Robust QoS Scheduling using alternate path for recovery from link failures in IEEE 802.15.4e

In this study, a robust QoS Scheduling scheme using alternate paths for recovery from link failures is proposed in the IEEE 802.15.4e with tree-based network structure. In the proposed scheme, margin slots used for alternate paths are included in the scheduling. Simulation results show that the margin slots of the proposed scheme results in higher throughput and a longer end-to-end delay performance.
