A Survey On WSN OS Using Real-Time Scheduling Strategy

[Full Text]






Keywords: Wireless sensor networks, Real-Time Scheduling Strategy, TinyOS.



ABSTRACT: The Real time scheduling is Defined as a Systems whose correctness depends on their temporal aspects as well as their functional aspects. In this paper some characteristics and limitation of operating design in wireless sensor network are discussed. The TinyOS has been designed to run on a generalized architecture where a single CPU is shared between application and protocol processing. TinyOS is a component based operating system designed to run in resource constrained wireless devices. It provides highly efficient communication primitives and fine-grained concurrency mechanisms to application and protocol developers. A key concept in TinyOS is the use of event based programming in conjunction with a highly efficient component model. in this paper we mainly discussced about message scheduling and scheduling strategy for sensor network O.S &we analyzed the system architecture of TinyOS, FIFO scheduling TinyOS, task mechanism and event-driven mechanism.The Key characteristics for a real-time system are reliability (stability),predictability(it must be deterministic),performance (the faster the better),compactness to code size (space is money) and scalability.
