As mobile computing becomes ubiquitous and airspace more congested, it is increasingly important to fairly distribute bandwidth between competing wireless devices in order to ensure predictable and satisfactory performance for end users. In prior work, we have proposed a cross-layer approach called Shaper [3, 4] that uses TCP and a central router rather(More)
It is well known that competition between 802.11 wireless flows can lead to severe unfairness problems. In this paper we show that certain flows can be denied from their fair share of network access for long periods of time due toinequitable channel conditions. We argue that this unfairness problem is likely to get worse as the use of wireless in terms of(More)
