Sensor-based Architecture for Quality-of-Service Support in WLANs

As Wireless Local Area Networks garner increasing interest from network access providers and customers, the ability to offer Quality-of-Service guarantees to multimedia applications remains an unresolved challenge. Limited bandwidth capacities and increasing traffic volume exacerbated by the need to maintain service quality in the presence of user mobility, entails radical rethinking of WLANs design. In this paper, we present a sensor-based resource management framework for QoS provisioning in WLANs, while retaining backward compatibility with existing implementations. We validate the efficiency of our design through theoretical analysis and demonstrate the benefits of our approach by simulations.
