Traffic Aware Multiple Slotframes scheduling algorithm in industrial IoT applications using IEEE802.15.4e TSCH

In order to solve the problem of scheduling delay-constrain heterogeneous data traffic in wireless industrial network, we propose the Traffic Aware Multiple Slotframes scheduling algorithm. It includes two main procedures: Compute available slot set and Allocate communication resources according to the requirement of data traffic. And then we give the detail description of the algorithm used in star topology and tree topology. We adopt the theoretically well-established graph theory methods of matching and coloring to solve the problem of communication resources allocation in tree topology. The experimental results show that the proposed method can achieve highly reliability and energy efficiency over other strategies that follows the new trend of developing green networking and support the emerging IoT application.
