LOST: Localized Blacklisting Aware Scheduling Algorithm for IEEE 802.15.4-TSCH Networks

Abstract : Industrial applications require more and more low-power operations, low-delay, deterministic communications as well as end-to-end reliability close to 100%. IEEE 802.15.4-TSCH (Time-Slotted Channel Hopping) relies on a channel hopping technique while scheduling properly the transmissions to provide a high end-to-end reliability. Because of external interference, some channels may perform very poorly locally, which impacts negatively the reliability for some radio links. We propose here the first distributed scheduling solution which reactively allocates the cells to each pair of nodes while also considering local blacklists. These local blacklists are constructed on a per-radio link basis to reflect the actual performance encountered locally. Our simulations highlight the relevance of our distributed blacklisting aware scheduling algorithm to improve both the reliability and the delay efficiency compared with DeTAS, a state of the art distributed solution.
