TSCH (Time Slotted Channel Hopping) networks are excellent candidates to support applications of industry 4.0 with latency, energy and reliability requirements. However, such applications have to face topology, traffic or even application changes. How can TSCH networks adapt to such changes? We propose a solution ranging from network construction to data gathering. We show how the schedule can adapt to changing topology, traffic and application conditions. We compute the theoretical bounds with regard to key performance indicators and compare them with the values obtained by NS3 simulation.
