Abstract

We propose the prioritized binary countdown (PBC) scheme for effective quality of service (QoS) supports in mobile ad hoc networks. We evaluate the performance of PBC, IEEE 802.11,802.11e, and two extensions to 802.11e in terms of their differentiation capability, throughput, delay, discarding ratio, blocking rate, and collision rate. Our simulation results show that PBC has considerably higher throughput and smaller delay, dropping ratios, blocking rates, and collision rates as compared to CSMA/CA of IEEE 802.11. We also show that PBC have considerably stronger differentiation capability than IEEE 802.11e and its extensions in multihop ad hoc networking environments
