANs

Paper Summary:

This paper analyzes the efficiency of the access algorithms in IEEE 802.11 infrastructure wireless LANs. The first part of the paper provides an overview of the access algorithms that are in used in IEEE 802.11 implementations. A mathematical model of the carrier sense protocols is introduced and analyzed through the second part. The main part of the paper is devoted to simulation of IEEE 802.11 infrastructure networks. For this purpose a discrete event simulator has been designed and implemented. Finally the results are presented and discussed.

From the Paper:

"Nowadays, wireless LANs, also known as WLANs, are used widely as an alternative for the wired LANs. In Comparison with the traditional wired LANs, WLANs provide more flexibility and higher ROI (Return On Investment) for both providers and customers. Also in some cases (such as disaster discovery), it is impossible to set up a wired LAN. Since setting up a WLAN does not need a great starting investment (especially in the case of ad hoc operation), it is considered to be an ideal choice for any temporary network connectivity requirement in local scales. For these reasons, the WLAN's productivity has increased rapidly during recent years."
