Performance Evaluation of Wlan by Varying Pcf, Dcf and Enhanced Dcf Slots To Improve Quality of Service
. Researchers have proposed a number of co-ordination functions in literature for improving quality of service. Each one is based on different characteristics and properties. In this paper, we evaluate the performance of wireless network using PCF, DCF & EDCF. We perform simulations using OPNET IT GURU Academic Edition simulator. In the performance evaluation of the co-ordination function, the ...
متن کاملPerformance Evaluation of WLAN Internet Sharing Using DCF & PCF Modes
Recently, Wireless Local Area Networks (WLANS) has become one of the most popular standards for wireless Internet access technology. IEEE 802.11 WLAN standard supports two kinds of access methods: DCF (Distributed Coordination Function) and PCF (Point Coordination Function).In this paper, DCF & PCF modes were used to manage internet sharing tasks. The characteristics obtained from bandwidth-del...
