Competition: Adaptive Time-Slotted Channel Hopping
Résumé
Time-Slotted Channel Hopping (TSCH) from the IEEE 802.15.4-2015 standard uses channel hopping to combat interference and frequency-selective fading. It has attracted large attention from the research community due to its properties: high reliability in terms of packet delivery rates, and increased predictability in terms of energy consumption and latency, as compared to commonly used low-power CSMA MAC protocols. This work makes use of the Contiki OS implementation of the TSCH protocol. We extend the standardized TSCH protocol with adaptive channel selection, adaptive time synchronization , and adaptive guard time selection to improve its energy efficiency and reliability properties.
