Remote Monitoring and Controlling of Gas Sensor Using VPN
Connection
Abstract
The use of sensors is witnessing a dramatic increase. They are applied in diverse fields
such as military, industrial, health, and smart homes. Monitoring these sensors could be made
remotely with the help of communication networks. In order to use the widely available
Internet for such applications the security issues become a big concern. Virtual Private
Networks (VPN) provide a security blanket to the use of the Internet for remote monitoring
and controlling. In this work a sensor network is practically implemented consisting of a WLAN
Sensor_Actuator side, a WLAN Coordinator host, and a remote host connected to the
coordinator through a VPN connection using Gbridge software. LabVIEW software is installed
on the Sensor_Actuator host and the Coordinator host as a graphic user interface environment
for monitoring the gas sensor reading and controlling an actuator. The measured round trip
time (RTT) between the Sensor_Actuator side and the Coordinator side is found to be less
than 15mS, while it was less than 300mS between the Coordinator side and the remote host.
