Field Monitoring Using Sensor-Nodes with a Web Server

Abstract

In order to realize field and environment monitoring over long periods, we propose remote monitoring that responds flexibly and dynamically to change. Field Servers are one of the small monitoring sensor-nodes having a Web server accessed via the Internet and using a wireless LAN to provide a high-speed transmission network differing from traditional sensor-nodes. Monitoring with Field Servers enables easy installation, monitoring field information, and remote operation in any field. By providing a Web server for all modules, we can treat them collectively via the Internet. To evaluate this monitoring, we managed numerous Field Servers in different countries using an agent program. Field experiments show the system is safe and effective for remote monitoring applications.
