Thorough Performance Evaluation & Analysis of the 6TiSCH Minimal Scheduling Function (MSF)

IEEE Std 802.15.4-2015 Time Slotted Channel Hopping (TSCH) is the de facto Medium Access Control (MAC) mechanism for industrial applications. It renders communications more resilient to interference by spreading them over time (time-slotted) and frequency (channel-hopping) domains. The 6TiSCH architecture bases itself on this new MAC layer enable high reliability communication in Wireless Sensor Networks (WSNs). In particular, it manages construction of a distributed schedule that continuously adapts changes network. paper, we first provide thorough description architecture, Operation Sublayer (6top), Minimal Scheduling Function (MSF). We then study its behavior reactivity from low traffic rates employing Python-based simulator. Our performance evaluation results demonstrate convergence pattern MSF root cause majority packet losses observed also show prone over-provisioning network resources, especially case varying load. propose mathematical model predict MSF. Finally investigate impact parameters scheduling function.
