Abstract
Most of the tasks in wireless sensor networks (WSN) are requested to run in a real-timeway. Neither EDF nor FIFO can ensure real-time scheduling in WSN. A real-time scheduling strategy(RTS) is proposed in this paper. All tasks are divided into two layers and endued diverse priorities.RTS utilizes a preemptive way to ensure hard real-time scheduling. The experimental results indicatethat RTS has a good performance both in communication throughput and over-load.
