| Abstract | The widespread growth and popularity of the internet and wireless devices have placed greater demand on the need for wireless local area networks (WLANs) (Motchanov, 2010). WLANs are presently being used to enable many users share available network resources in a fast and convenient way (Obaidat et al., 2008). WLANs popularity began when the United States Federal Communications Commission (FCC) opened up the Industrial Scientific and Medical Band (ISM) to the public (Obaidat et al., 2008). Several companies developed wireless solutions during this period but these solutions did not interoperate among themselves. The IEEE802.11 WLAN working group addressed this issue by developing different IEEE802.11 WLAN standards which can be followed by different vendors. They defined the physical layer to specify multiple communication data rates to be selected for transmission depending on the quality of the current link (SNR observed) (Metreaud, 2006). The degree of performance enjoyed by WLAN users depend largely on the network design. Throughput is an important network parameters identified to be directly influenced by the SNR received by the end users (Metreaud, 2006). Throughput depends on the selected communication data rate which is also directly dependent on the SNR observed. This chapter presents a background study on 802.11 WLANs, their network performance metrics (throughput, SNR, Received Signal Strength Indication, etc.), interactions between TCP throughput, losses, link adaptation and SNR in WLANs. Cross layer modelling principles and research that models throughput based on SNR only are also presented. Throughput which is largely dependent on the observed SNR is identified in this chapter as a major metric for characterizing IEEE802.11 WLANs. |
