Task urgency-based resource allocation algorithm in industrial Internet of things
the generation of tasks is observed to exhibit both continuity and periodicity
along with stringent latency requirements. These characteristics posed challenges to system's cost-efficiency. To address these challenges
a cost minimization resource allocation algorithm based on the urgency of tasks was proposed. By employing a genetic algorithm
the task offloading strategy and the system's resource allocation strategy were optimized. For offloaded tasks
they were scheduled according to their level of urgency. Additionally
the optimal transmission power for each task was calculated to meet latency constraints. Simulation results indicate that the proposed algorithm effectively reduces the overall energy cost of the system.
