Wireless Communications for SCADA Systems Utilizing Mobile Nodes

The Supervisory Control and Data Acquisition (SCADA) systems are collecting data from various sensors nodes deployed in remote locations and then transmitted to a central controller which then manages and controls this data. Wireless communications for SCADA is required to applications where wired communications to the remote site is too expensive or it is too time consuming to construct wired communications. Utilization of wired or line communications is becoming impractical as the scope is increasing widening. This paper discusses the role of wireless communications for SCADA systems.
