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...
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...
This paper studies the performance of hybrid-ARQ (automatic repeat request) in Rayleigh blockfading channels. The long-term average transmitted rate is analyzed in a fast-fading s...
Abstract--Vehicular WiFi access is distinct in two respects, (i) continuous mobility of clients and (ii) possibility of predictable link quality. As part of this study, we aim to c...
Dense, unmanaged 802.11 deployments tempt saboteurs into launching jamming attacks by injecting malicious interference. Nowadays, jammers can be portable devices that transmit int...

While many existing rate adaptation schemes in IEEE 802.11 Wireless LANs result in severe throughput degradation since they do not consider the collision effect when selecting the...

—This paper presents a capacity analysis of a decode-and-forward (DF) cooperative network with adaptive source transmission. Three different adaptive techniques are considered: (...
There are various techniques for adapting the transmission rate of an application while maintaining the perceived quality at the receiver at acceptable levels. Shared channel syst...
— We consider the design of optimal strategies for joint power adaptation, rate adaptation and scheduling in a multi-hop wireless network. Most existing strategies control either...
Streaming high quality audio/video (AV) from home media sources to TV sets over a wireless local area network (WLAN) is a challenging problem because of the fluctuating bandwidth...
