Study On Soil Water Wireless Sensor Network Based On GPS Technology

The study is based on urban greenfield grassland with GPS technology wirless sensor network face applicatied fundermental problems.Some key methods and techniques including the design of a wirless sensor network applied in urban greenfield grassland,the research of anchor,analysis of location and experiment,sensor nodes deployment method.Therefore,it is in order to provide better principle for application of WSN in grassland environmental monitoring.The main studies are as follow:1.Based on Zigbee protocol,the paper provided design method of wireless sensor network in urban greenfield lawn application,including routing algorithm,MAC protocol research.2.The design of positioning nodes is the basis of wireless sensor networks research.Through practical application of the demand,design corresponding hardware and software.3.Research on positioning problem.Through experiments summarized the relationship between RSSI and distance model,and applied to the corresponding distance-based positioning algorithm. Provide the knowledge base for the study of positioning in the future.4.Using regular mesh in the deployment of sensor nodes.Do the analysis of several regular meshs.
