The IEEE 802.15.4e amendment provides different modalities over which Wireless Sensor Networks (WSNs) can be deployed, even with strict requirements in terms of latency and determinism; still, there seems to be room for improvement. This paper proposes two enhancements for IEEE 802.15.4e LLDN mode: (1) allowing a reduced and more predictable configuration time and (2) focusing on the worst-case latency for high-priority traffic. A comparison with standard LLDN is then performed and evaluated, either through Monte Carlo simulations or analytically.

Abstract
The IEEE 802.15.4e amendment provides different modalities over which Wireless Sensor Networks (WSNs) can be deployed, even with strict requirements in terms of latency and determinism; still, there seems to be room for improvement. This paper proposes two enhancements for IEEE 802.15.4e LLDN mode: (1) allowing a reduced and more predictable configuration time and (2) focusing on the worst-case latency for high-priority traffic. A comparison with standard LLDN is then performed and evaluated, either through Monte Carlo simulations or analytically.File in questo prodotto:
