What is Device-to-Device (D2D) Communication?
Efficient communications is key to many distributed systems today. Device-to-Device (D2D) communications maintain
fast data flow and reduce data congestion by cutting out the need for a router or centralized network, instead
allowing devices to talk to each other directly.
At the core of D2D operation is the ability of devices to have a direct conversation between them, and only them,
with no central hub, routing or translation required. It has potential in multiple industries, but especially in the
field of telematics . These devices, when placed in each
of a fleet of vehicles , provide real-time data of
vehicle performance , location and more.
Using D2D, these systems could talk directly instead of going through a central hub.
Why Does D2D Matter?
There is a significant advantage in the device-to-device scenario, and if we look at our fleet management scenario
more closely, we can see why. If a vehicle has a mechanical failure, or its location suggests it has been stolen for
instance, a centralized system requires this information to be sent there, and then acted upon.
But with D2D, the telematics could talk directly to another telematics device in a nearby vehicle, allowing a faster
response to the issue.
But D2D brings other benefits too, connected systems
are a part of life today, with something as common as your home heating often using IoT devices to monitor temperature in rooms.
But what if each thermostat could talk directly to the heater, and adjust output itself, without needing to use a
central system controller? Cheaper, faster and more efficient, and not reliant on your home wi-fi either.
Its not perfect — Yet
While there are clear benefits in terms of speed of response to issues and so on, there are challenges with a D2D
system. The first is getting various devices speaking to each other at all, especially in some areas such as
automotive when components are sourced from so many different manufacturers. But that is not all, security is a
concern with systems like this, as there is no oversight to monitor malicious intrusions.
So, while the idea of D2D is a good one, and it has the potential to change how we design systems in the future, the
technology still needs development and refinement.
