In-Field Soil Property Monitoring using Hybrid Sensor Network

摘要: A hybrid soil sensor network (HSSN) for in-situ, real-time property monitoring was developed and deployed to an experimental field. The HSSN included a local wireless (LWSN), which formed by multiple nodes installed at selected locations in the field acquire readings from sensors transmit data wirelessly sink on edge of field; long-distance cellular communication (LCCN). were transmitted remote web server through General Packet Radio Service (GPRS) transfer service provided commercial provider. functioned as gateway received all nodes; repacked data, buffered according schedule, packets LCCN. implemented PC receive, store, process display real time data. Data based energy-aware self-organized routing algorithm. completed has been operation since it May 4th, 2009 performed satisfactorily.
