Overview: QoS provision in multi-hop IEEE 802.11 networks is very challenging due to the interference nature of wireless medium and the contention-based behavior among neighboring nodes. In such networks, one of the key questions for QoS support is: given a specific topology and traffic condition, how much bandwidth can be utilized along a path in the network without violating QoS demand of existing traffic? In this paper from IEEE, an analytical model for multi-hop IEEE 802.11 networks is derived to calculate the bandwidth that can be utilized along a path without violating QoS requirements of existing traffics.
