Abstract: In this paper,a hybrid spatial and temporal scheduling algorithm for wireless networked control system,which takes the distance between robots and task region as well as the deadline of a tasks into consideration,was proposed.In our method,patial and temporal factors are quantified for eventually getting the priority queue.Based on the priority queue,the robot is able to execute the tasks sequentially.At last,extensive simulations are conducted to show the advantages of our spatial and temporal scheduling algorithm.Simulation results show that,on the premise of ensuring high successful scheduling rate,compared with previous method,our scheme show merits in terms of task requesting throughput,successful task solving ratio,average responding delay.
