Wireless technologies and applications received great attentionin recent years. The medium access control (MAC)protocol is the main element that determines the efficiencyin sharing the limited communication bandwidth of thewireless channel in wireless local area networks (WLANs).The request-to-send/clear-to-send (RTS/CTS) mechanismis an optional handshaking procedure used by the IEEE802.11 wireless network to reduce the possibility of collision.The RTS Threshold (RT) value which determineswhen the RTS/CTS handshaking mechanism should be usedis an important parameter to investigate; since different RTvalues will produce different performance characteristics indata transmission. This paper presents an analysis of theinfluence of the RT parameter on the IEEE 802.11 wirelessnetwork, and gives a guideline to dynamically adjust theRT value. Simulation results of this paper show that theRTS/CTS mechanism should be always turned on (RT = 0)to achieve an excellent performance while saving complexwork designing a dynamic RT mechanism which will nothave notable effect.
