A Prototype Implementation of Wi-Fi Seamless Redundancy with Reactive Duplication Avoidance
Gianluca Cena, Stefano Scanzio, Adriano Valenzano · 2018
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.
