Abstract
Millimeter wave (mmwave) communications will likely be
an enabler for 5G due to its multi-gigabit per second throughput
capabilities. Furthermore,mmWave communications will
have to be integrated in a new redesigned network required
by 5G to fulfill its ambitious targets. In this paper, we present
the design and implementation of a management agent for
wireless devices deployed in a heterogeneous SDN wireless
multi-hop research platform featuring mmwave communications
for crosshauling (backhaul and fronthaul) purposes.
The performance of the deployed mmwave network, based
on the IEEE 802.11ad standard, is measured employing this
agent. We measure the downtime in the presence of link
up/down events, with obtained response times in the order
of 10s-to-100s of milliseconds depending on the case. Furthermore,
the TCP performance over the multi-hop 802.11ad
mmwave network is also experimentally evaluated. In fact,
TCP throughput up to around 800Mbps are obtained for single
and multi-hop scenarios despite neighboring links using
the same channel. Finally, one can also observe the impact
of MTU size on TCP throughput, which may hinder the full
exploitation of the mmWave link capacity when combined
with other transport technologies, since the advantages of
big MTUs (much bigger than the typical 1500 bytes) offered
by mmwave devices may not be reaped.
