Resumo(s)
Although power-line communication (PLC) is not a
new technology, its use to support communication with
timing requirements is still the focus of ongoing
research. Recently, a new infrastructure was presented,
intended for communication using power lines from a
central location to geographically dispersed nodes
using inexpensive devices. This new infrastructure uses
a two-level hierarchical power-line system, together
with an IP-based network.
Within this infrastructure, in order to provide end-toend
communication through the two levels of the powerline
system, it is necessary to fully understand the
behaviour of the underlying network layers. The masterslave
behaviour of the PLC MAC, together with the
inherent dynamic topology of power-line networks are
important issues that must be fully characterised.
Therefore, in this paper we present a simulation model
which is being used to study and characterise the
behaviour of power-line communication.
