The Application of Wireless Sensor Network and Middleware in the Internet of Things

摘要

Thanks to the sensors Wireless Sensor Networks (WSNs) nodes are provided with, and to their offer capabilities and ubiquity, these networks become extremely suitable for many applications that conventional wireless or cabled networks are unable to handle. One of these still underdeveloped applications is monitoring hydrologic stations. This is an especially interesting application regarding their water level or rainfall, for any detected hazardous parameter can be notified not only to the hydrologic station as a warning, but also to any third party that may be helpful under critical circumstances, such as related hydrologic stations or water conservancy department. We build and deploy a system to monitor the water level data from gauge stations in the Taihu Lake. Along with our middleware developed, sensors have been deployed by uses of several nodes conducting as the nodes of a WSN. The hydrologic data extracted from the environment, combined with the information get from the hydrologic station, will constitute the basis of the services that can be achieved.
