In this paper, a hybrid spatial and temporal scheduling algorithm for wireless networked control system, which takes the distance between robot and task region as well as the deadline of a task into consideration is proposed. In our method, we quantify spatial and temporal factors 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.
Preemptions are necessary to obtain feasible schedule for real-time processing. A nonpreemptive scheduler can block higher priority transactions affecting schedulability of the system. This paper presents deferred pre...

Several task clustering heuristics are proposed for allocating tasks in heterogeneous systems to achieve a good response time in data intensive jobs. However, one of the challenging problems is the process in task scheduling after task allocation by task clustering. We propose a task scheduling method after task clustering, leveraging worst schedule length (WSL) as an upper bound of the schedule length. In our proposed method, a task in a WSL sequence is scheduled preferentially to make the WSL smaller. Experimental results by simulation show that the response time is improved in several task clustering heuristics. In particular, our proposed scheduling method with the task clustering outperforms conventional list-based task scheduling methods. Copyright 2016.
