  In the last decades, technological developments in wireless communications
have been coupled with an increasing demand of mobile services. From real-time
applications with focus on entertainment (e.g., high quality video streaming,
virtual and augmented reality), to industrial automation and security scenarios
(e.g., video surveillance), the requirements are constantly pushing the limits
of communication hardware and software. Communications at millimeter wave
frequencies could provide very high throughput and low latency, thanks to the
large chunks of available bandwidth, but operating at such high frequencies
introduces new challenges in terms of channel reliability, which eventually
impact the overall end-to-end performance. In this paper, we introduce a proxy
that coordinates the physical and transport layers to seamlessly adapt to the
variable channel conditions and avoid performance degradation (i.e., latency
spikes or low throughput). We study the performance of the proposed solution
using a simulated IEEE 802.11ad-compliant network, with the integration of
input traces generated from measurements from real devices, and show that the
proposed proxy-based mechanism reduces the latency by up to 50% with respect to
TCP CUBIC on a 60 GHz link.
