Abstract

The advantages of 802.11 wireless networks have led to their widespread use which in turn has intensified the problem of interference, especially in dense urban settings. Such networks are close to one another but not centrally managed and do not share any high-speed wired backend. We present a system that leverages subcarrier selection, power allocation, nulling and multi-stream transmission but most importantly does so in a loosely cooperative manner between participating hosts, leading to considerable throughput improvements over the status-quo.
