Abstract
The standardized Medium Access Control (MAC)
protocols for Power Line Communication (PLC) networks
(Homeplug and IEEE 1901) are based on the Distributed Coordination
Function (DCF) defined for IEEE 802.11. However,
the backoff procedure is modified with the goal of decreasing
the collision probability. In this work, the backoff procedure of
PLC MAC protocols is compared to DCF in different traffic
conditions and scenarios, including scenarios with all nodes in
coverage range as well as topologies with hidden and exposed
terminal problems. The goal is to demonstrate and quantify the
pros and cons of each approach in each particular case. Results
show that the modified backoff procedure of the Homeplug MAC
reduces the collision probability when there is high contention.
However, the performance is not always improved compared to
DCF. Moreover, when Homeplug provides better performance
than the vanilla DCF, we show that the DCF can be easily tuned
to achieve similar gains.
