| Summary: | The future of Smart Grid is based on grid-integrated
real-time communications between the grid elements of generation,
transmission, distribution and loads. Due to Zigbee/IEEE 802.15.4
standard’s features such as low cost, low power, low data rate, short
range, simplicity and free licensed spectrum which makes Zigbeebased
wireless sensor networks (WSNs) the wireless technology of
choice for smart grid applications. This paper focuses on the
electricity distribution layer, ranging from Advanced Metering
Infrastructure (AMI) gateways at the house-hold to the distribution
point where a multi-hop mesh network is built for large coverage
data exchanges. Although beacon-based mode of operation is
adopted in IEEE802.15.4 standard, it does not, however, specify
any mechanism to enable beacon mode in mesh networks.
Therefore, in this paper, the Zigbee/IEEE 802.15.4 MAC protocol
is modified to suit the beacon-based wireless sensor multi-hop mesh
networks application. Such network configuration is expected to
proliferate in is smart grid auto-metering scenarios. A simulation
model was built and validated using the network simulator (NS-2)
and the preliminary results showed considerable enhancements as
expected for the ZigBee/IEEE 802.15.4 MAC protocol. |
