| 英文摘要: |
| Traditional probabilistic task scheduling algorithm in wireless networked control system suffered from low efficiency and long delay. To solve the spatial and temporal priority problems, a probabilistic model is constructed, and a high efficient task scheduling algorithm is developed. By analyzing the schedulability of a task list, the success rate of scheduling is improved. Simulation experiments show that the algorithm is feasible for real-time systems. Moreover, the optimized algorithm has much improvement on performance compared with the existing traditional algorithms. |
