Researt And Implementation Of Adaptive Positioning Method Based On Wireless Sensor Networks

Wireless sensor network as the core technology of the Internet age, the rapidinformation acquisition and processing technology with low cost, flexibility, lowpower consumption and stability characteristics make it emerge in many networkcommunication technology, and as a key to promote the development of the Internetof things. Wireless sensor network node location as a unique identifier, theeffectiveness of the network data in the sensor node positioning technology make itbecome one of the key technologies to promote the development of wireless sensornetwork. However, as a new field of technology, positioning of the node required lowpenetration technology, software and hardware combined with wide, higher demandof communication technology, a large number of data. Therefore, the demand oftechnical personnel in the practical application also higher, the system developmentcycle is long, the development efficiency cannot meet the needs of the currentsoftware development.The project studies a kind of quick and efficient method of sensor nodelocalization. Based on the research of traditional wireless sensor network localizationmethod and general positioning model, based on the location information of nodesembedded system and PC positioning information gathering process two aspects hascarried on the theory of abstract, coupled with positioning information transmissionmechanism and the calculation process, in the process of exploring the generaltransmission model of the embedded positioning system and PC data storagecalculation model. On this basis, the design and implementation is suitable for generalwireless sensor network node localization orientation of TinyOS intermediatecomponent and application service module, in the form of middleware to provideusers with quick orientation of embedded system and PC application configurationcall interface, simplifies the positioning information collection, transmission,calculation, storage process, in order to improve the efficiency of wireless sensornetwork positioning related applications development, reduce the workload andrelated technical requirements.The innovation of the subject is implementation of intermediate component andservice module, and proposed positioning middleware should reach the adaptive feature, including support for cross-platform system adaptability, more applicationoriented application adaptability, adapt to the complex environment of environmentadaptability three characteristics. This topic has been combined with the actual project,complete the rapid development of the project, such as simplified the developmentprocess and development personnel structure, the current part of the project hasapplied for national invention patent, reflects the strong application value.
