Abstract : |
IEEE 802.11 is a Media Access Control (MAC) protocol which has been standardized by IEEE for Wireless Local Area Networks (WLAN). The IEEE 802.11 MAC protocol offers two types of services to its users: synchronous and asynchronous. This paper thoroughly analyzes, by simulation, the asynchronous part alone, when each station feeds the MAC protocol with data traffic patterns (in the following referred to as advanced data traffic) that are very close in shape to those generated by a terminal accessing, for example, the WWW service. Although the analysis shows that the performance of the IEEE 802.11 with advanced traffic is considerably worse than with Poissonian traffic, we can conclude that IEEE 802.11 still performs satisfactorily. Furthermore, our analysis is broadened to include higher medium capacities up to 10 Mbit/sec. This part of the analysis shows that the IEEE 802.11 MAC protocol is not adequate to work at speeds planned for the upcoming ATM Wireless LAN. The IEEE 802.11 is a standard for a WLAN covering both Physical and MAC layers, |
