| Summary: | The loss of the integrity and/or availability of data
has the potential to diversely affect power utility core
operations. Supervisory Control and Data Acquisition
(SCADA) system is a computer system for collecting and
analyzing data in almost real-time fashion for monitoring
purposes. SCADA refers to the combination of telemetry and
data acquisition. Communication plays, thus, a core role in
SCADA systems. The use of wireless sensor network (WSN)
can, however, lead to a more flexible and powerful protection
scenarios than the current used wired sensor. Merit to
Zigbee/IEEE802.15.4 as one of the promising WSN standards
due to its low cost of deployment, low power, low data rate,
short range, simplicity and free licensed spectrum. While a
beacon-enabled mode is adopted for energy efficiency
operations with a multi-hop mesh network built up for large
coverage, IEEE802.15.4 standard does not provide any
mechanisms for a beacon-enabled mode in multi-hop mesh
networks. Hence, in order to provide a real-time data exchange
and thus, predict a real-time system control, a Novel
Zigbee/IEEE802.15.4 MAC Protocol for SCADA system is
modeled in this paper. The protocol performance is evaluated
using NS-2 Simulation and the preliminary results are
encouraging.
