Abstract

This paper evaluates and compares MAC (medium access control) performance of ETSI HiperLAN/2 (H/2), IEEE 802.11 and W-CHAMB using stochastic computer simulations. H/2 adopts a fully centralized scheduler-oriented MAC approach that has best traffic performance in fully connected small networks. IEEE 802.11 uses a packet-oriented CSMA/CA MAC solution that is inefficient for short to medium packets, and cannot guarantee QoS in a multihop networking environment. COMNETS W-CHAMB supports high performance real time traffic services in multihop networks and achieves a high efficiency for short PDU trains
