No sooner have we accepted IoT than innovations
are transforming how this hyperconnected world will be implemented. Among the
emerging technologies is fog computing, which moves computing closer to the
end-user to decrease latency and bandwidth overload while improving access.
The fog network architecture taps client
and/or edge devices to handle much of the demands of IoT. As such, fog
computing peels away from central cloud storage, backbone networks, and network
gateways. It is inherently decentralised, distributing compute cycles wherever
they can increase efficiency, so less volume and more refined data is transmitted.
There are many benefits to fog computing in
the emerging IoT landscape. It can drive:
Reductions in data volumes sent to the
Network resource savings
Improved data access times
As with any technology, fogging has its
challenges as well:
Fog devices are new, and therearen’t many choices yet. Quality has
not caught up with the concept.
Any fog device exists on the LAN and must be
managed. A plethora of them can make for network administration headaches.
Security isn’t wholly buttoned up. Fog
computing is vulnerable to man-in-the-middle attacks and remote authentication
schemes, not to mention new physical security problems caused by its
At this point, the industry is sure about
IoT—it’s here and it’s expanding. Nonetheless, given the need to solve the data
volume transmission problem, the IoT future is definitely foggy.
