Abstract(s)

Envisioned to deliver superior Quality of Service (QoS) by offering faster data rates and reduced latency in 6G communication scenarios, pioneering communication protocols like the IEEE 802.15.7 are poised to facilitate emerging application trends (e.g. metaverse). The IEEE 802.15.7 standard that supports visible light communication (VLC) provides determinism for time-critical reliable communication through its guaranteed time-slots mechanism of the contention-free period (CFP) while supporting non-time-critical communication through contention-access period (CAP). Nevertheless, the IEEE 802.15.7 MAC structure is fixed and statically defined at the beginning of the network creation. This rigid definition of the network can be detrimental when the traffic characteristics evolve dynamically, for example, due to environmental or user-driven workload conditions. To this purpose, this paper proposes a resource-aware dynamic architecture for IEEE 802.15.7 networks that efficiently adapts the superframe structure to traffic dynamics. Notably, this technique was shown to reduce the overall delay and throughput by up to 45% and 30%, respectively, when compared to the traditional IEEE 802.15.7 protocol performance under the same network conditions.
