- Admission Control and Service Differentiation Based QoS Provisioning for Mobile Ad Hoc Network
- Service differentiation is the key to today's Internet QoS. However the assumption of static network topology and stability of links make the direct application of DiffServ in mobile ad hoc networks unfeasible. This paper presents admission control and service differentiation mechanism that works only in network layer and does not...

- QoS Mechanisms for the MAC Protocol of 802.11 WLANs
- There are two essential ingredients in order for any telecommunications system to be able to provide Quality-of-Service QoS guarantees: Connection Admission Control CAC and service differentiation. In Wireless Local Area Networks WLANs, it is essential to carry out these functions at the MAC level. The IEEE 802.11e draft standard includes...

- An Analytic Study of Tuning Systems Parameters in IEEE 802.11e Enhanced Distributed Channel Access
- This paper derives, based on the analytical model developed by Cali et al., a multi-class model to study how to adaptively tune all the parameters in IEEE 802.11e EDCA and support service differentiation in WLANs. Through analytical modeling, it demonstrates that by assigning appropriate different transmission probabilities (or contention window...

- Competitive and Considerate Congestion Control for Bulk-Data Transfers
- The current Internet features traffic from diverse applications; ranging from delay-sensitive web browsing to delay-insensitive data file transfers. This motivates service differentiation, yet router-centric solutions. The current practice relies on a limited service differentiation at network edges. End-hosts often implement such emulators of low priority service to differentiate low and...

- Random-Access Scheduling With Service Differentiation in Wireless Networks
- Recent years have seen tremendous growth in the deployment of Wireless Local Area Networks WLANs. An important design issue in such networks is that of distributed scheduling. The lack of centralized control leads to multiple users competing for channel access. This leads to significant throughput degradation. This paper proposes a...

- Resolving 802.11 Performance Anomalies Through QoS Differentiation
- It was recently shown that 802.11b MAC has an "Anomaly" that the throughput of high bit-rate terminals in good channel condition is down-equalized to that of the lowest bit-rate peer in the network. This paper analytically proves that the phenomenon can be cleanly resolved through configuring the initial contention window...
