Speed improvement of centralized scheduling algorithm on IEEE 802.15.4e TSCH netwok using heuristic method

Two of the IoT challenges are many nodes that active simultaneously and limited link bandwidth. The challenges can be overcome by using a scheduling algorithm for channel allocation. A known centralized scheduling algorithms that mentioned in standard is Traffic Aware Scheduling Algorithm (TASA). TASA is a scheduling algorithm devoted to the IEEE 802.1.4e TSCH network. With reference to TASA, this research proposes a scheduling algorithm, named as IR-TASA, which can improve the performance of TASA in terms of speed to create time slot schedule for IEEE802.15.4e network. The results show that IRTASA increases the speed up to 5 times as compared to TASA, with a relatively equal duty cycle.
