Resumo
We carried out a study on throughput estimation based on analysis and modeling of
the medium access control in HomePlug 1.0 standard based PLC networks. The data
communication using electrical energy wires has advantages such as presenting
characteristics of ubiquity due to the existent infrastructure, but faces significant obstacles as
fading and noise. The main standard of this kind of home network is the HomePlug, which
defines a protocol based on the method of multiple access with collision avoidance
(CSMA/CA). The HomePlug adds to the CSMA/CA a technique called deferral counter (DC)
that adapts the contention of the nodes in accessing the medium according to network load.
The objective of this work is todo a comparative study of the throughput, which is the ratio of
the packet payload, i.e., the amount of data that is inserted into the body of the datagram, and
the frame transmission time. To this end, we evaluate what is the theoretical maximum
throughput of the PLC channel, we developed a simulator for the CSMA/CA and we propose
a simple probabilistic model to describe the throughput on the network PLC. Finally, we
make a comparison between the results obtained with the simulator and the probabilistic
model to those observed from a real PLC network, proving that the results of the theoretical
maximum throughput and the simulation results are close and that the probability model
becomes a tool for calculating throughput in PLC networks.
