The ability to access low-level IEEE 802.11 MAC primitives, and in particular to manage single transmission attempts in software at the user space level, is a prerequisite for many application scenarios based on Wi-Fi and characterized by tight timings constraints. Seamless redundancy, traffic scheduling, and TDMA techniques are just a few significant examples. In this paper, a novel software architecture...
Seamless redundancy is an effective way to increase communication quality over wireless channels, and provides a degree of reliability that meets the standards demanded by many distributed control applications in industrial plants. Unfortunately, wireless spectrum usage increases consequently, which is often unacceptable as this is a shared and limited resource. Wi-Red is a proposal that applies seamless...
