Abstract

Most of energy control or Supervisory Control and Data Acquisition (SCADA) systems are very dependent on advanced technologies and on traditional security mechanisms for protecting the a system against anomalous events. Security mechanisms are not enough to be used in critical systems, since they can only detect anomalous events occurring at a certain moment in time. For this reason it becomes of paramount importance the usage of intelligent systems with capability for preventing anomalous situations and reacting against them on time. This type of systems are, for example, early warning systems (EWS). In this paper, we propose an EWS based on Wireless Sensor Networks (WSNs) (under the ISA100.11a standard) and reputation for controling network behavior. The WSN are organized into clusters where a cluster head (CH) is designated. This CH will contain a Reputation Manager Module. The usability of this approach is also analyzed considering a smart grid scenario.
