A Prototype Implementation of Wi-Fi Seamless Redundancy with Reactive Duplication Avoidance

Applying link-level seamless redundancy to Wi-Fi noticeably ameliorates communication quality, but also doubles
spectrum consumption. The adoption of mechanisms, operating at runtime, aimed at preventing the transmission on air of
inessential frame copies, permits to lower the generated traffic tangibly and also improves behavior further.
In this paper, a prototype setup is described, based on redundant Wi-Fi, which carries out reactive duplication avoidance
completely in software. This makes it mostly independent from wireless adapters hardware. An experimental evaluation
of its performance showed that, although implementation is preliminary, this solution is able to outperform plain seamless
redundancy.
