Abstract
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.
