Collision-aware design of rate adaptation for multi-rate 802.11 WLANs
One of the key challenges in designing a rate adaptation scheme for IEEE 802.11 wireless LANs (WLANs) is to differentiate bit errors from link-layer collisions. Many recent rate a...

Flow-level QoS for a dynamic load of rate adaptive sessions sharing a bottleneck link
We consider the flow-level quality of service (QoS) seen by a dynamic load of rate adaptive sessions sharing a bottleneck link based on fair share bandwidth allocation. This is o...
