Bottleneck Analysis for Two-Hop IEEE 802.11e Ad Hoc Networks
Recently, a quality-of-service (QoS) extension of the IEEE 802.11 standard (known as IEEE 802.11e) for wireless LANs has been proposed. We present a versatile and accurate performance model to study how these new QoS enhancements can be used to improve the performance of wireless nodes competing for bandwidth in a multi-hop ad hoc network. The paper presents the QoS enhancements, and shows how they can be modeled using a simple, yet effective, parameterized quasi-birth-death model. The model is developed hierarchically, in that results at packet level (e.g., as developed by Bianchi and others) are used in our flow-level model, in which a single bottleneck station interacts with a time-varying number of traffic sources. Thus, we are able to study the impact of the QoS enhancements on the flow-level performance. This has not been done before. The results of our analyses are compared with extensive simulations (using Opnet), and show excellent agreement for throughput, mean number of acti...
