|Title:||RESERVATION POLLING: AN EFFICIENT .MULTI-ACCESS TECHNIQUE FOR IEEE 802:11 WLANs|
|Keywords:||ELECTRONICS AND COMPUTER ENGINEERING;RESERVATION POLLING;MULTI-ACCESS TECHNIQUE;WLANs|
|Abstract:||This thesis is concerned with IEEE 802.11 wireless LAN. Current multi access protocols of these WLANs, used in the MAC layer, are inadequate in addressing the combined concerns of wireless and multimedia communications, because channel characteristics and traffic load distributions change dynamically with time in these WLANs. But many new protocols are being developed and reported in the literature. In this thesis we discuss two multi-access protocols for the Medium Access Control (MAC) layer of 802.11 WLAN viz., Simple Polling which has some limitations and another more efficient protocol called Reservation Polling which can guarantee quality of service, message priorities and provide efficient access to both data and voice. These two protocols have been simulated and a performance comparison has been made between them with respect to the throughput and channel utilization of data as well as voice. It has been shown that reservation polling performs better than simple polling in low load conditions as well as in full load conditions. Further, a new proposal has been suggested to modify reservation polling to further improve its performance. The software is written in C++ and runs under LINUX environment.|
