摘要:Most of the tasks in wireless sensor networks (WSN) are requested to run in a real-time way. Neither EDF nor FIFO can ensure real-time scheduling in WSN. In this paper some characteristics and limitation of operating design in wireless sensor network are discussed. During this paper the researchers will discuss about message scheduling and scheduling strategy for sensor network O.S, for this reason the researchers analysed system architecture of TinyOS, FIFO scheduling TinyOS, task mechanism and event-driven mechanism. Main purpose of these articles is presenting a real-time scheduling strategy (RTS). RTS utilizes a pre-emptive way to ensure hard real-time scheduling. The experimental results prove that RTS has a good performance both in communication throughput and over-load
