Dynamic Cell Scheduling Technique Based on Packet Queue Utilization in 6TiSCH Networks

The 6TiSCH network utilizes the IEEE 802.15.4 Time Slot Channel Hopping MAC protocol, with the Minimum Scheduling Function aiming for efficient traffic management and communication scheduling. Nonetheless, MSF's independence from packet queue utilization can lead to packet loss due to overflow from network traffic variations. This paper proposes dynamically adjusting cell addition and deletion cycles based on packet queue usage and network traffic insights to mitigate queue overflow and minimize idle listening. Evaluated through a 6TiSCH simulator, our approach demonstrated enhancements in packet transmission rates, throughput, latency, and traffic segment performance.
