The paper presents the performance advantage of Wireless Token Ring Protocol (WTRP) versus IEEE 802.11 in DCF mode. WTRP is a medium access control (MAC) protocol and is designed to provide quality of service in WLANs. WTRP supports guaranteed QoS in terms of bounded latency and reserved bandwidth which are crucial constraints of the real time applications and unapplicable in a IEEE 802.11 network. WTRP is a distributed MAC protocol and partial connection is enough for full connectivity. The stations take turn to transmit and are forced to suspend the transmission after having the medium for a specified amount of time. WTRP is robust against wireless medium imperfections. The DCF mode of IEEE 802.11, also a distributed MAC protocol, is based on contention among stations and is not homogeneous due to the existence of hidden terminals and random behavior. Consequently, QoS is not provided.
